Every chapter before this one has described work. Normalizing earnings and defending the add-back schedule line by line. Researching and tiering a buyer universe. Staging disclosure so a competitor learns nothing it can use. Answering eight diligence workstreams at once without letting the business slip. Holding a runner-up warm while the lead acquirer tests your resolve in week nine. Someone has to do that work, at professional grade, for six to twelve months, while you keep running the company. This final chapter is about deciding who: what representation actually buys you, what it costs and how the fees work, how to interview for it, and, because honesty requires it, when you might reasonably go without it.
The advisor’s view. FIH is a sell-side M&A advisory firm. This chapter recommends a category of service we sell, and we would rather say that plainly than write around it. Our defense is the content itself: the ten questions below will disqualify weak advisors, including us if we cannot answer them, and the section on when you might not need an advisor is genuinely meant. Informed owners who choose well, whoever they choose, make better deals, and better deals are the business we are in.
The Intermediation Spectrum
Sell-side intermediation is not one profession. It spans three broadly different models, and the differences matter far more than the titles, which the industry uses loosely.
Business brokers serve Main Street, generally businesses below roughly $5 million in enterprise value. The model is a listing model: set an asking price, post the opportunity to marketplaces and broker networks, field inbound buyers, and negotiate with whoever shows up. Brokers typically carry many listings at once and are paid almost entirely on commission at close. At that size this is often the right tool; the economics of a small transaction cannot support a bespoke process, and reach matters more than choreography.
M&A advisors and boutique investment banks serve the lower-middle market. The model is a process model, and it inverts the broker’s: no public asking price, no listing. The advisor prepares the company and its materials, approaches a researched buyer universe confidentially, runs competition through indications of interest and letters of intent, and manages diligence and negotiation to close. Teams are small and senior-led, working a handful of engagements at a time rather than dozens.
Middle-market and bulge-bracket investment banks serve larger transactions with deep industry groups, large deal teams, and minimum fees that generally price out companies below the top of the lower-middle market. Prestige is not the issue; attention is. If your company would be the smallest engagement a large bank signs this year, expect the most junior team it fields.
One structural note in a single sentence: when a transaction is structured as a sale of stock or includes rollover equity, securities rules can require the intermediary to hold broker-dealer registration or fit a recognized exemption, so ask any firm you interview how it is registered and how that matches your likely structure.
The spectrum at a glance, with the usual caveat that real firms blur these lines:
| Tier | Typical territory | Model | What you get |
|---|---|---|---|
| Business broker | Main Street, under ~$5M EV | Listing: price it, post it, field inbound | Reach and volume; limited process depth |
| M&A advisor / boutique bank | LMM, ~$5M-$100M EV | Process: prepare, approach confidentially, create competition | Senior attention, curated buyer access, negotiation depth |
| Middle-market / bulge bank | Above the LMM | Process at institutional scale | Industry teams, deep resources; minimums exclude smaller deals |
What Good Representation Actually Does
The right way to evaluate any advisor’s fee is against the counterfactual: what does your process look like without them? Good representation does six jobs, all of which this guide has already described in detail.
Preparation and positioning. Chapter 15’s program, run professionally: the add-back schedule pressure-tested before an acquirer’s QoE team does it (Chapter 6), the story and the numbers assembled into materials an acquirer can underwrite rather than merely read.
Buyer universe access. Knowing which hundred-plus parties to approach and, more valuably, which 20 actually matter for your company: which sponsors are actively building platforms in your sector, which strategics have paid up for what, which family offices never advertise that they acquire at all. Then tiering and sequencing the outreach so competition builds instead of leaking.
Competitive process management. Chapter 10’s machinery: deadlines that are believed, bidders moved in parallel, information staged so leverage is preserved to the LOI and beyond.
Valuation defense through diligence. The number agreed at LOI has to survive Chapter 11. Someone must marshal the data room, answer requests in days rather than weeks, and meet a QoE finding with evidence instead of indignation. This is where unrepresented deals most often bleed value quietly.
Structure fluency. Comparing offers on expected value rather than headline (Chapter 12), and knowing which purchase-agreement terms are worth spending negotiating capital on and which are market (Chapter 13).
Project management and momentum. The least glamorous job and, in our experience, the one that saves the most deals: chasing every open workstream, keeping cadence when fatigue sets in, and delivering the hard messages so the principals’ relationship survives to the closing dinner (Chapter 17).
None of this conjures value that is not there. A good advisor does two things: prevents leakage (a mispriced working capital peg, an unanswered retrade, a tail of one-sided terms) and creates the conditions in which the market can price the company properly. Weak companies do not become strong ones inside a CIM, and any advisor who implies otherwise has told you something useful about their candor.
Fee Structures in Plain Terms
Engagement economics have five moving parts. Understand all five before you sign anything.
Retainers. A monthly work fee or milestone payments during preparation and marketing, commonly credited against the success fee at close. Retainers exist for two legitimate reasons: months of real work happen before any acquirer writes a check, and mutual commitment matters. Be wary of both extremes. A firm that charges nothing up front is often hedging you with volume: sign many mandates, work the ones that get lucky. A firm whose economics live mostly in upfront fees has a weak incentive to close. Token retainers signal weak commitment in both directions.
Success fees. A percentage of transaction value, paid at close, and the heart of the fee. You will hear the Lehman formula and Double Lehman offered as reference points. Both are scaled schedules: a higher percentage on the first tranche of transaction value and progressively lower percentages on the tranches above it. Treat the names as shorthand for “scaled,” not as a market rate. The original schedule dates from another era, every firm quotes its own version, and the actual percentages are negotiated engagement by engagement. Some firms invert the logic with accelerators: a lower base percentage plus a higher rate on proceeds above an agreed threshold, which aligns the advisor with the stretch outcome rather than the easy close. A practical test: ask what the total fee would be at the advisor’s own low case, base case, and stretch case for your company. Alignment lives in the differences between those three numbers.
Minimum fees. A floor on the success fee regardless of final price. Minimums protect the advisor’s economics on smaller transactions, which is fair, but they are also a signal: if the minimum implies a percentage far above the quoted scale at your realistic value, you are below the firm’s true size range and will be staffed accordingly.
Tail provisions. The fee remains payable if the company sells within a defined period after the engagement ends, commonly a year or two, to a party the advisor contacted or introduced. The legitimate purpose is obvious: without a tail, an owner could absorb months of work, terminate, and close directly with a buyer the advisor produced. Watch the scope. A tail limited to contacted parties, with a named list delivered at termination, is fair. A tail covering any sale to anyone is not.
Exclusivity and termination. Sell-side engagements are almost always exclusive, which is reasonable given the investment the advisor makes before any fee is earned. The balancing term is termination: after an initial period, you should be able to end the engagement on reasonable notice. Exclusivity should be earned month by month, not owned.
Common pitfall. Signing the engagement letter without reading the tail. An owner terminates an advisor after a slow year, sells 14 months later to an acquirer the advisor never contacted, and discovers the tail covers any sale, to anyone, for 24 months. The full fee is owed on a deal the advisor did not touch. Negotiate tail scope before signing, when you still have all the leverage.
Then there are conflicts. Ask whether the firm ever takes fees from acquirers, represents buyers in your sector, or has referral arrangements with parties it may introduce. None of these is automatically disqualifying, but every one of them must be disclosed and understood before you sign. The most common conflict, though, is subtler than fee-splitting: it is the valuation used to win your business. Advisors know that the highest number in the room often wins the mandate. Some quote accordingly, then let the market walk you down over the following nine months, by which point you are committed, tired, and anchored to a price that was never real.
Key point. The highest valuation pitch is a pricing strategy, not a price. Quoting a number the market will not pay costs the advisor some future embarrassment; it costs you a year and possibly your best window. Weight the reasoning behind the range far more heavily than the top of it.
Ten Questions to Ask Any Advisor
Interview at least two or three firms, and ask each the same questions.
- “What have you closed at my size, in or near my sector?” Specific, recent, comparable transactions are the evidence. A firm whose deals are all ten times your size, or a tenth of it, is showing you someone else’s credentials.
- “Walk me through your process. What happens in the first 90 days?” Listen for specifics: materials, buyer research, data-room seeding, staging. A vague answer usually means a listing model wearing process language.
- “How would you build the buyer universe for my company, and what access do you have to it?” Push past “our proprietary database.” Which categories of acquirer, which recent conversations, why would they care about you.
- “Who exactly works my deal day to day?” The senior partner who pitches is not always the team that executes. Get the working team by name, and ask what else they are working on.
- “Give me references from closed deals and from processes that did not close.” Dead-deal references show you conduct under stress, which is when representation earns its fee. Refusal to provide them is itself an answer.
- “How is your fee structured, and where exactly are we misaligned?” A good advisor names the misalignments honestly (every success-fee model rewards closing somewhat more than it rewards the last dollar of price). A claim of perfect alignment is a red flag dressed as reassurance.
- “What is your valuation range for my company, and show me the reasoning.” You want a range, the method behind it, and what would move it up or down. Remember the key point above before you reward the biggest number.
- “How many engagements does the firm run at once, and how many is my team on right now?” Senior hours are the actual product. Capacity math is not rude to ask; it is the whole purchase decision.
- “How will you protect confidentiality, especially from competitors?” Anonymous teaser, NDA discipline, staged disclosure, and a clear protocol for when a competitor enters the process (Chapter 10).
- “What do you need from me, and how much of my time will this take?” The honest answer is: a lot. An advisor who promises you will barely notice the process is describing a process you are not really in.
Red Flags
A few patterns should end the conversation regardless of how good everything else sounds. A guaranteed valuation, or “we already have a buyer at this price”: markets are discovered, not promised, and the pre-attached buyer is usually a device for winning the mandate (Chapter 10 explains why the single-buyer path tends to cost money even when the buyer is real). Fee models weighted heavily toward upfront payments, marketing packages, or analysis fees with a thin success component: firms exist whose real product is the upfront fee, and their closing rates reflect it. Generalists at your deal size, in either direction: the storefront broker stretching up to an $8 million EBITDA mandate, or the large bank where you would be the smallest client on the roster. And the absence of verifiable, recent references from live processes at your scale. Owners check references on a $90,000 hire and skip them on the professional handling their largest asset. Do not be that owner.
When You Might Not Need One
Some owners do not need representation, and this section says so plainly.
The true inbound at a full price. If the obvious strategic acquirer, the one any advisor would have called first, approaches you with a demonstrably strong offer, and you have a first-rate M&A attorney and a sell-side QoE firm, negotiating directly can be rational. The fee saved is real. So are the tradeoffs, and you should name them before choosing: you get no market check, so you will never actually know whether the price was full; you have no runner-up kept warm, so retrade discipline weakens the day you sign exclusivity (Chapter 17); and the second-full-time-job problem lands entirely on you (Chapter 10). A middle path exists: some owners engage an advisor on a reduced scope, a valuation perspective or a quiet limited market check, to test the inbound offer without a full process.
Transactions too small for the economics. Below a certain size, an M&A advisor’s minimum fee consumes a painful share of proceeds. A capable business broker, or an attorney-led negotiated sale, may genuinely serve you better. An advisor who takes the mandate anyway, minimum and all, is optimizing for their pipeline rather than your outcome.
The experienced seller. An owner who has sold companies before, or spent a career in deal work, and has real time to commit, can run a credible process. This is rarer than it feels from the inside. For most owners the constraint is not capability; it is attention, and attention is exactly what the business needs most during a sale.
Even in these cases, the trade is the same: you keep the fee and give up competition, market information, and bandwidth. Sometimes that trade is right. Make it deliberately, and make it with a real M&A attorney at your side regardless; of all the professionals in this guide, that one is not optional.
A Note for Acquirers
Buy-side representation exists too, and it is a different product with different economics. Buy-side search firms and advisors source targets, make approaches, and negotiate on behalf of acquirers; fee models vary more widely than on the sell side, mixing retainers, success fees tied to purchase price, and flat or subscription arrangements, so read the alignment as carefully as any owner should. The diligence questions in this chapter transfer almost unchanged: experience at your size and sector, the team that actually works the mandate, references from closed and dead pursuits, and conflicts, especially whether the firm also runs sell-side processes and how it separates the two.

The Bottom Line
- Match the intermediary to your size: brokers run listings, M&A advisors run processes, and large banks carry minimums that exclude most lower-middle-market companies.
- Good representation earns its fee by preventing leakage and creating competition, not by conjuring value that is not there.
- Understand all five fee elements before signing: retainer, success-fee scale, minimum, tail, and exclusivity, with special attention to the tail’s scope.
- The highest valuation pitch is a pricing strategy, not a price; hire the best reasoning in the room, not the biggest number.
- Insist on references from both closed deals and dead ones, and walk away from guaranteed valuations or heavy upfront fees.
- You might not need an advisor for a true full-price inbound or a very small sale, but you give up the market check and the competitive tension either way, and you always need an M&A attorney.
