How Buy-Side M&A Advisors Get Paid in 2026: Buy-Side vs Sell-Side M&A Advisory Fees, Retainers, Success Fees, and Who Pays
Buy-side and sell-side M&A advisory fees use the same parts, but how buy-side M&A advisors get paid in 2026 varies more than most first-time acquirers expect: some engagements are pure success fee with no retainer, some are retainer-only for ongoing deal-sourcing relationships, and most land somewhere in between (a modest retainer creditable against a success fee at close). Which structure fits depends on your deal velocity, not the advisor’s preference.
Quick Answer
Buy Side M&A Advisory is the topic of this guide, covering what it means, how it is calculated, and the 2026 benchmarks you can use to apply it to your own business. Some buy-side engagements are pure success fee (no retainer); some are retainer-only (for ongoing deal-sourcing relationships); most lower-middle-market engagements combine a retainer with a success fee. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. A practical walkthrough of buying a franchise covers the same ground with worked examples.

What this guide covers
- Buy-side advisors are paid by the buyer who engages them, through some mix of retainer, success fee at closing, and sometimes hourly/project fees
- Retainer: monthly or upfront, often $5,000-$25,000+/month for larger engagements (or a flat upfront fee for smaller ones), sometimes credited against the success fee
- Success fee: commonly a percentage of transaction value on a Lehman/modified-Lehman scale (decreasing as deal size grows), or a fixed fee for smaller deals, paid at closing
- Structures vary: pure success fee (no retainer), retainer-only (ongoing sourcing relationships), or retainer + success fee (most common in the lower middle market)
- Separately, the buyer-paid sell-side model: an advisor represents the seller, but the buyer pays the fee at closing, so the seller pays nothing
- CT works both ways: buy side (sourcing for buyers) and sell side under the buyer-paid model (sellers pay nothing; buyer pays at closing)
The fee components of a buy-side engagement
Buy-side advisory fees are usually structured as a retainer or work fee paid during the search, plus a success fee the acquirer pays at closing, with hourly or project fees for narrowly scoped work. Some buy-side firms skip the success fee entirely: the 2024-25 North American M&A Fee Guide found that 20% of firms that mainly serve buyers charge none.
| Component | What it is | Typical range |
|---|---|---|
| Retainer (monthly or upfront) | A fee paid by the buyer during the engagement, compensating the advisor for the work of building target lists, running outreach, and qualifying opportunities, whether or not a deal closes | $5,000-$25,000+ per month for larger engagements; a flat upfront fee (often $10,000-$50,000) for smaller or shorter engagements; sometimes credited against the eventual success fee |
| Success fee (at closing) | The main compensation, paid by the buyer when a deal closes, usually a percentage of the transaction value | Commonly a Lehman or modified-Lehman scale (decreasing percentage as deal size grows, e.g., higher % on the first few million, lower above), or a fixed fee for smaller deals; minimum fees are common |
| Hourly / project fee | For specific scoped work, e.g., target identification only, or diligence support, or modeling, without a full advisory engagement | Hourly rates vary; project fees are scoped to the work |
| Expenses | Out-of-pocket costs (travel, data, third-party reports) | Usually billed separately on top of the fees; confirm |
The common buy-side engagement structures
- Pure success fee (no retainer): the advisor is paid only if a deal closes. Lower commitment for the buyer, but advisors offering this structure may prioritize buyers more likely to transact, and the success fee is often higher to compensate for the risk. More common for transactional, deal-specific engagements.
- Retainer-only: the buyer pays an ongoing retainer for a continuous deal-sourcing relationship, the advisor maintains a pipeline of opportunities matching the buyer’s criteria. Common for active acquirers (PE platforms, holdcos, serial buyers) who want a steady flow of targets and aren’t transacting on a single-deal basis.
- Retainer + success fee: the most common structure in the lower middle market. A monthly retainer (often credited against the success fee) compensates the advisor for the ongoing work, and a success fee at closing aligns the advisor with getting a deal done. Balances the advisor’s need to be paid for effort with the buyer’s desire to pay mostly for results.
- Project / hourly: for specific scoped work without a full engagement, e.g., ‘identify and screen 30 targets in this sector’ or ‘support diligence on this deal.’
Who pays in different arrangements
- Buy-side advisory: the buyer pays. The buyer engages the advisor to source, screen, and help acquire targets; the buyer pays the retainer and/or success fee. This is the standard.
- Traditional sell-side brokerage: the seller pays. The seller engages a broker to list and sell the business; the seller pays a commission (commonly 8-15% for smaller businesses) at closing. See who pays the business broker fee.
- Buyer-paid sell-side advisory: the buyer pays, even though the advisor represents the seller. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. This works because in the lower middle market, the typical buyer pool (strategic acquirers, PE-backed platforms, family offices) routinely pays sell-side advisor fees as a normal transaction cost. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. See the business broker alternative.
What you’re paying a buy-side advisor for
- Proprietary sourcing, identifying and approaching owners in your target sector, often before they’re actively for sale. This is the highest-value activity, the best deals come from proprietary outreach, not public marketplaces, and it’s labor-intensive. See how to source acquisition deals.
- Screening and qualification, filtering the funnel so you only spend diligence dollars on real opportunities. Expect to review 50-100 opportunities for every acquisition that closes; the advisor handles the top of that funnel.
- Process management, running the outreach, managing the data room, coordinating diligence, keeping the deal moving.
- Negotiation support, helping structure the offer, the LOI, and the definitive agreement terms (alongside your transactional attorney).
- Market knowledge, what businesses in your sector are worth, what structures are normal, which sellers are credible, what the competitive landscape looks like.
- For institutional buyers and serious individual acquirers, the difference between competing in auctions at full price and finding proprietary deals with room to negotiate.
How to keep a buy-side success fee from rewarding a higher price
Sell-side M&A advisory fees are built to rise with the sale price. The 2024-25 North American M&A Fee Guide, the annual survey of middle-market advisors that Firmex started in 2016, pegs the typical success fee at 5.5% for a $5 million sale, falling to 2.0% for a $150 million sale, usually on a Lehman-style declining scale. That design works for a seller, because the owner and the advisor both want the highest number.
Copy the same percentage onto a buy-side mandate and the incentive flips. An advisor paid a percentage of the purchase price earns more when you pay more. The effect rarely shows up as open price pressure. It shows up in quieter ways: less pushback on a seller’s add-backs, a softer position on the working capital peg, or a quick yes to an auction price.
Buyers who spot this usually change the success-fee design, not the advisor. The common fixes:
- Flat dollar success fee. Agree the fee in dollars when you sign the engagement, so it does not move with price.
- Fee on a fixed reference value. Apply the percentage to the price in the signed LOI or to a pre-agreed target value, whichever is lower, not to the final purchase price.
- Cap. Keep a percentage fee but set a dollar ceiling, so price increases above that level earn the advisor nothing extra.
- Price-discipline bonus. The mirror image of the sell-side accelerator, a fee that rises when a sale beats a target price and that 15% of advisors used per the Firmex US M&A Fee Guide 2023-24. On the buy side, the bonus is paid for closing below a target price instead.
- Work fees only. Pay for the search, screening and diligence support with no success fee at all, the model some buy-side firms already use.
Each fix has a cost. A flat fee or a cap can cool the advisor’s interest in a larger deal you actually want. A work-fee-only mandate costs money even if nothing closes. Match the design to how often you buy: a serial acquirer can carry ongoing work fees, while a one-time buyer usually prefers a capped success fee. Buyers are pressing on these terms more often, too: in the same 2024-25 survey, 30% of firms that mainly serve buyers reported more client pressure to cut fees, up from 11% a year earlier. For retainer ranges and Lehman math at specific deal sizes, see our M&A advisor fees guide.
Buy-side vs sell-side M&A advisory fees: how the two compare
Buy-side and sell-side M&A advisory fees share the same building blocks, a retainer plus a success fee, but they are paid by opposite parties and reward opposite outcomes. Buy-side advisory fees are paid by the acquirer and reward a disciplined purchase price; sell-side advisory fees are paid by the seller and reward a higher sale price.
Sell-side M&A advisory fees follow the structure most owners already know. The seller engages an advisor or broker, pays a monthly retainer during the process, and pays a success fee at close that rises with the sale price. Because the advisor earns more when the business sells for more, the seller and the advisor are aligned on maximizing proceeds. This is the fee model behind the phrase “sell side advisory fees,” and it has been the default for owner exits for decades.
Buy-side M&A advisory fees invert that alignment. The acquirer pays the retainer and the success fee, so the advisor works to source the right target, run diligence, and hold the line on price. A success fee that scales with transaction value creates an obvious tension on the buy side, which is why the fee components of a buy-side engagement matter so much: a well-structured buy-side agreement rewards the advisor for closing a good deal, not simply a big one.
No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. For a seller weighing “buy side vs sell side advisory fees,” this removes the fee question entirely from their side of the table. CT Acquisitions runs this model, and you can see how it changes the economics on our business broker alternative page.
How CT Acquisitions works
CT works on both sides of the deal:
- Buy side: we source and screen acquisition targets for capital partners and individual buyers, building target lists against the buyer’s thesis, running proprietary outreach, qualifying opportunities, and supporting the deal to close. The buyer engages and pays us.
- Sell side, under the buyer-paid model: when we represent a seller, the advisory fee is structured to be paid by the buyer at closing, not the seller. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. This works because our buyer network, 500+ active capital partners, routinely pays sell-side advisor fees as a normal transaction cost. See our broker alternative guide.
For acquirers: see how to source acquisition deals, business acquisition strategy, and how to find businesses for sale. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing.

Frequently asked questions
What are buy side M&A advisory fees?
Buy side M&A advisory fees are what an acquirer pays a buy-side advisor to find, evaluate, and close an acquisition. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. The structure is meant to reward a disciplined purchase, so the success-fee terms should be set so the advisor is not simply incentivized by a higher price.
How do buy-side M&A advisors get paid?
By the buyer who engages them, through some combination of: a retainer (a monthly or upfront fee, often $5,000-$25,000+ per month for larger engagements, or a flat upfront fee for smaller ones, sometimes credited against the success fee); a success fee paid at closing (commonly a percentage of the transaction value on a Lehman or modified-Lehman scale that decreases as deal size grows, or a fixed fee for smaller deals); and sometimes an hourly or project-fee arrangement for specific scoped work. The structure varies, pure success fee, retainer-only, or retainer plus success fee, with retainer-plus-success-fee being the most common in the lower middle market.
Does the buyer or the seller pay a buy-side advisor?
The buyer. A buy-side advisor is engaged by the buyer to source, screen, and help acquire targets, and the buyer pays the retainer and/or success fee. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing.
How much does a buy-side advisor cost?
It depends on the engagement structure and deal size. Retainers run roughly $5,000-$25,000+ per month for larger engagements, or a flat upfront fee (often $10,000-$50,000) for smaller ones, sometimes credited against the success fee. Success fees are commonly a percentage of the transaction value on a Lehman or modified-Lehman scale (a higher percentage on the first few million, lower above), or a fixed fee for smaller deals, with minimum fees common. A pure-success-fee engagement (no retainer) typically carries a higher success-fee percentage to compensate for the risk. Expenses are usually billed separately. Get the full structure, retainer, success fee, minimum, expenses, credit mechanics, in writing.
What’s the difference between a buy-side advisor and a business broker?
No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. A business broker is typically engaged by and works for the seller, listing, marketing, and selling the business, and is paid by the seller (commonly 8-15% for smaller businesses). No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. The key questions: who does the advisor represent (buyer or seller), and who pays (buyer or seller). No fee to you on buy-side introductions; sell-side mandates are paid on success at closing.
Should I hire a buy-side advisor to buy a business?
For serious acquirers, often yes, especially PE platforms, holdcos, serial buyers, and individual buyers who want proprietary deal flow rather than competing in public-marketplace auctions. A buy-side advisor’s value is mostly in the proprietary sourcing (identifying and approaching owners before they’re actively for sale, where the best deals come from) and the screening (filtering the funnel so you only spend diligence dollars on real opportunities). For a one-time buyer who already has an identified target, a buy-side advisor adds less, you mostly need a transactional attorney and a lender. The decision turns on whether you need deal flow.
No fee to you on buy-side introductions; sell-side mandates are paid on success at closing.
No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. This works because in the lower middle market, the typical buyer pool, strategic acquirers, PE-backed platforms, family offices, routinely pays sell-side advisor fees as a normal transaction cost; they prefer working with advisors because it’s faster, more confidential, and reaches better-fit deals than chasing public listings. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. See our broker alternative guide.
Do buy-side advisors charge a retainer?
Often, but not always. Retainer-plus-success-fee is the most common structure in the lower middle market, a monthly retainer (often $5,000-$25,000+ for larger engagements, often credited against the success fee) compensates the advisor for the ongoing sourcing and screening work, and a success fee at closing aligns the advisor with getting a deal done. Some engagements are pure success fee (no retainer, but typically a higher success-fee percentage to compensate for the risk), and some are retainer-only (for ongoing deal-sourcing relationships with active acquirers). The right structure depends on the buyer’s situation, a serial acquirer wanting steady deal flow vs a one-time buyer pursuing a specific deal.
How does CT Acquisitions get paid?
On the buy side, the buyer engages and pays us, to source and screen acquisition targets against their thesis, run proprietary outreach, qualify opportunities, and support the deal to close. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. This works because our buyer network of 500+ active capital partners routinely pays sell-side advisor fees as a normal transaction cost. See our broker alternative guide for the sell-side model and our deal-sourcing pages for the buy-side.
What is the typical M&A advisory fee percentage?
M&A advisory fees typically run 1-2% of transaction value on larger deals ($100M+), 2-5% on middle-market deals ($10M-$100M), and 5-10% on smaller deals ($1M-$10M), often with floor minimums. Buy-side and sell-side fees follow similar percentage curves but compensate different parties: sell-side fees are paid by the seller at close, buy-side by the buyer. Retainers of $5K-$25K per month often apply, sometimes credited against the success fee at closing.
How much does an M&A advisor charge?
An M&A advisor charges through three components: a retainer (often $5K-$25K per month, sometimes a flat upfront fee), a success fee (1-2% on deals above $100M, 2-5% middle market, 5-10% below $10M), and occasional expense reimbursements. On larger engagements, retainers often credit against success at closing. For sub-$1M deals, business brokers typically charge 8-12% success-only rather than the retainer-plus-success model used by traditional M&A advisors.
How much are sell-side M&A advisory fees?
Sell-side M&A advisory fees are paid by the seller at closing and typically run 1-2% of transaction value above $100M, 2-5% in the $10M-$100M middle market, and 5-10% below $10M, with floor minimums on smaller engagements. Retainers of $5K-$25K per month commonly apply alongside success fees. Sell-side fees are structured to align the advisor with maximum sale price, which is why most engagements use percentage-of-deal-value pricing rather than fixed fees.
What is a typical M&A advisor fee?
A typical M&A advisor fee combines a monthly retainer ($5K-$25K, sometimes credited against the success fee) with a success fee at closing. Success fees scale inversely with deal size: 1-2% above $100M, 2-5% in the $10M-$100M range, 5-10% on deals below $10M. Buyers pay buy-side advisors; sellers pay sell-side advisors. Some engagements add tiered success fees that escalate above target valuation thresholds to align the advisor with maximizing price.
Can a buy-side advisor and a sell-side advisor both be paid on the same deal?
Yes. In a standard deal each side pays its own advisor: the seller pays the sell-side advisor’s success fee out of the sale proceeds, and the buyer pays the buy-side advisor’s retainer and success fee. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. Ask each advisor to state in writing who pays and when.
Do you owe a buy-side advisor anything if you walk away from a deal?
You owe no success fee unless a deal closes, but retainer or work fees already paid are rarely refunded. Check two clauses before signing: the tail, which can make a success fee due if you later buy a target the advisor introduced, and any break-up fee. The 2024-25 North American M&A Fee Guide found that 21% of surveyed advisors, most of whom represent sellers, charge a break-up fee when a client rejects a bona fide offer.
