Heads of terms when selling an accountancy practice

Heads of terms record the agreed deal in writing before lawyers draft the sale agreement. They are your last chance to shape the terms before you agree to deal with one buyer only.

Why heads of terms matter

  • They get both sides agreed before lawyers draft the full sale agreement
  • They bring any deal-breakers to light early, when they cost little to resolve
  • They record protections for staff and clients before exclusivity begins
  • Clear, fair heads make the rest of the deal and the completion smoother

Once both sides are serious, the deal is captured in heads of terms (also called a term sheet or heads of agreement). The formal sale agreement is drafted from it. Agree the points that matter most to you at this stage, before you grant the buyer exclusivity and while you could still talk to someone else. Some clauses bind you as soon as you sign, and two others need particular care.

What heads of terms cover

Price
The number and exactly how it's calculated (e.g. multiple of GRF, with the fee base defined)
Structure
Cash on completion vs deferred vs any earn-out — and the timing of each tranche
Deal type
Share sale or asset sale — it drives your tax, so decide deliberately
Timeline
Target completion date and the length/shape of the handover
Your involvement
Clean break, or a phased step-down — for how long, doing what, and paid how
People & clients
What happens to staff (TUPE) and how client relationships are transitioned
Conditions
What must be true to complete (satisfactory diligence, consents, etc.)
Exclusivity
A period in which you won't negotiate with other buyers
Confidentiality
How the process — and the fact of it — stays private
Warranties (outline)
The broad shape of the assurances you'll give in the final agreement

What's binding and what isn't

Most of the commercial terms (price, structure) are usually a statement of intent, firmed up in the sale agreement after diligence. But several clauses are typically legally binding even at heads-of-terms stage, so read them carefully:

The non-binding terms still matter. The sale agreement is drafted from what the heads say, and changing a term later is possible but costs goodwill and slows the deal.

Two clauses that need the most care

The first is what happens to staff and clients after completion. If their continuity matters to you, say so here, in writing, so that it is part of the deal from the start. The second is how any deferred consideration is protected: how it's calculated, when it's paid, and what happens if the buyer's own actions affect it. Agree both before you sign the heads and grant exclusivity; see earn-outs and deferred consideration and the tax treatment.

Practical tips

Heads of terms come after initial due diligence and lead into the formal agreement and completion.

Frequently asked questions

Ask your own question →

Are heads of terms legally binding?

Mostly not — the commercial terms (price, structure) are usually a statement of intent firmed up later. But specific clauses, typically confidentiality, exclusivity and costs, are usually binding, so read and take advice before signing.

What should heads of terms include when selling a practice?

Price and how it's calculated, deal structure and timing, whether it's a share or asset sale, the timeline, your ongoing involvement, what happens to staff and clients, completion conditions, exclusivity and confidentiality.

What's the most important thing to get into heads of terms?

The protections that are hard to claw back later: how staff and clients are treated, and exactly how any deferred or contingent consideration is calculated and protected. Agree these before you sign the heads and grant exclusivity.

Should I sign heads of terms without a lawyer?

It's wise to take advice first. Even though most terms are non-binding, the binding clauses (exclusivity, confidentiality, costs) carry real obligations, and a clear heads makes the whole deal smoother.
