Most owners selling a business end up paying four or five different advisors, and almost nobody explains up front which one does what. A business exit advisor is the person who runs the sale process end to end: they prepare the business for diligence, build the buyer list, manage the bidding, and hold the deal together through close. Around that person sit a transaction attorney, a CPA or tax advisor, a valuation specialist, and often a capital advisor who handles the financing side of the deal. Knowing which seat does which job is the difference between paying for one process and paying for it four times.
This page covers what each seat actually does, who pays for it, when you need a full exit advisor and when you do not, and the questions worth asking before you sign anything.
What do business exit advisors do?
A business exit advisor, sometimes called an M&A advisor or a sell-side advisor, manages the sale of your company on your behalf. The work breaks into four phases.
Preparation. Cleaning up the financials so a buyer's diligence team does not find surprises. Normalizing owner compensation and one-time expenses so the earnings figure a buyer underwrites is defensible. Documenting customer concentration, supplier terms, and anything else a buyer will ask about anyway.
Positioning. Writing the materials a buyer reads first, usually a teaser and a confidential information memorandum, and deciding what the business is actually being sold as. A distribution business with a software layer can be marketed as either, and the two attract different buyers at different multiples.
Process. Building and contacting the buyer list, running the bid timeline, and keeping more than one party interested for as long as possible. This is the part owners most often underestimate. A single interested buyer is a negotiation with no leverage.
Close. Managing diligence requests, coordinating with the attorney on the purchase agreement, and keeping the deal moving when it stalls, which it usually does at least once.
The five advisors in a typical business sale, and who pays each one
| Seat | What they do | Typical fee shape | Who pays |
|---|---|---|---|
| Exit or M&A advisor | Runs the sale process end to end | Retainer plus a success fee, commonly a percentage of transaction value that steps up at higher prices | Seller |
| Transaction attorney | Drafts and negotiates the purchase agreement, disclosure schedules, escrow terms | Hourly, occasionally capped | Seller pays their own; buyer pays theirs |
| CPA or tax advisor | Models the after-tax outcome of asset versus stock structures, plans around the sale year | Hourly or fixed project fee | Seller |
| Valuation specialist | Independent opinion of value, sometimes required for estate, ESOP or partner-buyout purposes | Fixed fee | Seller |
| Capital advisor | Arranges financing on either side of the deal, including facilities the business needs to reach the sale in good shape | Varies by structure | Varies |
The fee that surprises owners is the success fee. It is normal for it to be the largest single cost of the transaction, and it is also the one most directly tied to outcome, so it is the wrong place to shop purely on price.
When do you need a business exit advisor, and when do you not?
You probably need one when the business has more than one plausible buyer type, when enterprise value is large enough that a one or two turn difference in multiple dwarfs the fee, when you have never sold a company before, or when you need to keep running the business while the sale happens. That last one is the quiet reason most owners hire. A sale process is close to a full-time job for four to nine months.
You probably do not need a full advisor when you are selling to a known party at a price you have already agreed, when you are transferring to a family member or a long-time employee, or when the business is small enough that the fee structure does not leave room for one. In those cases a transaction attorney and a tax advisor are usually the right team, and the money saved on process is real.
The honest middle case: if you have one unsolicited offer and no idea whether it is good, start with an independent read on value before you respond. A full process may or may not follow.
How do you choose a business exit advisor?
Four things separate advisors who will do well by you from advisors who will take the retainer.
Deals actually closed in your size band and your industry. Count only deals closed in the last three years at roughly your enterprise value. An advisor who closes $50M deals is usually a weaker fit for a $6M business, because the process they run is built for a different buyer universe.
Who does the work. Ask which named person will be on your calls every week. In smaller firms the partner who pitches is the partner who works. In larger ones the work often moves to a junior team, which is normal and worth knowing before you sign.
Their buyer list, and where it comes from. A real advisor will describe how they build the list for a business like yours: strategic acquirers in adjacent categories, private equity platforms with a relevant thesis, family offices, and sometimes a competitor you would not have approached yourself. Vagueness here is the single most useful warning sign.
References you choose. Ask for three sellers from the last two years and pick which ones you call.
How does exit financing change which advisor you need?
Financing shows up in a sale in two directions, and they call for different help.
On the buy side, your buyer almost always borrows to fund the purchase. Their financing is your closing risk. A deal that depends on an SBA acquisition loan, a bank facility, or a seller note behaves differently in diligence than an all-cash strategic purchase, and the timeline stretches. Your advisor should be able to tell you, early, how each bidder intends to pay and how firm that funding is.
On the sell side, the business sometimes needs capital to reach the sale in the shape a buyer wants to see. Working capital to clear a lumpy season so the trailing twelve months look like the business actually performs. A facility to settle a partner before the sale rather than during it. Equipment or inventory funded so the asset base is not visibly starved during diligence. This is where a capital advisor sits, and it is a different seat from the person running the sale process. Custom Capital Advisors is a brokerage rather than a lender, and we do not run sale processes. We work on the financing side, including the capital a business needs on the way to an exit. Our business exit financing page covers that work, and capital consulting covers the advisory side of it.
If you are earlier than that and still mapping who lends against what, types of business lenders is the plainest starting point, and asset-based lending covers the structure most often used when the balance sheet is the strength.
What does a small business exit team cost?
Ranges vary widely by market and deal size, so treat these as shapes rather than quotes, and get your own numbers in writing.
The exit advisor is a retainer plus a success fee, and the success fee is usually the largest line. The attorney is hourly and scales with how contested the purchase agreement gets. The CPA is a project fee for structure modeling plus the extra work in the sale year. A valuation, if you need a formal one, is a fixed fee.
The useful way to think about it: for a business where process genuinely moves the price, the advisor fee is paid for by the competitive tension the process creates. For a business where the buyer is already chosen and the price already agreed, a leaner team is usually the right call. Nobody can tell you which case you are in without looking at the business, and anyone who tells you otherwise before seeing numbers is selling.
What should you ask before signing an engagement letter?
- How long is the exclusivity period, and what happens if I want out?
- Does the success fee apply to a buyer I introduced myself?
- Is there a tail period after termination, and how long?
- What is the minimum fee if the deal closes below expectations?
- Who specifically is on my weekly call?
- What does your buyer list for a business like mine look like?
- What is the most common reason your deals fall apart, and at what stage?
Question 2 catches the most money. If a buyer you already know ends up buying the business, many engagement letters still trigger a full success fee, and that term is negotiable before you sign.
Common Questions
What is the difference between a business broker and an exit advisor?
Broadly, brokers handle smaller main-street businesses with a standardized process and a listing-style approach, while M&A or exit advisors run a bespoke, competitive process for larger companies. The line is blurry and the titles are not regulated, so judge on closed deals in your size band rather than on the word on the card.
How long does selling a business usually take?
Four to nine months from engagement to close is a common range, with preparation sometimes adding months before that. Deals involving buyer financing typically sit at the longer end.
Do I need a valuation before I hire an advisor?
Usually not a formal one. A good advisor will give you an indicative range early. A formal valuation is for situations that require an independent opinion, such as estate planning, an ESOP, or a partner buyout.
Can I sell without an advisor?
Yes, and owners do, most often when the buyer is already known. You still want a transaction attorney and a tax advisor. What you give up is the competitive tension that a process creates, which is where the advisor fee tends to pay for itself when there is more than one plausible buyer.
Does Custom Capital Advisors run business sales?
No. We are a brokerage, not a lender, and we work on the financing side of a transaction rather than running the sale process. We help on the capital a business needs on the way to an exit, and on buyer-side financing structure.
What happens to my business debt when I sell?
It depends on structure. In an asset sale most debt is typically paid off at close from proceeds; in a stock sale liabilities often travel with the entity unless the agreement says otherwise. This is exactly the question to put to your CPA and attorney early, because it changes your net proceeds materially.
