Heads of agreement when buying a business
General information, not financial, tax or legal advice. Have your own lawyer read a heads of agreement before you sign it.
A heads of agreement is a short document that records the main terms a buyer and seller have agreed in principle, before the full contract of sale is drafted. This guide treats it as the same step Business Queensland calls a letter of intent. Whether any part of it binds you is a question for your lawyer, so have them read it before you sign. Business Queensland describes a letter of intent as something that should be non-binding and come before a final contract1.
What it usually records
Business Queensland says a letter of intent sets out the proposed terms and conditions of the purchase and plans the timing of the sale. It can include a lock-out or exclusivity period to help negotiations.1 It should state whether the offer is subject to a trial, finance or a satisfactory lease.1
In a business sale, the terms worth getting onto one page early are:
- The price and how it is paid.
- What is included: the assets, the stock, the lease, the name.
- The conditions that must be met before the sale goes ahead, such as finance, due diligence and the landlord agreeing to assign the lease.
- Training and handover after settlement.
- A restraint on the seller starting a competing business.
- The deposit, and when it is returned.
- The settlement date.
Business.gov.au lists the sale price, payment method, handover, restraint clauses and any conditions both sides must meet as things a business sale agreement sets out.2 Its section on negotiating the sale lists the deposit amount (usually 10% of the sale price) among the things to agree.2 A heads of agreement is where you agree them in outline. The contract is where they become exact.
Is a heads of agreement legally binding?
Do not assume either way from the name on the document. Business Queensland says a letter of intent should be non-binding, and says a letter of offer, the next step, is a legally binding document that sets out the final price, terms and conditions of sale.1
So read the wording, not the title, and ask your lawyer what it means. You may want most of the document to be an outline of a deal still to be negotiated, and a few clauses to bind from the day it is signed: confidentiality, exclusivity (the seller will not negotiate with anyone else for a set period) and who pays the costs. Ask your lawyer to say plainly, in the document itself, which clauses bind and which do not. A sentence such as "this clause is binding" next to each one removes the guesswork.
Heads of agreement or contract of sale
The two do different jobs.
- The heads of agreement records the deal in principle, so both sides can test whether they are really agreed before paying for a full contract.
- The contract of sale is the full, legally binding agreement. Business.gov.au says a business sale agreement is a legally binding contract between buyer and seller.2
Business Queensland sets out the order: a letter of intent, then a letter of offer, then a purchase contract drafted with your advisers once the offer is accepted.1 It adds that all purchase contracts include conditions for both seller and buyer.1 Business Queensland's page is Queensland's guide. If the business is in another state, ask your lawyer what applies there.
Before you sign one
- Have your own lawyer read it. Business.gov.au suggests getting a legal professional to draw up the sale contract, and Business Queensland says to consult your advisers before signing any agreement.21
- Do not pay a deposit you cannot get back unless you know the conditions it depends on. If finance, due diligence or the lease fails, the document should say what happens to the money.
- Do not treat it as a reason to skip checking the business. Business.gov.au says to gather as much information as you can on the business before you sign the contract.3 See due diligence when buying a business.
- Make the conditions match your plan. If you need a loan, say the offer is subject to finance; see finance to buy a business. If the seller is lending part of the price, see vendor finance.
- Be careful with exclusivity. A lock-out period stops the seller talking to other buyers, which suits you, but check the clause does not tie you to the deal for longer than your checks need.
If a broker is handling the sale, ask them for their template and send it to your lawyer; see choosing a business broker.
