Selling an advice firm is rarely the clean, single-event transaction that owners imagine when they first contemplate an exit. The headline valuation may look attractive, but the structure surrounding it, deferred consideration, earn-out arrangements, restrictive covenants and post-sale warranties, can materially alter what a seller actually receives, and what their professional life looks like for years afterwards.
When Earn-Outs Leave the Seller Exposed After Selling an Advice Firm
Deferred consideration and earn-outs are now common features of advice-sector transactions. As defined by the ICAEW, an earn-out is a form of deferred consideration in which part of the purchase price is contingent on the business meeting certain performance conditions within a specified period after completion. A buyer may agree a headline figure based on recurring revenue or assets under advice, but only a portion of that consideration is payable on the day documents are exchanged. The balance follows, sometimes over two or three years, once pre-agreed targets are met.
According to Advisor Legacy, common earn-out metrics include revenue, EBITDA, gross profit and client retention. Each of those measures can be influenced, whether directly or indirectly, by decisions the buyer makes after completion: staffing structures, client charging models, integration into a wider group, or central cost allocations. A seller who previously controlled every significant operational decision may find that a substantial portion of their proceeds depends on choices made by somebody else entirely.
This is where the drafting detail becomes critical. Sellers need to understand precisely what metric is being measured, what changes the buyer is contractually permitted to make during the earn-out period, and what protections apply if the acquired business is reorganised or absorbed into a larger structure. The headline price may attract the attention; the conditions under which it is paid deserve equal scrutiny.
Restrictive Covenants, Warranties and the Hidden Costs of Completion
Earn-outs are not the only mechanism that extends a seller’s exposure beyond completion. Restrictive covenants are a standard feature of advice-firm acquisitions, and their scope can be broader than sellers anticipate. A buyer paying for longstanding client relationships and accumulated goodwill will typically seek restrictions preventing the seller from approaching former clients, soliciting employees or establishing a competing business for a defined period. For an owner planning to retire, such clauses may carry little practical weight. For someone who expects to remain professionally active, they can materially narrow the options available.
The detail matters considerably: which clients are covered, what activities are restricted, what geographical scope applies, and how long the restriction runs. A seller who accepts a lower price on the expectation of launching another venture within a year needs to satisfy themselves that the proposed covenants permit that plan. These provisions are not boilerplate; they form part of the economics of the transaction.
Share purchase agreements in FCA-regulated firms typically carry warranties covering regulatory compliance, client complaints, employment matters, contracts, accounts, tax and litigation. Indemnities may also be required where due diligence identifies a specific known risk, with the seller agreeing to bear the financial consequences if that risk crystallises after completion. A successful warranty or indemnity claim can reduce the net value the seller retains from the deal. Sellers should pay close attention to the limitations on any such liability: the financial cap, the time limits for bringing claims, the minimum thresholds, and the procedural steps the buyer must follow. Disclosure during due diligence is not merely an obligation to the buyer’s lawyers; it is often a seller’s most practical protection after completion.
There is also the personal dimension. Advice businesses remain relationship-driven, and buyers often require founders to remain involved through a transition period, whether as an employee, under a consultancy arrangement, or against defined milestones. An entrepreneur accustomed to autonomous decision-making may find themselves reporting to new management, with remuneration and responsibilities set out in a separate agreement. Before signing, sellers should be clear about their expected working days, their authority, who they report to, and what happens to any outstanding consideration if the working relationship deteriorates.
Gareth Fatchett, a partner at FS Legal, argues that a sale should be assessed as a complete package. A higher headline valuation accompanied by an uncertain earn-out, onerous restrictions and three years of mandatory involvement may, in practice, represent a less favourable outcome than a lower figure with greater certainty and a cleaner departure. Owners spend years building a business and thinking about what it might eventually be worth. The structure of the exit deserves the same careful attention.
