Due Diligence Checklist For Buying A Business In Australia

Buying a business in Australia can be a smart way to step into entrepreneurship with an existing brand, customer base and revenue. But before you sign a contract, it’s essential to make sure the business is exactly what it appears to be.

That’s where due diligence comes in. Think of it as a full health check on the business you’re about to buy. It helps you verify the numbers, understand the risks and make confident decisions when negotiating your deal.

In this guide, we’ll walk through what due diligence actually involves, a practical checklist you can use, common red flags, how to use your findings to shape the deal, and the key legal documents you’ll likely need. We’ll keep it practical, Australian and focused on helping you move forward with confidence.

Important note: this guide focuses on legal and commercial due diligence. Tax implications (for example GST, stamp duty or purchase price allocations) can be complex and depend on your structure and the deal terms. It’s a good idea to get advice from your accountant or tax adviser alongside the legal work.

What Is Due Diligence When Buying A Business?

Due diligence is the process of investigating a business before you buy it. You’re checking whether the information you’ve been given is complete and accurate, and whether there are any issues that could affect value or your ability to run the business after settlement.

In practice, that means reviewing financial records, contracts, employees, assets, intellectual property, licences and regulatory compliance. You’re also confirming that key assets can transfer to you and that you won’t inherit unexpected liabilities.

Done properly, due diligence reduces risk, supports financing, and gives you leverage to negotiate a fair price and sensible contract protections. If you prefer expert support, engaging a legal due diligence specialist can streamline the process and help you spot issues early.

Due Diligence Checklist: What To Review In Australia

Every business is different, but most buyers in Australia should work through the following key areas. Use this as a starting point and tailor it to the business, industry and deal structure (asset sale vs share sale).

1) Legal Structure, Ownership And Right To Sell

• Structure and registrations: Confirm whether you’re buying assets or shares, and check the entity’s ABN, ACN (if a company), GST status and business name registrations.
• Ownership and authority: Make sure the seller actually owns what you’re buying and has authority to sell it. If there are co-owners or secured parties, you’ll need the right consents and releases.
• Security interests: Search the PPSR to see if lenders or suppliers have registered security over equipment, stock, vehicles, domain names or other key assets that need to be discharged before settlement.

2) Financial Records And Cash Flow

• Financial statements: Review profit and loss, balance sheet and cash flow statements (typically for the last 2–3 years), plus BAS and tax returns. Look for consistency between financials and bank statements.
• Debtors and creditors: Check debtor and creditor ageing reports to understand working capital needs and whether customers are paying on time.
• Liabilities: Identify loans, ATO payment plans, guarantees, contingent liabilities, unusual accruals or off-balance sheet exposures.
• Normalisation: Consider what revenue and costs will look like under your ownership (for example, owner’s wages, related-party rent, or one-off expenses).

3) Contracts, Customers, Suppliers And Premises

• Customer and supplier agreements: Review term, pricing, exclusivity, minimums, termination rights and assignment clauses. Watch for any “change of control” provisions that could allow termination on a sale.
• Key concentration: Assess whether a small number of customers or suppliers drive a significant share of revenue or inputs, and whether those relationships will continue after settlement.
• Premises: If the business trades from a site, review the lease terms, options and rent reviews. If it’s a retail business in NSW, make sure the lease aligns with the Retail Leases Act and confirm you can obtain the landlord’s consent to an assignment.
• Other commercial contracts: Consider distribution, white-label, reseller, software licences, payment gateways and any third-party platform terms that the business relies on.

4) Employees, Contractors And Workplace Compliance

• Employee list and contracts: Obtain a schedule of employees, roles, pay rates, leave balances, service periods and any special arrangements. Check Award coverage, superannuation and payroll practices.
• Transfer of employees: Understand which employees you’ll be taking on, and how accrued entitlements will be treated and adjusted in the purchase price.
• Contractors: Review contractor agreements and consider the risk of misclassification. If you’re retaining staff, ensure each person has a compliant Employment Contract going forward.
• Disputes: Ask for details of any current or threatened workplace complaints, underpayment claims or investigations.

5) Assets, Stock And Intellectual Property

• Plant and equipment: Verify condition, maintenance records, ownership (not leased or financed unless assigned) and serial numbers. Confirm all assets are included in the sale schedule.
• Inventory: Check stock levels, age, valuation method and slow-moving items. Agree how stock will be counted and priced at settlement.
• Brand and IP: Confirm ownership of business names, logos, domains, social handles, website content and any registered trade marks. Consider whether to register your trade marks before or shortly after completion to protect the brand.
• Data and systems: Review CRM, POS, software licences, website CMS and any integrations. Ensure you’ll have transferable rights and that customer data practices meet privacy requirements.

6) Licences, Approvals And Legal Compliance

• Industry licences: Identify any activity-specific licences (for example, food, liquor, health, childcare, NDIS) and whether they are transferable or need to be re-applied for.
• Consumer law: Review advertising, refund policies and standard form contracts for compliance with the Australian Consumer Law. Pay close attention to misleading or deceptive conduct and unfair terms, including obligations under section 18.
• Privacy: If the business collects personal information, ensure there’s a compliant Privacy Policy, appropriate consents and secure data handling practices.
• Environmental and safety: For regulated industries or premises with equipment, confirm compliance with workplace health and safety and any environmental permits.

7) Insurance And Disputes

• Insurance: Review current policies (public liability, professional indemnity, cyber, property, workers compensation) and claims history. Plan your own cover from completion.
• Litigation and disputes: Ask for details of any current, threatened or historical disputes, regulatory notices or claims involving the business or its owners.

Tip: a structured review led by a lawyer can save time and help you focus on the risk areas that matter most. If you want support, consider engaging a legal due diligence expert to coordinate the legal, contract and compliance checks alongside your accountant’s financial review.

Red Flags To Watch For

You won’t always find major issues, but the following red flags should trigger deeper questioning, stronger contractual protections, a price adjustment or, in some cases, walking away.

• Revenue spikes or expense cuts right before the sale that don’t match underlying activity.
• Heavily concentrated revenue among a few customers, or key contracts that can’t be assigned or terminate on change of control.
• Leases close to expiry, no option to renew, or landlord unwilling to consent to an assignment.
• Security interests over critical assets that the seller can’t (or won’t) discharge in time for settlement - especially PPSR registrations from lenders or suppliers.
• Unregistered brand assets (no trade mark protection) where the brand is central to value, or evidence of potential IP infringement.
• Workplace compliance gaps, underpayment risks or unresolved HR issues that could become costly after completion.
• Licences that aren’t transferable, or a history of non-compliance with regulators.
• Missing SOPs, weak handover plans or inability to access essential systems and data post-sale.

If something doesn’t add up, ask for more information and get advice. It’s far easier to fix risks, price them in, or adjust the deal terms before you sign than after settlement.

How To Use Your Findings In The Deal

Due diligence is only useful if you act on what you learn. Here’s how buyers typically use their findings:

• Structure the deal: Decide whether an asset sale or a share sale better manages risk, tax and transferability of key contracts and licences.
• Negotiate the price: Adjust for items like aged stock, capital expenditure needed to bring equipment up to scratch, or customer churn risk.
• Add protections: Build in warranties and indemnities that match the actual risks you’ve identified, and tailor escrow, retention or price holdbacks if needed.
• Condition the contract: Include conditions precedent for critical items - such as landlord consent, key customer assignments, licence approvals, PPSR releases and finance approval - so you’re not forced to complete if they don’t happen on time.
• Plan the handover: Agree on a realistic transition plan, including training, introductions to key customers and suppliers, and access to systems.

Cooling-off periods generally don’t apply to business sale contracts in Australia. If you want time to complete checks, negotiate a due diligence period or specific conditions precedent in your agreement. That way, you can proceed, renegotiate or exit based on objective milestones rather than relying on a statutory cooling-off right that likely doesn’t exist for this kind of transaction.

Negotiation Examples

• Unassignable contract: If a key supplier contract can’t be assigned, require the seller to secure a new contract on equivalent terms before completion or agree on a price reduction.
• Undischarged security: If the PPSR search shows a lender’s charge over equipment, make discharge and proof of release a condition to completion and hold back part of the price until it’s confirmed.
• Brand risk: If trade marks aren’t registered, require the seller to cooperate with filings and provide warranties that the brand doesn’t infringe others’ rights.

What Legal Documents Will You Need?

The exact documents depend on your industry and whether you’re buying assets or shares. However, most Australian business purchases will involve some or all of the following:

• Business Sale Agreement: The core contract setting out the price, assets included/excluded, completion mechanics, conditions precedent, warranties, indemnities and restraint of trade. Ensure it clearly lists what you’re buying (for example, equipment, IP, stock, contracts) and how liabilities are handled. If you need a robust template tailored to your deal, consider a dedicated Business Sale Agreement.
• Non-Disclosure Agreement (NDA): Signed before you receive sensitive information, an NDA helps protect the seller’s confidential information and your own discussions during negotiations.
• Lease Assignment And Landlord Consent: For leased premises, you’ll usually need landlord consent and formal assignment documents. Build timing for approvals into your conditions precedent.
• Intellectual Property Assignment: Deeds to transfer trade marks, domain names, business names, social media and other IP, plus warranties that the seller is the owner.
• Employment Documents: New or updated Employment Contracts and workplace policies for employees you’re taking on, plus deeds dealing with the transfer of service and entitlements as agreed in the sale contract.
• Customer Terms And Supplier Agreements: Where you’re resetting relationships post-sale, ensure you have clear modern agreements (for example, service terms, distribution or supply agreements) to manage risk going forward.
• Privacy And Data: If you’re acquiring customer databases or operating online, make sure the business has a compliant Privacy Policy and appropriate data transfer and consent arrangements.

It’s common to include transitional assistance obligations in the sale agreement (for example, a few weeks of owner support to train you and introduce key customers and suppliers). Make sure the scope, timing and any fee for that support are clearly stated.

Practical Tips For A Smoother Process

• Use a document checklist: Ask the seller to provide a structured data room with financials, contracts, licences, asset lists and HR documents indexed for review.
• Stage your review: Tackle high-impact issues first (premises, key contracts, licences, security interests) so you can make early calls on feasibility.
• Coordinate advisers: Keep your lawyer and accountant aligned so financial normalisations and legal risk allocation complement each other.
• Lock in the timeline: Put realistic dates in the contract for due diligence, finance and third-party consents, with the ability to extend if approvals take longer than expected.

Key Takeaways

• Due diligence is your pre-purchase health check - verify the numbers, confirm ownership and transferability of assets, and identify risks before you commit.
• Work through a tailored checklist covering structure and PPSR searches, financials, contracts and leases, employees, assets and IP, licences, privacy and insurance.
• Watch for red flags like unassignable key contracts, security interests that won’t be released, brand/IP gaps, compliance issues and unrealistic performance trends.
• Use your findings to shape the deal: price adjustments, targeted warranties and indemnities, and conditions precedent for critical approvals and releases.
• Cooling-off periods don’t usually apply to business sale contracts - negotiate a due diligence period and specific conditions in your Business Sale Agreement.
• Protect your position with the right documents, including an NDA, IP assignments, lease consents, Employment Contracts and a compliant Privacy Policy.
• Get coordinated legal and accounting advice - tax and legal settings interact and can materially change the best way to structure and document your purchase.
