A Purchase Offer Letter (also known as a Letter of Offer or Expression of Interest) is a document issued by a prospective buyer to a vendor setting out the buyer's non-binding interest in acquiring a business, assets, property, or shares at an indicative price and on proposed terms. In Australia, Purchase Offer Letters are commonly used in business acquisitions, commercial property transactions, and other significant commercial dealings as a preliminary step before the parties commit to negotiating and executing a formal binding Sale Agreement.

As a general rule, a Purchase Offer Letter does not create a binding obligation on either the buyer or the vendor to complete the proposed transaction. It is a preliminary document that records the buyer's interest and proposed terms, subject to the satisfactory completion of due diligence, the negotiation and execution of a formal Sale Agreement, and the fulfilment of any specified conditions. The document signals that the buyer is serious about the proposed acquisition and provides the vendor with enough information to decide whether to engage further.

However, it is important to note that some provisions of a Purchase Offer Letter are typically intended to be legally binding — most importantly, an exclusivity clause (preventing the vendor from negotiating with other buyers during the due diligence period) and a confidentiality clause (protecting the confidentiality of information disclosed during the evaluation process). These binding provisions should be clearly identified in the letter to avoid uncertainty.

In Australian commercial practice, a Purchase Offer Letter is often the first formal step in a business acquisition process, preceding a Heads of Agreement or Term Sheet and the formal Sale Agreement. It allows both parties to quickly assess whether there is a sufficient basis for proceeding with more detailed negotiations before incurring substantial legal and advisory costs.

This template is governed by Australian federal and state law and is suitable for use in all Australian states and territories including New South Wales, Victoria, Queensland, Western Australia, South Australia, Tasmania, the Australian Capital Territory, and the Northern Territory.

A Purchase Offer Letter is appropriate whenever a prospective buyer wishes to formally indicate their interest in acquiring a business, assets, property, or shares in Australia, and to propose indicative terms for that acquisition, before committing to a fully negotiated binding agreement.

You need a Purchase Offer Letter when you are: submitting a preliminary bid for a business or business assets that are being sold through a structured sale process; expressing serious interest in acquiring a privately held business from its owner; responding to a business broker's information memorandum by submitting a formal offer; initiating acquisition discussions with a vendor who has indicated they are open to selling; or establishing a due diligence and exclusivity framework before committing to full legal negotiations.

A Purchase Offer Letter is particularly valuable where: the acquisition process is competitive and the buyer wishes to formally register their interest and proposed terms; the buyer needs the vendor to grant exclusivity during the due diligence period to justify the cost of that investigation; the buyer and vendor wish to record their preliminary understanding before incurring substantial legal fees negotiating a full Sale Agreement; or the parties wish to establish confidentiality obligations to protect commercially sensitive information disclosed during the evaluation process.

While a Purchase Offer Letter is not a substitute for a formal binding Sale Agreement, it provides important commercial and legal benefits: it demonstrates the buyer's seriousness and commitment to the process; it gives the vendor sufficient confidence to grant exclusivity and commit resources to the sale process; it establishes a framework for due diligence and subsequent negotiations; and it records the key proposed commercial terms so that the parties can quickly identify any fundamental disagreements before investing heavily in legal documentation.

Both parties should seek independent legal advice before signing a Purchase Offer Letter, particularly where the letter includes binding provisions such as an exclusivity clause or confidentiality obligations.

A well-drafted Australian Purchase Offer Letter should include several key elements to clearly communicate the buyer's interest and proposed terms, and to appropriately protect both parties during the preliminary phase of the acquisition process.

The non-binding declaration is the foundation of any Offer Letter and should clearly state that the letter does not constitute a legally binding offer or contract, and that no binding obligations to complete the transaction arise unless and until a formal Sale Agreement is executed. This declaration should also identify which specific provisions of the letter (such as exclusivity and confidentiality) are intended to be legally binding notwithstanding the non-binding nature of the letter as a whole.

The indicative price clause sets out the buyer's proposed purchase price for the target, noting that it is an indicative, non-binding price subject to satisfactory due diligence and the negotiation of the formal Sale Agreement. The clause should also describe the proposed payment structure — for example, whether the price will be paid as a lump sum at completion, as an earn-out based on future performance, or as structured payments over time.

The conditions clause identifies the key conditions precedent to which the proposed transaction is subject. Common conditions in an Australian business acquisition include: satisfactory completion of due diligence; receipt of finance approval; execution of the formal Sale Agreement; and receipt of any required regulatory or third-party consents (such as landlord consent for lease assignment).

The due diligence clause specifies the buyer's proposed due diligence period and the information and access that the vendor must provide. For a business acquisition, this should include access to financial records, material contracts, employee information, licences, and PPSR information.

The exclusivity clause — if included as a binding provision — prevents the vendor from negotiating with or providing information to other potential buyers during the exclusivity period. This is a critical protection for the buyer who is incurring costs in conducting due diligence.

The confidentiality clause ensures that the existence and terms of the proposed transaction, and all information disclosed during the evaluation process, are kept confidential by both parties. This provision should expressly survive the lapse or termination of the Offer Letter.

The acceptance deadline specifies the date by which the vendor must accept the Offer Letter. After this date, the letter lapses and the buyer is no longer bound by its terms.
