Your First 100 Days After Buying a Business: A Data-Backed Transition Guide

You’ve signed the contracts, settled the purchase, and the keys are in your hand. Now what?

The first 100 days of business ownership are widely regarded as the most critical period in any acquisition. Nearly 90% of private equity firms formulate a structured 100-day plan when acquiring a business — and for good reason (Grant Thornton & PitchBook). Research by PwC shows that companies with a robust pre-acquisition integration plan are 50% more likely to achieve their anticipated value from the deal (PwC).

Yet many first-time buyers step into ownership without a plan — and the numbers reflect it. A landmark study of 40,000 acquisitions found that 70–75% fail to deliver their intended value (Fortune, 2024). Much of that failure happens not at the deal table, but in the critical weeks and months that follow.

This guide gives you a structured, evidence-based plan for your first 100 days — tailored to the Australian regulatory environment and grounded in data on what actually works.

Before Day 1: Preparing for Settlement

Your 100-day plan should begin before you take ownership. Use the period between signing and settlement to:

  • Apply for your own ABN: The seller’s ABN cannot be transferred — you must apply for a new one through the Australian Business Register
  • Register for GST if turnover is or will be $75,000+ (you have 21 days from reaching the threshold, but register early to avoid delays)
  • Set up business banking and payroll systems so they’re ready from day one
  • Begin licence transfer applications: In Australia, business licence transfers can take up to 12 months (business.gov.au). Use the Australian Business Licence and Information Service (ABLIS) to identify every licence you need across federal, state, and local government
  • Negotiate the handover period: 75% of buyers want the former owner to stay on at least one day per week for six months post-sale — but only 56% of sellers are willing to do so (BizBuySell). Agree on this before settlement, not after

Days 1–30: Stabilise and Listen

The single most important rule for your first month: do not make major changes. Observe, learn, and build trust. The research is clear on what happens when you don’t.

Talk to Your Employees First

Employee retention is your most pressing challenge. The data is stark:

  • 33% of acquired workers leave within the first year — nearly three times the 12% departure rate for regular new hires (MIT Sloan)
  • An EY study found employee turnover after a merger averaging 47% in the first year and 75% within three years (SparkBay)
  • 90% of employees decide whether to stay or leave within the first six months of an acquisition (M&A Community)
  • Replacing a departing employee costs 50–200% of their annual salary when you factor in recruitment, training, and lost productivity

On day one, hold an all-employee meeting — ideally with the previous owner present. Communicate three things clearly:

  1. Their jobs are secure and you value them
  2. You’re here to learn from them, not to overhaul everything
  3. You have an open-door policy and welcome their questions

Understand Your Fair Work Obligations

If the acquisition qualifies as a transfer of business under the Fair Work Act 2009 (Part 2-8), specific obligations apply automatically. A transfer of business occurs when employees start with you within three months of leaving the seller, performing substantially the same work. In this case:

  • You must recognise prior service for parental leave, flexible working requests, and personal/carer’s leave — this is non-negotiable
  • If you are not an associated entity of the seller, you may choose not to recognise accrued annual leave and redundancy entitlements — but the old employer must then pay those out
  • Long service leave always transfers — the seller cannot pay it out and “reset the clock”
  • Any applicable enterprise agreements or modern awards may transfer with the employees

Contact Key Customers Personally

Customer retention is your second critical priority. Research shows that customers are up to three times more likely to switch after an ownership change (FI Works), and post-acquisition attrition rates of 20–30% or more are common.

A telling finding: customers who learn about an ownership change from external sources are twice as likely to leave compared to those who are informed directly (Escalent). They need to hear it from you first.

In your first week, personally contact the business’s top 10–20 customers. Introduce yourself, assure them of continuity, and ask what they value most about the business. This is both a retention strategy and a valuable source of intelligence.

Bain & Company documented how Westpac, upon acquiring St. George Bank, set a goal of losing zero customers — and achieved it. St. George’s churn rate actually dropped following the acquisition. The key was deliberate, proactive customer communication and maintaining the St. George brand identity. In contrast, First Union lost 20% of its customer base in the first year after acquiring CoreStates Financial, demonstrating the cost of getting this wrong (Bain & Company).

Your Day 1–30 Checklist

  • Hold an all-employee meeting with the previous owner present
  • Begin structured handover and training with the seller
  • Personally contact top 10–20 customers
  • Meet key suppliers and confirm terms
  • Confirm all ABN, GST, PAYG, and superannuation registrations are active
  • Notify the ATO of any updated ABN details within 28 days
  • Set up your own accounting, payroll, and banking systems
  • Obtain access to all business systems, passwords, and accounts
  • Review all current contracts — employment, supplier, lease, customer
  • Do not make staffing changes, process overhauls, or strategic pivots yet

Days 31–60: Analyse and Understand

With a month of observation under your belt, you now have the context to start analysing what’s working and what isn’t — without the risk of acting on assumptions.

Conduct an Operational Audit

  • Map every process: Document how work actually gets done (not how the manual says it should). Identify bottlenecks, redundancies, and inefficiencies
  • Review all subscriptions and services: New business buyers spend an average of $7,610 on accounting and HR services alone in the first year (BizBuySell). Audit existing subscriptions, software licences, and vendor contracts for waste
  • Assess technology: Are the current systems fit for purpose? Are licences transferable? What immediate upgrades are needed?

Deep-Dive into the Finances

  • Cash flow forecasting: Build monthly cash flow projections for the next 12 months. You should have 3–6 months of operating expenses in reserve (Biz2Credit)
  • Reconcile working capital: If your purchase agreement includes a working capital adjustment mechanism, now is the time to reconcile actual figures against the peg
  • Track every dollar: In aggregate, business buyers spend more than $26 billion (USD) on supplier services and products during their first year of ownership. Small expenses add up fast
  • Separate personal and business finances: If you haven’t already, ensure complete separation — this matters for tax, liability, and loan covenant compliance

Assess Your Team

By now you should have a clear picture of each employee’s strengths, role, and importance to the business. Research shows that employee problems are responsible for one-third to one-half of all merger failures (IMAA).

  • Identify your key people — who are the employees the business truly cannot function without?
  • Consider retention incentives for critical staff (bonuses, development opportunities, clearer career paths)
  • Note any skills gaps or training needs, but hold off on hiring unless absolutely necessary
  • Check that all employment contracts, modern award classifications, and superannuation payments are compliant — the Fair Work Ombudsman has been increasingly active in enforcement

Your Day 31–60 Checklist

  • Complete an operational process audit
  • Audit all subscriptions, contracts, and recurring expenses
  • Build 12-month cash flow projections
  • Reconcile working capital against the purchase agreement
  • Assess team capabilities and identify retention risks
  • Review supplier contracts and renegotiate where appropriate
  • Check licence transfer progress (follow up on applications lodged before settlement)
  • Begin building your own relationships with customers (beyond the initial introductions)
  • Start forming a picture of quick wins and longer-term improvement opportunities

Days 61–100: Implement and Grow

With two months of observation, analysis, and relationship-building, you’re now in a position to start making considered changes.

Implement Quick Wins

Start with changes that are low-risk, high-impact, and visible. These build confidence — both yours and your team’s. Examples might include:

  • Fixing a process that everyone complains about
  • Cutting a significant unnecessary expense
  • Improving a customer-facing touchpoint
  • Upgrading outdated equipment or software

Develop Your Growth Strategy

Now is the time to develop a 12-month strategic plan, working backwards to identify what needs to happen in the next quarter. Consider:

  • Revenue diversification: If you identified customer concentration risk during due diligence, begin building a broader customer base
  • Marketing: Develop or refresh the marketing plan. First-year marketing and advertising is consistently one of the top spending categories for new business owners
  • Operational improvements: Implement the efficiency gains you identified during your audit
  • People development: Invest in training — research shows effective training programs can enhance employee performance by up to 23% and smooth the ownership transition (IMAA via C-Suite Strategy)

Plan the Seller’s Exit

If the previous owner has been assisting during the transition, this is typically when their involvement starts winding down. The most common formal training period is 1–3 months, though some sellers continue in a consulting capacity for longer (Morgan & Westfield).

Before they leave, ensure you have:

  • All undocumented knowledge captured in writing
  • Personal introductions to every important relationship
  • A clear understanding of seasonal patterns and potential pitfalls
  • Access to all systems, accounts, and records
  • Their contact details for future questions (ideally included in the sale agreement)

Your Day 61–100 Checklist

  • Implement 2–3 quick wins identified during your analysis phase
  • Develop a 12-month strategic plan with clear milestones
  • Launch or refresh marketing initiatives
  • Address any compliance issues identified during your audit
  • Plan the previous owner’s transition out of the business
  • Ensure all licence transfers are complete or progressing
  • Conduct a financial health check — are actuals tracking to your projections?
  • Begin developing your own leadership rhythm (team meetings, reporting cadence, review cycles)

The Opportunity Ahead: Australia’s Succession Wave

If you’ve recently bought a business — or are considering it — you’re part of a historic shift. Baby boomers own approximately 80% of Australian SMEs, valued at roughly $3.5 trillion (Dynamic Business). Of those owners, 48% plan to exit within the next 1–5 years, yet only 24% have a succession plan in place.

Close to 4 million retiring baby boomers will exit the Australian workforce over the coming decade (ScotPac). For prepared buyers, this represents an unprecedented wave of opportunity — but only if you can manage the transition successfully.

Key Principles for a Successful Transition

Drawing from the research, several clear principles emerge:

  1. Patience pays: Resist the urge to “make your mark” immediately. The first month is for listening and learning
  2. People first: Employee and customer retention is more important than process optimisation in the early days. A 5% improvement in customer retention produces more than a 25% increase in profit (Bain & Company)
  3. Communicate proactively: Bad news travels fast; good communication travels faster. Tell your employees, customers, and suppliers about the change before they hear it from someone else
  4. Plan the handover: The seller’s knowledge is irreplaceable. Maximise the overlap period and document everything
  5. Watch the cash: More businesses fail from cash flow problems than from lack of profit. Monitor cash weekly, not monthly
  6. Get the compliance right: Australia’s regulatory environment — from Fair Work to the ATO to state-based licensing — has real consequences for non-compliance. Don’t defer these obligations

The first 100 days set the trajectory for everything that follows. Invest the time, follow the data, and build on what’s already working. If you’re looking for your next business opportunity, explore our current listings or get in touch with our team.

How to Finance Buying a Business in Australia: Every Option Explained

Financing is often the biggest hurdle standing between you and business ownership. According to the Reserve Bank of Australia, one in five Australian SMEs experienced difficulties obtaining finance in 2025 — and major banks reject 65–75% of business loan applications under $1 million (ScaleSuite).

But rejection from a Big Four bank doesn’t mean your acquisition dreams are over. The Australian business lending landscape has transformed dramatically in recent years, with non-bank lenders now preferred by 31% of SMEs — overtaking banks at 28% for the first time (ScaleSuite). A decade ago, fewer than 10% of borrowers planned to use non-bank lenders.

This guide walks you through every financing option available to Australian business buyers, with current rates, real approval data, and practical guidance on which option suits your situation.

How Much Will You Need?

Before exploring financing options, you need to understand the full cost of a business acquisition — which goes well beyond the purchase price.

The True Cost of Buying a Business

  • Purchase price: The agreed value of the business (typically 1–5x annual profits for small businesses)
  • Legal fees: $5,000–$20,000+ for solicitor review of contracts, due diligence, and settlement
  • Accounting fees: $3,000–$15,000 for financial due diligence and tax structuring
  • Stamp duty: Varies by state (see state comparison below)
  • Working capital: Typically 3–6 months of operating expenses to keep the business running while you transition
  • Loan establishment fees: 0.5–2% of the loan amount
  • Refurbishment or upgrades: Equipment, fit-out, or technology improvements

A common mistake is budgeting only for the purchase price and scrambling for working capital after settlement. As a rule of thumb, budget 15–25% above the purchase price for associated costs and operating reserves.

The Deposit Question: How Much Do You Need Upfront?

This is one of the most frequently asked questions — and the answer depends heavily on your lender and the security you can offer:

  • Traditional banks: 20–30% of the loan amount as deposit or equivalent equity
  • Alternative and private lenders: 10–15% deposit
  • General industry range: 20–35% of the total purchase price

Most lenders will finance 50–70% of the purchase price, expecting you to contribute the remainder through savings, home equity, or vendor finance (Small Business Loans Australia).

If you’re using home equity, a practical rule of thumb: your usable equity multiplied by four gives you an approximate maximum loan amount (based on an 80% loan-to-value ratio).

Option 1: Secured Bank Loans

The traditional route — and still the cheapest in terms of interest rates, if you can get approved.

What to Expect

  • Interest rates: 6.8–8.2% p.a. (variable, as at early 2026)
  • Loan amounts: Up to $10 million+
  • Approval timeline: 21–35 days for major banks
  • Security required: Typically residential or commercial property

The Big Four Banks

CBA, NAB, Westpac, and ANZ hold approximately 58% of the SME lending market. They offer the lowest rates but have the strictest criteria. Their approval rate for loans under $1 million sits at just 25–35% — meaning roughly two out of three applications are rejected (ScaleSuite).

Frustratingly, 61% of SMEs have abandoned bank loan applications due to excessive documentation requirements before even reaching a decision. If you’re going the bank route, be prepared to provide:

  • Business plan with financial projections
  • 2–3 years of financial statements (P&L, balance sheet)
  • Latest business and personal tax returns
  • Business Activity Statements (BAS) — must be up to date
  • 6–12 months of bank statements
  • The purchase agreement or contract of sale
  • An independent business valuation
  • Personal identification and asset/liability statements
  • Details of security/collateral

Sources: NAB, CommBank

Option 2: Non-Bank and Fintech Lenders

The fastest-growing segment of the lending market — and increasingly the first choice for business buyers.

Non-Bank ADIs

  • Market share: ~24% of SME lending
  • Interest rates: 7.5–9.5% p.a.
  • Approval timeline: 10–18 days
  • More flexible documentation requirements than major banks

Fintech Lenders

Lenders like Moula, OnDeck, Prospa, and Bizcap have captured roughly 18% of SME market share and are growing rapidly. OnDeck Australia reported a 42% year-on-year rise in loan applications in Q4 2025, with 34% of applicants seeking expansion or acquisition funds (ScaleSuite).

  • Interest rates: 9.5–18% p.a.
  • Approval timeline: 24–72 hours (80% funded within one week)
  • Approval rate: ~90% for businesses trading 3+ years
  • Loan amounts: Typically up to $250,000 unsecured (Moula offers up to $500,000)
  • No property security required for most products

The trade-off is clear: faster approval and fewer hoops to jump through, but significantly higher interest rates. For smaller acquisitions where speed matters, fintech can be the right choice.

Option 3: Vendor Finance (Seller Financing)

Vendor finance is when the seller agrees to finance part of the purchase price, with the buyer making payments over an agreed period after settlement. In the United States, approximately 70% of privately owned SME sales include some form of vendor financing (LINK Business). While precise Australian data isn’t available, usage is growing as buyers seek alternatives to traditional bank finance.

How It Works

  • The seller accepts a portion of the purchase price as deferred payments (typically 20–50% of the total)
  • Interest rates: 13–17% p.a. is typical for business sales (SprintLaw)
  • Term: Usually 1–5 years
  • Security: The seller typically holds a General Security Agreement (GSA) over the business assets

Why It Benefits Both Parties

For the buyer: Lower upfront capital needed, no bank approval required for the vendor-financed portion, and the seller has “skin in the game” — they’re invested in the business’s success after the sale.

For the seller: Broadens the pool of potential buyers, may achieve a higher sale price, and can spread capital gains tax liability across multiple financial years.

Key Considerations

  • Always have a solicitor draft a formal vendor finance agreement
  • Clearly define what happens in default — can the seller reclaim the business?
  • Agree on reporting obligations — the seller may want access to financial statements during the payment period
  • Consider combining vendor finance with a bank loan to reduce both risk and cost

Option 4: Earn-Outs

An earn-out is a structure where part of the purchase price is contingent on the business meeting agreed performance targets after the sale. Earn-outs typically represent 10–30% of the total purchase price.

When Earn-Outs Make Sense

  • The buyer and seller disagree on the business’s value or future prospects
  • The business is heavily dependent on the owner’s relationships or expertise
  • The buyer wants to manage risk by tying payment to actual performance

Risks

  • Disputes over how performance is measured and calculated are common
  • The seller may resist changes you want to make if they affect earn-out metrics
  • Get your lawyer to draft very specific, measurable, and unambiguous earn-out criteria

Option 5: The SME Guarantee Scheme

One of the most under-utilised financing tools for Australian business buyers. The Australian Government’s SME Guarantee Scheme has supported nearly 109,000 loans worth approximately $16.5 billion as at 30 June 2025 (APRA).

How It Works

  • The Government guarantees up to 50% of the loan, reducing risk for the lender
  • Available to businesses with turnover under $250 million (Recovery Loan Scheme)
  • Maximum loan size: $5 million per borrower, with terms up to 10 years
  • Phase 2 specifically allows use for business acquisition and commercial property purchase
  • Under Phase 2, the maximum is $1 million per borrower

Why It Matters for Business Buyers

Because the Government guarantees half the loan, lenders are more willing to approve applications that might otherwise be declined. This is particularly valuable for buyers who don’t have sufficient property to use as security. Ask your bank or broker specifically about the SME Guarantee Scheme — not all lenders volunteer this option (SprintLaw).

Option 6: Using Home Equity

Many Australian business buyers fund their acquisition by drawing on equity in their residential property. With the RBA cash rate at 3.85% as at February 2026 (RBA), residential mortgage rates remain significantly lower than business loan rates.

How It Works

  • Increase your home loan or take out a separate facility secured against your property
  • Borrow at residential rates (typically 5.5–7% p.a.) rather than business rates
  • Most lenders allow up to 80% LVR before Lenders Mortgage Insurance is required

The Risk

This is the elephant in the room: if the business fails, you risk losing your home. This is a deeply personal decision that depends on your risk tolerance, family situation, and confidence in the acquisition. Always discuss this with a financial adviser and your family before proceeding.

Option 7: Self-Managed Super Funds (SMSFs)

You can use your superannuation to invest in a business through an SMSF, but the rules are strict and the consequences of getting it wrong are severe.

Key ATO Rules

  • Sole purpose test: The investment must genuinely aim to provide retirement benefits — not to support your personal lifestyle or business
  • In-house asset cap: Maximum 5% of total SMSF assets can be invested in related party arrangements
  • Business real property exception: If the SMSF buys commercial property and leases it to a related party, this is exempt from the 5% cap
  • Limited Recourse Borrowing Arrangements (LRBAs): SMSFs can borrow to acquire a single asset, with other fund assets protected from the lender
  • Arm’s length requirement: All transactions must be on commercial terms. Below-market-value transactions may trigger Non-Arm’s Length Income (NALI), taxed at up to 45%

The ATO has been intensifying scrutiny of SMSF investment compliance in 2025–26, particularly around NALI provisions and the sole purpose test. Professional advice from an SMSF specialist accountant and lawyer is essential — not optional (ATO).

Comparing Your Options at a Glance

Financing Method Typical Rate Approval Speed Security Needed Best For
Major bank loan 6.8–8.2% p.a. 21–35 days Property Larger acquisitions with strong financials
Non-bank ADI 7.5–9.5% p.a. 10–18 days Flexible Mid-range deals, less documentation
Fintech lender 9.5–18% p.a. 24–72 hours Often none Smaller deals, speed is critical
Vendor finance 13–17% p.a. N/A (negotiated) GSA over business Can’t get full bank approval
SME Guarantee Scheme Bank rates Varies by lender Reduced (50% govt guarantee) Limited collateral available
Home equity 5.5–7% p.a. 2–4 weeks Residential property Lowest rate, highest personal risk
SMSF N/A Weeks–months SMSF assets Commercial property purchase

Stamp Duty: A State-by-State Consideration

Stamp duty on business purchases varies significantly by state — and many buyers don’t account for it in their budget:

  • NSW: No transfer duty on business asset sales (since 1 July 2016), excluding land and leases
  • Victoria: No stamp duty on business asset transfers (excluding real property)
  • Queensland: Stamp duty applies on dutiable property, with progressive rates up to 5.75%
  • Western Australia: Stamp duty applies, with concessional rates for transactions under $200,000
  • South Australia: No stamp duty on business goodwill or assets
  • ACT: No stamp duty on business assets (excluding real property)
  • Northern Territory: Abolished stamp duty on non-land business assets in May 2023

If you’re buying a business in Queensland or Western Australia, factor this into your financing calculations. Get state-specific advice from your solicitor (No Borders Law Group).

The Interest Rate Environment: What to Know in 2026

The RBA cash rate sits at 3.85% as of February 2026. With 86.9% of outstanding business finance at variable rates (RBA), rate movements have an immediate impact on repayments. Forecasts suggest the cash rate may reach 4.2% by December 2026 if inflation remains above target.

When stress-testing your acquisition finance, model repayments at 1–2% above the current rate to ensure the business can service the debt even if rates rise.

On a positive note for SME borrowers, the spread between SME and large business lending rates is at a historically low level, meaning small business buyers aren’t paying as much of a premium as they have historically (RBA).

The Lending Landscape: A Market in Flux

The numbers tell a story of a rapidly shifting market:

  • Total SME loan stock grew approximately 6.5% year-on-year to mid-2025 — but smaller loans under $1.5 million grew at only 3.5%, suggesting larger deals are driving the growth (RBA)
  • New business loan commitments for property purchase surged 32.9% year-on-year in the December 2025 quarter (ABS)
  • The national average SME loan sits at approximately $147,000
  • Less than 5% of small-sized SME credit is unsecured — meaning most small business lending still requires some form of collateral

Common Financing Mistakes to Avoid

  1. Only budgeting for the purchase price: Forgetting legal fees, stamp duty, working capital, and operational reserves can leave you cash-strapped from day one
  2. Overborrowing: Taking on maximum debt puts enormous pressure on the business, especially during the transition period when revenue may temporarily dip
  3. Not shopping around: The difference between a 7% and 12% interest rate on a $500,000 loan is $25,000 per year. Compare at least three to four lenders
  4. Neglecting working capital: The business needs cash to operate from day one. Budget for at least 3–6 months of operating expenses beyond the purchase price
  5. Settling for the first loan offer: Particularly with fintech lenders, rates and terms can vary enormously. Use a finance broker who specialises in business acquisition lending
  6. Ignoring loan covenants: Read the fine print. Loan agreements often include financial covenants (e.g., minimum debt-service coverage ratios) that, if breached, can trigger default
  7. Skipping professional advice: An experienced accountant and solicitor will save you far more than they cost. This is not the place to economise

Your Next Steps

  1. Get your personal finances in order: Review your credit score, equity position, and savings
  2. Build your professional team: Engage an accountant, solicitor, and finance broker early
  3. Understand the business’s financials: Complete thorough due diligence before committing to any financing
  4. Compare multiple financing options: Don’t default to your existing bank — explore non-bank lenders, the SME Guarantee Scheme, and vendor finance
  5. Stress-test your repayment capacity: Model scenarios with higher interest rates, lower revenue, and unexpected costs
  6. Budget for the full cost: Purchase price + fees + working capital + contingency

Financing a business purchase is complex, but with the right preparation and professional advice, it’s entirely achievable. If you’re looking to buy a business in Australia, browse our current listings or speak with our team to find the right opportunity.

The Complete Due Diligence Checklist for Buying a Business in Australia

Buying an existing business can be one of the most rewarding — and riskiest — decisions you’ll ever make. A landmark study by NYU Stern professors Baruch Lev and Feng Gu, analysing over 40,000 acquisitions across four decades, found that 70–75% of acquisitions fail to deliver their intended value (Fortune, 2024). McKinsey & Company’s own research echoes this: 42% of the time, pre-merger due diligence failed to provide an adequate roadmap for capturing the expected value (McKinsey).

The common thread? Inadequate due diligence. Whether you’re purchasing a café in Melbourne, a trades business in Brisbane, or an NDIS provider in Sydney, the due diligence process is your single biggest safeguard against buying someone else’s problems.

This guide provides a comprehensive, evidence-based checklist tailored specifically for the Australian market — covering every financial, legal, operational, and regulatory area you need to investigate before committing your capital.

What Is Due Diligence, and Why Does It Matter?

Due diligence is the systematic investigation and analysis of a business before you complete a purchase. It’s your opportunity to verify everything the seller has told you, uncover hidden risks, and confirm the business is worth what you’re paying.

According to the KPMG 2025 M&A Deal Market Study, 41% of dealmakers cite completing due diligence as the top obstacle in closing deals — ahead of even agreeing on valuation (44%). This tells us something important: due diligence is hard, it takes time, and the temptation to rush it or cut corners is real.

But the cost of skipping it is far greater. As one Australian advisory firm documented, a seemingly straightforward $6 million acquisition uncovered $600,000 in hidden payroll tax liabilities during due diligence — a discovery that dramatically changed the deal’s economics (Salt Financial Group).

How Long Does Due Diligence Take?

For most small-to-medium business acquisitions in Australia, due diligence takes 30 to 90 days, with 45–60 days being typical for well-organised businesses. More complex transactions — those involving multiple locations, significant employee numbers, or regulatory considerations — may require three months or longer (DueDilio).

Don’t rush this process. The research is clear: Lev and Gu found a “reverse learning curve” in acquisitions, where failure rates have actually increased over time despite growing experience. Overconfidence and time pressure are among the leading culprits (BCG Henderson Institute).

1. Financial Due Diligence

Financial due diligence is where most buyers start — and rightly so. You need to verify that the revenue, profit, and cash flow figures the seller has presented are accurate, sustainable, and not artificially inflated.

Documents to Request

  • Profit and loss statements for the last 3–5 years
  • Balance sheets for the same period
  • Cash flow statements — actual, not projected
  • Business Activity Statements (BAS) — lodged with the ATO for the last 2–3 years
  • Tax returns — business and, if a sole trader or partnership, personal
  • Aged receivables and payables — who owes the business money, and who does the business owe?
  • Debt schedule — all loans, leases, hire purchase agreements, and credit facilities
  • Bank statements — at least 12 months to verify cash flow patterns

Key Questions to Investigate

  • Revenue concentration: Does more than 20–30% of revenue come from a single customer? If so, that customer’s departure could devastate the business. This is one of the most commonly overlooked risks in small business acquisitions.
  • “Adjusted” or “normalised” EBITDA: Sellers often present adjusted earnings that remove personal expenses, one-off costs, and owner salary. Verify every single adjustment independently. What the seller considers a one-off, you may find is a recurring pattern.
  • Working capital trends: Is the business holding more inventory or receivables than it should? This can mask cash flow problems.
  • Seasonality: Understand the seasonal revenue pattern. A business sold during its peak season can look much healthier than its annual average.

2. Legal Due Diligence

Legal due diligence protects you from inheriting disputes, non-compliant contracts, or regulatory problems that could cost you dearly after settlement.

Business Structure and Registration

  • Verify the business’s ABN and ACN through the Australian Business Register
  • Check ASIC records for the company’s registration status, directors, shareholders, and any regulatory actions
  • Confirm the business name registration is current and transferable
  • Understand whether you’re buying via an asset sale or share sale — this has significant tax, liability, and employment law implications

Contracts and Agreements

  • Review all customer contracts — especially any with change-of-ownership clauses that could allow termination on sale
  • Review supplier agreements — are terms favourable? Are there exclusivity arrangements?
  • Review the property lease — this is critical. How long is remaining? Can it be assigned or renewed? What are the rental increase terms?
  • Check for any non-compete or restraint of trade clauses that apply to the seller

Intellectual Property

  • Confirm ownership of trademarks, patents, and domain names
  • Verify the business actually owns (not just licences) any proprietary software, processes, or content
  • Check IP Australia records for registered trademarks

Litigation and Disputes

  • Request disclosure of any current, pending, or threatened legal proceedings
  • Search court records for any history of disputes
  • Check for WorkCover or workers’ compensation claims

3. Tax Due Diligence (Australian-Specific)

Tax due diligence in Australia involves several layers that are unique to our regulatory environment. Getting this wrong can be extraordinarily expensive.

ATO Compliance

  • Verify the business is up to date with BAS lodgements and payments
  • Check for any outstanding ATO payment plans or disputes
  • Confirm PAYG withholding has been correctly calculated and remitted
  • Verify superannuation guarantee obligations have been met — the ATO has significantly increased enforcement in this area

GST Considerations

If you’re buying the business as a going concern, the sale may qualify as GST-free under ATO guidelines. For this to apply:

  • The business must be operating and profitable at the time of sale
  • Both buyer and seller must be registered for GST
  • The sale must include everything needed to continue operating the business
  • The parties must agree in writing that the sale is of a going concern

Capital Gains Tax (CGT)

Sellers will be thinking about CGT — and you should understand the implications too, as they affect negotiation dynamics. Australia offers four small business CGT concessions that may reduce the seller’s capital gain to zero (business.gov.au). These concessions are available when the business has an aggregated turnover under $2 million or net CGT assets under $6 million.

Payroll Tax

Payroll tax is a state-based tax with different thresholds and rates in each state. The $6 million acquisition case study mentioned earlier discovered $600,000 in payroll tax exposure because employees had been misclassified as contractors. Have your accountant specifically investigate contractor vs employee classifications (Salt Financial Group).

Stamp Duty

Transfer duty on business purchases varies by state:

  • NSW: No transfer duty on business asset sales (since 1 July 2016), except for land and leases
  • VIC: No stamp duty on business asset transfers (other than real property)
  • QLD: Stamp duty is payable on certain dutiable property within 30 days of transfer

Always get state-specific advice from your solicitor (LegalVision).

4. Employee and HR Due Diligence

This is an area where Australian buyers are particularly vulnerable — and where many get caught out. The Fair Work Act 2009 (Part 2-8) has specific provisions around the transfer of business that differ significantly from other jurisdictions.

Transfer of Business Provisions

Under the Fair Work Act, a transfer of business occurs when an employee terminates with the old employer and starts with the new employer within three months, performing substantially the same work. When this applies:

  • Personal/carer’s leave balances ALWAYS transfer — there is no option to avoid this
  • Long service leave ALWAYS transfers — it cannot be paid out by the seller and zeroed
  • You may choose whether to recognise prior service for annual leave and redundancy, but you must inform the employee before their employment commences

The Long Service Leave Trap

This is a particularly costly area that NRA Legal describes as “alarmingly common”. When you purchase a business, you inherit employees’ prior service for long service leave purposes. If an employee with eight years of service reaches ten years shortly after you take over, you — not the seller — bear the full long service leave liability. This can amount to over two months’ wages per qualifying employee (NRA Legal).

Other Employment Checks

  • Review all employment contracts and any applicable enterprise agreements or modern awards
  • Check for any underpayment risks — the Fair Work Ombudsman has been increasingly active in enforcement
  • Identify key person dependency — if the business relies on one or two critical employees, what happens if they leave post-acquisition?
  • Review workers’ compensation history and any outstanding claims

5. Operational Due Diligence

Operational due diligence looks beyond the financials to understand how the business actually runs day-to-day. As Zimsen Partners notes, focusing only on financial due diligence is one of the most common mistakes buyers make.

Business Operations

  • Standard operating procedures (SOPs): Are processes documented? Can the business run without the current owner?
  • Owner dependency: How involved is the owner in day-to-day operations, sales, and customer relationships? Small businesses — and 97.3% of Australian businesses are small businesses (ASBFEO) — often have high owner dependency.
  • Supply chain: Are there alternative suppliers? What are the lead times? Are there exclusive agreements?
  • Technology and systems: What software, hardware, and IT infrastructure does the business use? Are licences transferable?

Equipment and Assets

  • Conduct a physical inspection of all equipment, vehicles, and physical assets
  • Verify ownership — search the Personal Property Securities Register (PPSR) for any registered security interests over the business’s assets
  • Check maintenance records and assess the remaining useful life of key equipment
  • Compare the asset register against what’s physically present

Licences and Permits

  • Identify every licence, permit, and registration the business requires to operate
  • Determine whether they transfer automatically or whether you need to apply fresh
  • Check for industry-specific requirements (e.g., liquor licences, food safety, building licences, financial services licences)

6. Commercial and Market Due Diligence

Understanding the business’s market position and competitive landscape is essential for assessing future viability — not just current performance.

  • Customer base analysis: How many active customers does the business have? What’s the retention rate? Is the customer base growing or shrinking?
  • Competitive landscape: Who are the main competitors? What’s the business’s competitive advantage? Is it defensible?
  • Industry trends: Is the industry growing or declining? Are there regulatory changes on the horizon that could impact the business?
  • Online reputation: Check Google Reviews, social media, and industry forums. What do customers say about the business?

7. Cultural Due Diligence

This is often overlooked entirely, but Deloitte’s research found that 30% of M&A integration failures stem from cultural clashes between the acquiring and acquired organisations (Deloitte). Companies that conduct thorough cultural due diligence are 30% more likely to achieve expected synergies.

For small business buyers, cultural due diligence means understanding:

  • How does the current team interact and make decisions?
  • What is the prevailing management style?
  • How will your leadership approach differ, and how might staff respond?
  • Are there informal systems, relationships, or arrangements that aren’t documented?

Red Flags to Watch For

During your due diligence, be especially alert to these warning signs:

  • Seller refuses to provide complete financial records or delays access to information
  • Significant discrepancies between BAS lodgements and reported revenue
  • High employee turnover or multiple recent departures
  • Declining revenue trends that the seller attributes to “temporary” factors
  • Lease expiring soon with no written confirmation of renewal
  • Customer concentration where losing one account would significantly impact revenue
  • Outstanding ATO disputes or unfiled tax obligations
  • The seller is in a rush to close — urgency often masks problems

Your Professional Team

Due diligence is not a DIY exercise. You’ll need, at minimum:

  • Accountant: To verify financials, assess tax implications, and review the business’s financial health (expect $150–$500/hour in Australia)
  • Business lawyer/solicitor: To review contracts, structure the deal, and draft the sale agreement (expect $250–$600/hour)
  • Business broker or adviser: If you’re using one, they can facilitate information exchange and help with valuation
  • Industry specialist: For sector-specific considerations (e.g., a building consultant for a construction business)

Yes, professional fees add up — but they’re a fraction of the cost of buying a business with hidden problems. Think of it as insurance for what may be the largest purchase of your life.

The Bottom Line

With over 370,500 businesses closing their doors in Australia in 2024–25 (ABS), thorough due diligence isn’t just good practice — it’s essential. The 30–90 days you invest in this process could save you hundreds of thousands of dollars and years of stress.

Remember: the seller knows more about their business than you do. Your job during due diligence is to close that information gap as much as possible before you sign. Don’t rush, don’t cut corners, and don’t let excitement cloud your judgement.
