The adviser’s payment on a completed sale, normally a percentage of the price. What counts as "the price" is worth pinning down: whether deferred amounts, earnouts and assumed debt are included changes the fee materially.
Why it matters
A success fee is the payment an adviser earns for actually closing a sale, and on the surface it
is the fairest kind of fee there is: nothing is owed unless the seller gets a deal. That alignment
is real and worth valuing. It is also not the whole story, because a success fee is usually
expressed as a percentage, and a percentage of what turns out to be a genuinely contested
question.
Sellers who read the mandate closely at signing, rather than at closing, are the ones who are not
surprised by the number on the final invoice. Sellers who skip that step find out what "the
price" means on the day they can least afford to argue about it — with a buyer already signed and
an adviser holding the leverage of having just delivered the deal.
This is also the one clause in the mandate that most closely resembles a fee model any reader may
already recognize from elsewhere in M&A — a percentage on completion is the same shape as a
success-fee model GetDeal itself uses, described below without spin.
How it works
A success fee has two parts that each deserve separate attention: the rate, and the base it is
applied to.
The rate. Usually a single percentage, sometimes a sliding scale that steps down as the
price rises (or up, to reward an adviser for pushing past an agreed floor). There is no
meaningful "typical" rate to quote here — engagement size, sector, and the amount of work a
sale actually requires all move it, and any number given without those specifics would mislead
more than it informs. What matters is that the rate is the easy part of the negotiation; the
definition of the base is the hard part and the one sellers skip.
The base — "the price." A headline number rarely equals the number the fee is calculated
against. Worth pinning down explicitly, before signing:
- Does it include deferred consideration — an earnout or a
seller note — or only cash paid at closing? - Does it include assumed debt the buyer takes on, which inflates enterprise value without
putting a matching amount of cash in the seller's pocket? - Does it include escrow amounts held back, which the seller may never actually receive in
full? - Is it calculated on enterprise value or equity value, and which adjustments move
between the two?
Each of those changes the fee owed, sometimes substantially, and each is a real point of
disagreement that has come up in real deals before yours. Writing the definition down while both
sides are still cooperative is far cheaper than litigating it after the wire transfer.
When it is owed. Almost always on completion, not on signing an offer or a term sheet — a
signed letter of intent that falls apart in diligence should not trigger a fee for work that
produced no sale. Check that the trigger is completion, and check what happens if the deal
completes in stages rather than in one transaction.
What to watch for
Do not let "success fee" and "the fee is fair" collapse into the same sentence. The rate can
be entirely reasonable and the base can still be defined in the adviser's favor. Read the two
separately.
A rate that steps down at higher prices can cut against your interests in a specific way.
If the adviser earns proportionally less on the marginal dollar above a threshold, their
incentive to keep pushing for a better price weakens exactly when your leverage is highest. Check
whether the scale steps up or down, and understand which one you are agreeing to.
"Enterprise value" is not "what lands in my account." A seller who is quoted a fee on
enterprise value but receives equity value net of debt and adjustments can end up paying a
percentage of money that never reached them. Ask for a worked example with real numbers before
you sign, not after the deal is priced.
A success fee with no completion trigger is not a success fee. If the mandate lets the
adviser earn the fee — or a large break fee — on a signed term sheet that later collapses, you
are paying for effort, not for success, no matter what the clause is called.
Compare against the retainer credit. If the mandate includes a retainer
credited against the success fee, confirm the credit is actually reflected in the final invoice,
not just promised in the contract text.
On GetDeal
GetDeal charges its own success fee, and it is worth stating plainly rather than glossing over:
the fee is owed only on a completed sale — nothing is charged for listing a company, for being
matched with investors, or for conversations that do not lead anywhere. The arrangement is
non-exclusive, so working with GetDeal does not mean signing away the right to pursue other
routes in parallel, and the fee is capped rather than open-ended.
The specifics — the percentage, and what counts as "the price" for the purpose of calculating it
— are set in the engagement letter, so those are worth putting directly rather than inferring.
The section above is the list to ask about.
Sellers who work with GetDeal under a mandate get an Engagement view showing aggregate progress
on the work, updated as it happens, and a deal room with a fee panel that shows exactly what
would be owed on completion — the same "what is 'the price'" question this page raises, answered
concretely for your own deal rather than left as a clause to interpret. The Playbook lays out
which stage triggers which obligation, so the completion trigger described above is something
you can see rather than take on faith.

Questions people ask
- What is a success fee in an M&A mandate?
- It is the payment an adviser earns when a sale actually completes, usually calculated as a percentage of the price. Nothing is owed if no sale happens, which is what makes it different from a retainer, and the incentive it creates is straightforward: the adviser is paid for delivering a closed deal, not simply for working on one.
- Why does the definition of "price" matter for a success fee?
- Because a headline sale price and the number a fee is calculated against are often different figures. Deferred payments, assumed debt, and amounts held in escrow can all be included or excluded from the base the fee applies to, and each choice changes what the seller actually owes. Pinning the definition down before signing avoids a dispute at closing.
- Is a lower success fee rate always the better deal for a seller?
- Not necessarily. A lower rate applied to a broadly defined price base, including deferred and contingent amounts, can cost more than a higher rate applied to cash received at closing only. The rate and the base have to be read together, since either one alone tells an incomplete story about what will actually be owed.
- Does GetDeal charge a success fee?
- Yes, and it is charged only when a sale completes, never for listing a company or for introductions that do not lead to a deal. The arrangement is non-exclusive and the fee is capped rather than open-ended, with the specific rate set in the engagement letter and the amount owed shown in the deal room as the process moves toward completion.
