Evaluate advisors before a process is already moving
Advisor selection affects preparation quality, buyer access, confidentiality, negotiation discipline, and closing certainty. The best time to assess those questions is before a mandate is signed and before sensitive information has been shared widely.
Use this guide to compare incentives, senior involvement, sector judgment, process design, and the practical work an advisor will perform. A strong advisor should help shareholders make better decisions, not simply introduce counterparties.
The selection process should also test how an advisor behaves when the answer is not obvious. A serious advisor should be willing to discuss timing, alternatives to a full sale, and situations where waiting may protect more value than launching a process too early.

The main fee components
Most M&A advisory engagements include a retainer and a success fee. The retainer compensates the advisor for preparation and active process work before closing. The success fee is payable only if a transaction closes and is usually calculated as a percentage of transaction value or equity value, depending on the engagement letter. Some advisors also include a minimum success fee, expense reimbursement, and a fee tail covering buyers introduced during the engagement who transact after termination.
- Monthly or fixed retainers for preparation and process work.
- Success fees payable at closing, often tiered by transaction value.
- Minimum fees for smaller or more complex engagements.
- Expense reimbursement for travel, data room costs, research, or third-party services where agreed.
Typical success fee structures
For lower mid-market transactions, success fees often fall in the low single-digit percentage range, with higher percentages on smaller transactions and lower percentages on larger transactions. A tiered structure may increase the advisor's percentage above a threshold price, aligning incentives around exceeding a baseline valuation rather than merely closing any deal.
The correct structure depends on size, complexity, expected buyer universe, and the amount of work required before buyers are approached. A business with complex add-backs, multiple shareholder groups, international buyers, or regulatory considerations may require more preparation than a clean, straightforward company sale.
What owners should read carefully
The engagement letter matters. Owners should understand whether the fee is based on enterprise value or equity value, whether debt assumed by the buyer counts toward the fee base, how rollover equity is treated, whether earnouts are charged when paid or at closing, and how long the fee tail lasts. None of these points is inherently wrong, but they should be explicit before the engagement begins.
- Fee base: enterprise value, equity value, or another agreed measure.
- Treatment of seller notes, earnouts, retained equity, and contingent payments.
- Length and scope of any tail period after termination.
- Termination rights, exclusivity, and reimbursement obligations.
Why the cheapest fee can be expensive
An advisor who charges less but runs a thin process can cost shareholders far more than the fee difference. Missing the right strategic buyer, approaching buyers without adequate preparation, mishandling confidentiality, or failing to manage a re-trade can reduce proceeds by multiples of the advisory fee. The economic question is not simply what the advisor charges; it is whether the advisor can improve price, certainty, structure, and closing probability enough to justify the cost.
How to evaluate value for money
Owners should ask for a clear work plan, senior team involvement, buyer strategy, views on valuation drivers, and examples of how the advisor manages difficult diligence or negotiation issues. A credible advisor should be able to explain how they protect leverage, how they decide which buyers to approach, and how they compare offers when headline price is not the only variable. Fee discipline matters, but it should be assessed alongside capability and fit.
