Start with the contract's definition of transaction value
A seller comparing advisers may focus on the quoted success-fee percentage. The larger difference can sit in the amount to which that percentage applies. A fee based on cash paid to shareholders is not necessarily the same as a fee based on transaction value that includes debt, retained ownership or future payments. Ask each adviser to calculate its proposal against the same illustrative deal structure.
Read the definition with transaction counsel. Identify the assets or interests covered, the transactions that trigger a fee and every component included in the base. A business sale, partial investment, joint venture or later transaction may receive different treatment. Do not infer the scope from a heading that simply says success fee.
A historical 2011 SEC-filed advisory engagement illustrates the importance of detail: it defines transaction value broadly, describes tiered fees and specifies a partial retainer offset. Those are terms of that particular engagement, not current market rates or a recommended contract. The useful lesson is to obtain equally explicit calculations for the proposal in front of you.

Bridge the headline deal to the seller's closing cash
Assume an invented transaction has $25 million of enterprise value and $5 million of debt that is settled as part of the transaction, leaving $20 million of equity consideration. Assume that consideration consists of $17 million cash to the sellers and $3 million of rollover ownership. This simplified bridge excludes cash adjustments, working-capital changes, taxes and other deal costs.
If a hypothetical adviser charges 2% on a contractually defined $25 million base, the fee is $500,000. If another charges 2% solely on the $17 million closing cash, the fee is $340,000. The difference is $160,000. Neither fee base should be assumed from the word value; the engagement must establish it.
Under the first assumed fee, $17 million of closing cash less $500,000 leaves $16.5 million before the other excluded items. Do not subtract the $5 million debt again from that amount: it was already reflected in the bridge from enterprise value to equity consideration. Equally, the $3 million rollover is not cash available to pay a fee due at closing.
Apply tiered rates to the correct portions
A tier schedule can apply a different marginal rate to successive slices of value, or it can operate in another explicitly defined way. Ask the adviser for a numerical example that crosses each threshold. The labels alone may not establish whether the last rate applies only to the excess or to the entire transaction.
For illustration, assume a fee of 4% on the first $5 million, 2% on the next $15 million and 1% on value above $20 million. On a $25 million fee base, the three portions are $200,000, $300,000 and $50,000. The total is $550,000. Applying the final 1% rate to all $25 million would produce $250,000 and misread these assumed marginal terms.
Include any minimum fee, cap or separate payment for a particular service in the same reconstruction. Test a smaller transaction and a changed structure as well as the expected deal. Management should understand the amount payable if the eventual sale is below the initial target, rather than discovering the minimum after months of work.
| Illustrative value slice | Marginal rate | Fee |
|---|---|---|
| First $5 million | 4% | $200,000 |
| Next $15 million | 2% | $300,000 |
| Remaining $5 million | 1% | $50,000 |
| Total $25 million | Defined tier schedule | $550,000 |
Keep retainers and expense reimbursements visible
Determine which payments are earned regardless of completion and which reduce the success fee. If $60,000 of retainers already paid is fully creditable against the illustrative $550,000 success fee, the additional closing payment is $490,000 and total advisory fees remain $550,000. Adding the retainers again would double count them.
If only half of those retainers is creditable, the closing payment is $520,000 and total fees become $580,000. That $30,000 difference comes from the credit provision, not the percentage schedule. Record the exact condition for receiving the credit, including whether it applies to all covered transaction types and within the relevant engagement period.
Ask separately about reimbursable expenses, outside specialists and approval limits. The seller may owe certain costs even if the transaction is abandoned. Keep those commitments in the transaction budget and cash forecast rather than presenting the contingent fee as the entire potential expenditure. Any tax treatment should be assessed by the relevant adviser using the actual arrangement.
Match payment triggers to uncertain consideration
Deferred payments, holdbacks and earnouts can complicate the fee schedule. Ask whether the adviser is paid on an estimated amount at closing, on the maximum contractual amount, when the seller receives cash, or under another method. Determine who establishes any valuation of noncash consideration and how a later change is treated.
Consider a specific downside: the seller never receives an expected contingent payment. The model should show whether the fee already paid changes under the agreement or remains due. Do not build a refund into the forecast because it seems reasonable; confirm that the contract provides it and how it would operate.
Review multiple closings and post-termination obligations with counsel. A later payment can create a fee event after the original sale process has ended. Identify the covered parties, period and transaction boundaries without assuming that every introduction creates a permanent entitlement. The purpose of this analysis is to make the proposed obligations understandable before they become a dispute.
Compare the service and the incentive together
A complete comparison shows the work included, responsible team, fee base, calculation, cash dates and costs if no sale occurs. Ask whether valuation work, buyer outreach, negotiation support, diligence coordination and any separate opinion are included or separately scoped. A lower fee may cover a narrower assignment, while a higher fee does not establish better execution.
Discuss how the payment structure relates to the seller's goals, including timing, certainty and noncash consideration. The company and its advisers should assess conflicts and applicable qualification or regulatory requirements for the proposed work. This fee exercise does not determine who is legally permitted to arrange a particular transaction.
Retain the worked examples with the signed engagement and update them when the transaction structure changes. The SBA emphasizes careful planning and a reviewed agreement when selling a business. Extending that discipline to the adviser's compensation lets the seller see the amount left after fees and the obligations that remain if the deal evolves.
