You've found a buyer. The price is broadly agreed. Everyone is cautiously optimistic. Then someone mentions the Heads of Agreement, and the room gets a little quieter.

For many SME owners, this is the first time they've encountered the document. It sounds formal, possibly binding, and a little unclear in its purpose. That uncertainty is worth addressing directly — a Heads of Agreement is one of the most consequential documents in a business sale, and misunderstanding it at this stage can cost you time, money, or the deal itself.

This article explains what a Heads of Agreement covers in an Australian business sale, which clauses are legally binding and which aren't, and what to expect in the weeks after you sign one.

What Is a Heads of Agreement?

A Heads of Agreement — sometimes called a Letter of Intent or Memorandum of Understanding — is a preliminary document that records the key commercial terms both parties have agreed to before a formal Sale and Purchase Agreement is drafted.

It is not the final contract. Think of it as a structured handshake: it confirms that buyer and seller are aligned on the fundamentals, and gives both parties a solid basis for moving into due diligence and legal documentation with confidence.

In Australian SME transactions, a Heads of Agreement typically runs between two and six pages. It's shorter and less detailed than the final contract, but it carries real weight in setting expectations and protecting both sides during the gap between agreement in principle and settlement.

What a Heads of Agreement Covers

The specific content varies by deal, but most Heads of Agreement in an Australian business sale address the following areas.

Purchase Price and Payment Structure

This is the central term. The document records the agreed price and how it will be paid. Payment structures in SME sales often combine a cash component at settlement with a vendor finance arrangement, an earnout tied to future performance, or both. Getting this in writing early prevents misalignment from quietly compounding during due diligence.

Assets and Liabilities Included in the Sale

A business sale can be structured as an asset sale or a share sale. The Heads of Agreement should specify which assets are included — plant and equipment, stock, goodwill, intellectual property, customer lists — and which liabilities, if any, the buyer is taking on. Ambiguity here is one of the most common sources of disputes later in the process.

Conditions Precedent

These are the conditions that must be satisfied before the sale can proceed. Common examples include satisfactory completion of due diligence, landlord consent to a lease assignment, franchisor approval, or financing sign-off from the buyer's lender. Each condition should have a clear timeframe attached.

Exclusivity Period

Most Heads of Agreement include an exclusivity clause preventing the seller from negotiating with other buyers for a defined period — typically thirty to sixty days. This gives the buyer confidence to invest in due diligence without the risk of being outbid while they work. For sellers, it's worth understanding exactly what you're giving up during this window, and making sure the period isn't open-ended.

Confidentiality Obligations

Even in a preliminary document, confidentiality clauses are typically binding. Both parties agree not to disclose the existence or terms of the proposed transaction to third parties. This matters significantly for sellers who haven't yet told their staff, suppliers, or customers that the business is on the market.

Deposit

Some Heads of Agreement include a deposit payable by the buyer on signing, held in trust until settlement or returned if conditions aren't met. Not every deal includes this, but where it appears, the terms governing its release should be clearly stated.

Transition and Training

In owner-operated businesses, buyers often need the seller to remain involved for a period after settlement — to transfer relationships, operational knowledge, and supplier contacts. The Heads of Agreement may outline the expected duration and nature of this handover, even if the precise terms are finalised in the main contract.

Which Parts Are Legally Binding?

This is the question most sellers ask, and the answer requires some care.

In Australia, a Heads of Agreement is generally not a binding contract for the sale itself. The purchase isn't complete until a formal Sale and Purchase Agreement is executed and all conditions are satisfied. However, certain clauses are typically drafted to be immediately binding. These usually include:

  • Confidentiality obligations
  • The exclusivity period
  • Any deposit arrangement
  • Costs provisions (who pays legal fees if the deal falls over)

The non-binding sections — price, asset schedule, and the like — remain subject to change during due diligence and legal drafting. That said, walking away from agreed commercial terms without good reason can damage trust and, in some circumstances, expose a party to a claim for misleading or deceptive conduct under the Australian Consumer Law.

Have a solicitor review the Heads of Agreement before you sign. The document looks simple. The implications aren't always.

What Happens After You Sign

Signing a Heads of Agreement marks the beginning of the formal transaction process — not the end of negotiation. Here's what typically follows.

Due Diligence

The buyer will conduct a detailed review of the business: financial statements (usually three years of accounts), tax returns, lease agreements, employment contracts, supplier arrangements, and any pending legal matters. The depth of due diligence varies by deal size and complexity, but in a business valued between $500,000 and $5 million, expect the process to take three to six weeks.

Sellers should prepare for this phase before signing the Heads of Agreement. Having clean, organised financial records and a data room ready reduces delays and signals to the buyer that the business is well run.

Once due diligence is complete and both parties are satisfied, solicitors draft the formal Sale and Purchase Agreement. This document incorporates everything agreed in the Heads of Agreement, plus the detailed terms that due diligence has clarified or modified. Warranties, indemnities, restraint of trade clauses, and settlement mechanics are all addressed here.

Final Negotiations

Price adjustments or additional conditions emerging from due diligence are common. A buyer who discovers that a key supplier contract isn't transferable, or that equipment maintenance has been deferred, may seek a price reduction or a specific warranty. This is normal. How these conversations are managed often determines whether the deal actually closes.

Settlement

Settlement is when ownership transfers. Funds are released, keys change hands, and the transition period begins. For sellers, it's the moment the entire process has been building toward. For buyers, it's the start of a new chapter of operational responsibility.

Common Mistakes at the Heads of Agreement Stage

Several errors come up regularly in SME transactions at this point. Being aware of them can protect you.

Treating it as purely informal. Because the document is preliminary, some sellers sign without legal review. The binding clauses — particularly exclusivity and confidentiality — can have real consequences if you haven't understood what you've agreed to.

Agreeing to an open-ended exclusivity period. If due diligence drags on and there's no defined end date or extension mechanism, you may find yourself locked out of other conversations indefinitely.

Leaving the asset schedule vague. "The business and all associated assets" isn't sufficient. A clear, itemised list of what is and isn't included prevents disputes when the Sale and Purchase Agreement is being drafted.

Not preparing for due diligence before signing. The period between signing the Heads of Agreement and completing due diligence is when many deals fall over. Sellers who can't produce clean records quickly give buyers reasons to doubt the business — or to renegotiate.

How We Support Sellers Through This Process

At Everest Commercial Property & Business Brokers, we work with sellers through every stage of a transaction, including the Heads of Agreement phase. We don't hand you a document and leave you to manage it alone.

Our end-to-end approach means the same team that conducted your business appraisal and prepared your information memorandum is also coordinating due diligence and working alongside your solicitor during legal documentation. No handoffs between advisers, no gaps in institutional knowledge, no moments where you're explaining your business from scratch to someone new.

For cross-border buyers — particularly those from Asia-Pacific markets — we manage the additional complexity that comes with international transactions: language, documentation standards, and the specific considerations that arise when a buyer is navigating an Australian acquisition from overseas.

Confidentiality is managed as a process throughout. NDAs are in place before any detailed information is shared, and information is released in stages as the transaction progresses. Your staff, customers, and suppliers don't need to know the business is for sale until you're ready for them to know.

Frequently Asked Questions

Is a Heads of Agreement legally binding in Australia?
Not in its entirety. The document as a whole is generally not a binding contract for the sale. However, specific clauses — typically confidentiality, exclusivity, and deposit terms — are drafted to be immediately binding. Have a solicitor review it before you sign.

Can I negotiate after signing a Heads of Agreement?
Yes. The Heads of Agreement records agreed commercial terms in principle. Negotiations continue during due diligence, and it's common for adjustments to be made before the formal Sale and Purchase Agreement is executed.

What is a typical exclusivity period in an Australian business sale?
Most exclusivity periods in SME transactions run between thirty and sixty days. The period should have a defined end date and, ideally, a mechanism for extension by mutual agreement if due diligence is progressing well.

What happens if the buyer walks away after signing a Heads of Agreement?
If the buyer withdraws without satisfying a condition precedent — such as due diligence approval — they're generally entitled to do so under the terms of the document. If they withdraw without valid reason, the seller may have recourse depending on how the document is drafted. This is another reason legal review before signing matters.

Does a Heads of Agreement need to be witnessed or notarised?
In most Australian SME transactions, no. However, requirements can vary depending on the nature of the assets involved and whether any real property is included in the sale. Your solicitor will advise.

What is the difference between a Heads of Agreement and a Sale and Purchase Agreement?
A Heads of Agreement records the key commercial terms agreed in principle before due diligence. A Sale and Purchase Agreement is the formal, legally binding contract that transfers ownership of the business — longer, more detailed, and drafted after due diligence is complete.

How long does it typically take to go from Heads of Agreement to settlement?
In a straightforward SME transaction, the period from signing the Heads of Agreement to settlement is usually eight to sixteen weeks. Complex deals — those involving lease assignments, franchise approvals, or cross-border buyers — can take longer.

What to Do Now

A Heads of Agreement is a significant milestone. It means a buyer is serious and the transaction has moved from conversation to process. How you manage the weeks that follow determines whether that process ends at settlement or falls apart before it gets there.
