Vendor Due Diligence In Australia: What Small Business Sellers Need

Thinking about selling your business or bringing on an investor? One of the smartest steps you can take is vendor due diligence (sometimes called VDD).

Instead of waiting for a buyer to dig through your records and find issues, you get ahead of the process, fix problems proactively and present a clean, credible picture of your business.

This guide explains what vendor due diligence is, why it helps small business sellers, what to include in your checklist, and how to run the process step-by-step in Australia.

What Is Vendor Due Diligence (And Why It Helps Small Business Sellers)?

Vendor due diligence is a seller-led review of your business before you go to market. You gather key documents, assess legal and commercial risks, and tidy up any gaps so buyers have confidence in what they’re purchasing.

It’s the difference between showing a buyer a stack of files and presenting a well-organised data room with clear answers to their questions. Done right, it can speed up the sale, reduce renegotiations and protect your sale price.

For many owners, this means getting help to run a tailored legal and commercial review. If you need a structured process and documentation, our Legal Due Diligence Package is designed for small business transactions.

When Should You Do Vendor Due Diligence?

Start 4-12 weeks before you approach buyers or brokers.

The earlier you start, the more time you have to fix issues (for example, updating contracts or registering trade marks) without the pressure of a live deal.

What Do Buyers Look For? Your Vendor Due Diligence Checklist

Every deal is different, but most buyers ask similar questions. Use this checklist to prepare your documents and answers in advance.

1) Corporate Structure & Ownership

• Company details, ACN/ABN, current ASIC company extract, and corporate registers.
• Shareholder details, option holders and any rights that affect a sale (drag, tag, pre-emption). If there are multiple founders, ensure you have an up-to-date Shareholders Agreement covering decision-making and sale mechanics.
• Company Constitution and any special resolutions relevant to a sale.

2) Financial & Tax

• Audited or accountant-prepared financial statements (last 2-3 years) and management accounts YTD.
• Tax returns, BAS, GST registrations and evidence of compliance.
• Any government grants, loans or vendor finance arrangements; if applicable, confirm terms for any Vendor Finance Agreement.

3) Material Contracts & Customers

• Top customer and supplier agreements, key terms (pricing, termination, assignment/change-of-control).
• Standard customer terms and SOWs, plus renewal/churn data if relevant.
• Any exclusivity, distribution, or reseller arrangements. Prepare a list of contracts that need counterparty consent if there’s a change of control.

4) Employment & Contractors

• Organisation chart, key employee roles, salaries, incentive plans and leave balances.
• Signed Employment Contracts and any contractor agreements (including IP assignment and confidentiality clauses).
• Policies (workplace conduct, WHS) and evidence of Fair Work compliance.

5) Intellectual Property & Brand

• Trade marks, business names, domains, copyrights and proprietary software/assets. Register any brand assets early via Register Your Trade Mark.
• Assignment deeds for IP created by employees/contractors.
• Any licences-in or licences-out (e.g. software, images, content).

6) Privacy, Data & Cyber

• Current Privacy Policy, collection notices and consents for personal information.
• Data maps, security policies, breach logs, and vendor risk assessments.
• Customer communications about data use or marketing (unsubscribe records, cookie consents).

7) Regulatory, Licences & ACL

• Industry licences, permits and registrations (and renewal dates).
• Australian Consumer Law compliance (claims, refunds, warranties) and any complaints or ACCC correspondence.
• Website and marketing claims aligned with the ACL’s rules against misleading conduct.

8) Property, Leases & Equipment

• Real property ownership or commercial leases (including options and rent reviews) and landlord consent requirements.
• Equipment registers, maintenance records and warranties.

9) Litigation, Insurance & Disputes

• Current or threatened disputes, demand letters, and settlement deeds.
• Insurance policies (public liability, product, professional indemnity, cyber) and recent claims history.

10) Assets, Security Interests & The PPSR

• Asset registers and serialised assets (vehicles, plant).
• List of third-party security interests and releases. Expect buyers to check the Personal Property Securities Register-review our guide on what the PPSR is and ensure you can deliver assets “free and clear”.

How To Run Vendor Due Diligence Step-By-Step

Step 1: Define Scope And Deal Structure

Decide whether you’re preparing for a full sale, partial exit, or capital raise. Identify whether you’ll pursue an asset sale or share sale (more on this below). This defines which records matter most and which consents you’ll need.

Step 2: Assemble Your Core Team

Nominate an internal coordinator and line up your accountant and lawyer. Your legal team can help prioritise fixes and prepare sale-ready documents like the Business Sale Agreement so you can move quickly when a buyer appears.

Step 3: Build A Clean, Secure Data Room

Organise documents into logical folders that mirror the checklist above. Control access, track versions and maintain a single source of truth.

Before you grant access to external parties, require a signed Non-Disclosure Agreement and watermark sensitive documents. Limit downloads where possible.

Step 4: Fix Issues Proactively

Prioritise “value-impact” fixes that buyers commonly query, such as missing signatures on contracts, unregistered IP, or privacy compliance gaps.

Examples include updating template agreements, formalising contractor IP assignment, registering your core brand with a trade mark, or refreshing your Privacy Policy to reflect how you actually collect and use data.

Step 5: Prepare A Vendor Due Diligence Report (Optional)

For some deals, a concise vendor due diligence report summarising what was reviewed (and any mitigations taken) can build buyer confidence and reduce repetitive questions. Your lawyer can help strike the right balance between clarity and limiting your representations.

Step 6: Control Q&A And Disclosures

Nominate a single point of contact for buyer questions and keep answers consistent. If a contract needs consent to assign, or a licence requires notice, flag it early and prepare a clear plan for obtaining approvals.

Step 7: Keep It Current

Deals can take time. Keep your data room updated with new contracts, financials and board approvals as they arise. Out-of-date documents cause delays and erode trust.

Common Red Flags To Address Early

• Unregistered or unclear IP ownership (fix with assignment deeds and a trade mark application).
• Customer contracts that prohibit assignment or change of control (map consents and prepare a communication plan).
• Privacy and marketing consents that don’t match actual practices (align your Privacy Policy and collection notices with reality).
• Missing or inconsistent Employment Contracts and outdated policies (roll out updated documents before the sale process).
• Unreleased PPSR registrations from old lenders or suppliers (obtain releases so assets can transfer cleanly).

Asset Sale Vs Share Sale: What Changes In Vendor Due Diligence?

Your diligence focus will shift depending on whether the buyer acquires the shares in your company (share sale) or the business assets and liabilities you agree to transfer (asset sale).

• Share sale: The buyer steps into the company “as is”, including all contracts, employees, and potential liabilities. Expect deeper reviews of historical compliance, taxes, HR and disputes. See our overview of a Share Sale vs Asset Sale to understand the implications.
• Asset sale: Only specified assets and contracts move across, often requiring assignments and landlord consents. Focus more on identifying which assets are transferring, ensuring clear title, and mapping all required third-party approvals.

In both cases, your vendor due diligence should feed directly into the sale documents, disclosure letter, and completion deliverables to avoid surprises at the finish line.

What Legal Documents Should You Prepare?

Every transaction is unique, but most small business sales rely on a core set of documents. Having these ready (and accurate) can save weeks:

• Business Sale Agreement: Sets out the assets and liabilities being transferred in an asset sale, price, warranties, restraints and completion steps. Start drafting your Business Sale Agreement early so it reflects your deal structure.
• Share Sale Agreement: For a share sale, this governs the transfer of shares, purchase price adjustment, warranties, and post-completion obligations. If you’re weighing structures, revisit the Share Sale vs Asset Sale considerations as part of your document strategy.
• Non-Disclosure Agreement: Protects your confidential information during buyer due diligence. Use a robust, mutual Non-Disclosure Agreement when multiple bidders may be involved.
• Privacy Suite: Ensure your Privacy Policy and collection notices match your practices-buyers will check this closely.
• Employment Contracts & Policies: Up-to-date Employment Contracts and clear policies reduce risk and smooth employee transfers.
• IP Assignments & Trade Marks: Confirm ownership via assignment deeds and formal protection (for example, through Register Your Trade Mark).
• Disclosure Letter & Completion Deliverables: Tie your data room and Q&A to formal disclosures and plan for itemised handover steps (keys, codes, PPSR releases, landlord consents). Your team can align these with a practical completion checklist.

Key Takeaways

• Vendor due diligence helps you get “sale ready” by fixing issues before buyers find them, protecting value and speeding up the process.
• Organise a focused checklist covering structure, contracts, HR, IP, privacy, licences, property, disputes and PPSR so your data room answers the big questions.
• Start early, assemble your team, require NDAs, and keep everything current-consistency builds buyer confidence.
• Expect deeper historical reviews in a share sale; in an asset sale, map transfers and consents carefully so nothing critical is left behind.
• Prepare core documents upfront-NDA, sale agreement, employment terms, IP and privacy-to minimise delays and renegotiations.
• Link your diligence to formal disclosures and completion steps so the deal signs and completes smoothly.
