Letters of Intent vs Heads of Terms in Australian Business Sales: Which Do You Need?

You've received an offer for your business. The buyer's lawyer sends over a "Letter of Intent" asking you to sign immediately to "lock in the deal." Your lawyer counters with a "Heads of Terms" instead. The buyer insists they're the same thing. Your lawyer says they're completely different. Who's right? The confusion between Letters of Intent (LOI) and Heads of Terms (HOT) causes more failed business sales than almost any other documentation issue—because sellers don't understand what they're actually committing to when they sign.

What's the Difference? LOI vs HOT

In Australian M&A practice, Letters of Intent and Heads of Terms are similar but distinct documents that outline the preliminary agreement between a buyer and seller before the formal sale contract. The terms are often used interchangeably—and that's where the confusion (and problems) begin.

Letter of Intent (LOI)

A Letter of Intent is typically a one-way expression of interest from the buyer to the seller, stating:

• The buyer's intention to purchase the business
• Proposed purchase price and deal structure
• Key commercial terms (payment method, conditions, etc.)
• Indicative timeline and next steps

Key characteristic: LOIs are usually drafted by the buyer and sent to the seller as an opening proposal. They tend to be less formal and more focused on expressing serious interest rather than negotiating detailed terms.

Heads of Terms (HOT)

A Heads of Terms (also called Heads of Agreement or Term Sheet) is a bilateral document that represents a negotiated agreement between buyer and seller on the key deal terms:

• Purchase price and structure (cash, shares, earnout, etc.)
• Assets/shares being acquired
• Conditions precedent (due diligence, financing, regulatory approval)
• Exclusivity and break fees
• Timeline and process milestones
• Binding vs non-binding provisions

Key characteristic: HOTs are negotiated documents signed by both parties, representing a mutual agreement on commercial terms before legal documentation begins.

The Practical Difference

Real-world usage: In practice, Australian M&A advisors often use Heads of Terms as the preferred document because it's more robust, negotiated, and provides clearer process governance. However, many buyers (especially overseas or inexperienced buyers) will submit a Letter of Intent first, which sellers should treat as an opening proposal—not a final agreement.

Are LOIs and HOTs Legally Binding?

This is the #1 source of confusion and the reason sellers get trapped in bad deals.

The General Rule: Non-Binding on Commercial Terms

Both LOIs and HOTs are generally non-binding on the commercial terms (price, structure, etc.). This means:

• The buyer is not legally obligated to complete the purchase
• The seller is not legally obligated to sell at the stated price
• Either party can walk away without penalty (subject to binding clauses—see below)

Why non-binding? Because both documents are signed before full due diligence. The buyer hasn't yet verified your financials, legal compliance, or operational details—so they can't commit to a binding purchase. Similarly, you haven't verified the buyer's financing or ability to close—so you shouldn't be locked in either.

⚠️ BUT: Certain Clauses Are ALWAYS Binding

Even though the overall agreement is non-binding, specific clauses in both LOIs and HOTs are always binding, including:

1. Confidentiality

The buyer's obligation to keep your business information confidential is legally enforceable, regardless of whether the deal proceeds.

2. Exclusivity (No-Shop / No-Talk)

If you agree to an exclusivity period (e.g., 60 days), you are legally prohibited from:

• Soliciting other offers (no-shop)
• Negotiating with other buyers (no-talk)
• Providing information to competing bidders

Critical risk: If you sign an LOI or HOT with a 90-day exclusivity clause and the buyer drags their feet, walks away on day 89, you've lost 3 months of market time and may have missed better offers.

3. Break Fees / Termination Fees

Some HOTs include a break fee payable if:

• The seller accepts a competing offer during the exclusivity period
• The seller withdraws without valid reason

Example: "$50,000 payable to the buyer if the seller terminates negotiations or accepts a third-party offer within 60 days."

4. Cost Coverage

Some agreements specify who pays for due diligence, legal fees, or transaction costs if the deal fails. This is binding.

5. Governing Law and Jurisdiction

Clauses specifying Australian law (e.g., NSW or VIC) and dispute resolution are binding.

How to Identify Binding vs Non-Binding Clauses

A well-drafted LOI or HOT will include a section titled "Binding and Non-Binding Provisions" that explicitly states:

"Non-Binding Provisions: Except as expressly stated below, this Heads of Terms is not legally binding and does not create any obligation to proceed with the transaction."

"Binding Provisions: Notwithstanding the above, the following clauses are legally binding and enforceable: Clauses 7 (Confidentiality), 8 (Exclusivity), 9 (Costs), and 12 (Governing Law)."

Red flag: If the document doesn't clearly specify which clauses are binding, you're at risk of accidentally creating a binding contract you didn't intend to sign.

What Should a LOI or HOT Include?

Whether you're receiving a Letter of Intent or negotiating Heads of Terms, these are the essential elements that should be covered:

1. Parties and Target Business

• Full legal names of buyer and seller
• Business name, ABN, and legal structure (Pty Ltd, Trust, etc.)
• Description of what's being sold (shares vs assets)

2. Purchase Price and Structure

• Headline price: e.g., $2,500,000
• Payment method: Cash at completion, vendor finance, earnout, share consideration
• Adjustment mechanism: Completion accounts, locked box, or working capital adjustment
• Allocation: If asset sale, breakdown by asset class (important for tax)

3. Deal Structure

• Share sale vs asset sale
• Entities involved (buyer SPV, holding companies, etc.)
• Tax structure considerations (if material)

4. Conditions Precedent

What must be satisfied before the deal can complete:

• Satisfactory due diligence
• Buyer financing approval
• Regulatory approvals (FIRB, ACCC if applicable)
• Third-party consents (landlord, key suppliers, franchisors)
• No material adverse change (MAC clause)

5. Exclusivity and Standstill

• Exclusivity period: e.g., 60 days from signing
• No-shop: Seller won't solicit other offers
• No-talk: Seller won't engage with competing buyers
• Standstill: Buyer won't approach seller's employees, customers, or suppliers during negotiations

Negotiation tip: Sellers should push for the shortest exclusivity period possible (30-45 days) and include a sunset clause that automatically terminates exclusivity if the buyer doesn't meet milestones (e.g., complete due diligence by day 30).

6. Due Diligence Access

• What information will be provided (data room, site visits, management meetings)
• Timeline for due diligence completion
• Seller's obligation to cooperate reasonably

7. Confidentiality (Binding)

• Buyer's obligations to protect confidential information
• Non-solicitation of employees
• Return of documents if deal fails

8. Timeline and Process

• Key milestones (due diligence, draft SPA, completion)
• Target completion date
• Long-stop date (deal terminates if not completed by this date)

9. Costs and Expenses

• Each party bears their own legal and advisor costs (standard)
• Who pays for specific due diligence (e.g., environmental reports)
• Break fee (if applicable)

10. Binding vs Non-Binding Statement

Explicit statement of which clauses are binding (as discussed above).

11. Governing Law and Dispute Resolution

• Jurisdiction (e.g., New South Wales)
• Dispute resolution process (mediation, arbitration, or court)

When to Use LOI vs HOT

Use a Letter of Intent When:

• Early-stage indication: The buyer wants to express serious interest but hasn't completed initial due diligence
• Informal negotiations: You're in preliminary discussions and want to test buyer appetite before engaging lawyers
• Speed matters: You want to quickly gauge whether the buyer's price range is realistic
• Auction process: You're running a competitive process and want non-binding initial bids from multiple parties

Seller approach: Treat a buyer's LOI as an opening proposal, not a commitment. Don't grant exclusivity based on an LOI alone—insist on negotiating a full Heads of Terms first.

Use Heads of Terms When:

• Serious negotiations: Both parties are committed and want to formalize key commercial terms before instructing lawyers
• Complex deals: The transaction involves earnouts, vendor finance, or other structures that need detailed agreement
• Granting exclusivity: You're willing to give the buyer exclusive access, but only after key terms are agreed
• Managing process: You want a clear roadmap with milestones, timelines, and obligations

Best practice: In any significant business sale, Heads of Terms should be the default. They provide better protection, clearer process governance, and reduce the risk of miscommunication.

Common Mistakes Sellers Make

1. Signing Without Reading the Binding Clauses

You think it's "just a non-binding LOI," so you sign quickly—only to discover you've granted 90-day exclusivity and agreed to a $100,000 break fee if you withdraw.

Solution: Always have your lawyer review LOIs and HOTs before signing, even if they seem informal.

2. Granting Exclusivity Too Early

A buyer sends an LOI with a compelling price, and you immediately grant 60-day exclusivity. The buyer then uses that time to chip away at the price during due diligence, knowing you can't talk to other buyers.

Solution: Only grant exclusivity after the buyer has completed preliminary due diligence and confirmed their offer in a detailed Heads of Terms.

3. Accepting Vague Terms

The LOI says "Purchase price subject to completion accounts adjustment" but doesn't define the methodology. You later discover the buyer expects a $300,000 working capital deduction you never agreed to.

Solution: Insist on specific terms in the HOT: exact adjustment methodology, working capital target, earnout calculation formulas, etc.

4. No Sunset Clause on Exclusivity

You grant 60-day exclusivity, but the buyer drags due diligence to day 59, requests an extension, then terminates on day 75. You've lost 2.5 months of market time.

Solution: Include a sunset clause that automatically terminates exclusivity if the buyer doesn't meet milestones (e.g., complete due diligence by day 30, exchange SPA by day 50).

5. Assuming "Subject to Contract" Means You Can Walk Away Free

Many LOIs and HOTs include the phrase "subject to contract" or "subject to execution of formal sale agreement," which sellers assume means they can walk away anytime. However, if you've signed binding exclusivity or break fee clauses, you can't walk away without penalty during that period.

Solution: Understand that "subject to contract" only applies to the commercial terms (price, structure), not the process terms (exclusivity, confidentiality, costs).

LOI vs HOT: What's Best for Australian Sellers?

If you're selling a business in Australia, the best practice is:

1. Receive buyer's Letter of Intent: Treat it as an opening proposal. Review the price and structure, but don't sign anything binding yet.
2. Counter with a detailed Heads of Terms: If the LOI is acceptable in principle, engage your lawyer to draft a comprehensive HOT that protects your interests (limited exclusivity, clear milestones, no break fees unless justified).
3. Negotiate the HOT: Ensure all key commercial terms are clear and agreed before signing.
4. Grant limited exclusivity only after HOT is signed: Typically 30-45 days, with sunset provisions tied to buyer performance.
5. Move to Sale and Purchase Agreement (SPA): Once due diligence is complete and the buyer confirms their commitment, instruct lawyers to draft the formal SPA based on the agreed HOT.

Key Takeaways

• LOIs are buyer proposals; HOTs are negotiated agreements. Treat them accordingly.
• Both are generally non-binding on commercial terms—but specific clauses (exclusivity, confidentiality, break fees) are always binding.
• Never grant exclusivity without a detailed Heads of Terms that locks in key deal terms and protects your process.
• Shorter exclusivity periods (30-45 days) with sunset clauses protect you from buyers who stall or chip.
• Always have a lawyer review before signing, even if the document looks informal.

Final Thoughts

The difference between a Letter of Intent and Heads of Terms may seem academic, but in practice, how you handle preliminary agreements can make or break your deal. Sellers who rush into exclusivity based on a vague LOI often find themselves trapped with a buyer who drags their feet, re-trades the price, or walks away after tying up the business for months.

The best approach? Use LOIs as conversation starters, but insist on robust Heads of Terms before granting any exclusivity or binding commitments. Your future self—and your sale price—will thank you.
