Transparent M&A advisor fees should answer six questions before you sign: what percentage is charged, what value base is used, whether there is a fee cap, whether any retainer is payable, whether expenses are recharged, and whether the fee is due only at closing. Lyndon Advisory publishes a simple model: 2% of enterprise value, capped at US$300,000, with no retainer, monthly fee, or expense recharge.
The practical goal is not to find the lowest headline percentage. It is to avoid surprise economics that reduce seller proceeds after a buyer has already been found.
The Fee Transparency Checklist
| Fee point | What to demand in writing | Lyndon Advisory model |
|---|---|---|
| Success fee | Exact percentage and whether it applies to enterprise value or equity value | 2% of enterprise value |
| Fee cap | Maximum dollar fee at larger deal sizes | US$300,000 cap |
| Retainer | Amount, duration, and whether it credits against the success fee | None |
| Expenses | Data room, travel, research, printing, admin, and markups | No expense recharge |
| Tail provision | Named buyer list, substantive contact standard, and duration | Narrow, buyer-specific terms only if mandated |
| Payment trigger | Whether fee is due at LOI, signing, or closing | Only if the transaction closes |
Axial’s 2026 M&A Fee Guide tracks engagement fees, success fees, capital raising mandates, expense policies, and advisor pricing practices across the lower middle market. That range of structures is exactly why owners should compare the full engagement letter, not only the percentage in a proposal.
Why Opaque Fees Hurt Sellers
Opaque fees create three problems.
They make proposals hard to compare. A 3% success fee with a US$15,000 monthly retainer, expense reimbursement, and 24-month tail may cost more than a higher-looking success fee with no pre-closing economics.
They weaken alignment. A meaningful retainer can be reasonable when it buys real preparation work. But if too much of the advisor’s economics is earned before buyer progress, the seller carries more execution risk.
They reduce net proceeds late in the process. Sellers often discover the real cost only after a letter of intent, due diligence, or final negotiation has started. At that point, switching advisors is difficult.
“Fee transparency is not cosmetic. It changes the owner’s decision quality. A seller should know before signing whether the advisor is paid for closing, paid for time, paid for expenses, or paid through a broad tail after termination.”
— Daniel Bae, Founder & CEO, Lyndon Advisory
What Transparent Fees Should Include
| Engagement-letter term | Transparent version | Seller risk if vague |
|---|---|---|
| Fee basis | Defines enterprise value, debt, cash, working capital, and assumed liabilities | Seller may pay on value not received as equity proceeds |
| Minimum fee | Dollar minimum shown at likely valuation levels | Percentage understates actual cost |
| Retainer credit | 100% credited against success fee if a retainer exists | Seller pays twice for the same work |
| Expense policy | Written cap or no recharge | Admin and travel costs grow without control |
| Tail buyer list | Only buyers with substantive contact | Fee can apply to weak or stale names |
| Closing trigger | Payable only on transaction completion | Seller pays despite failed closing |
The IBBA and M&A Source publish Market Pulse research on Main Street and lower-middle-market transactions. Their Q2 2026 highlights reinforce a basic point: sellers operate across a fragmented marketplace, so clean engagement terms matter.
How Lyndon Makes Fees Clear
Lyndon Advisory uses one public fee schedule.
| Question | Answer |
|---|---|
| What is the fee? | 2% of enterprise value |
| Is there a cap? | Yes, US$300,000 |
| Is there a retainer? | No |
| Are monthly fees charged? | No |
| Are expenses recharged? | No |
| Is the fee due if no deal closes? | No |
| Does submitting the valuation form create a mandate? | No |
That structure is deliberately boring. It lets a seller model net proceeds before starting a process, compare proposals from advisors or brokers, and decide whether a full sell-side process is worth pursuing.
Transparency Does Not Replace Process Quality
Fee transparency is only one screen. A transparent but passive advisor is still a weak choice. Owners should also test whether the advisor will prepare:
- a defensible valuation range;
- a buyer map covering strategic buyers, private equity, family offices, and cross-border acquirers;
- a teaser, CIM, and financial model;
- a staged confidentiality process with NDA before identity disclosure;
- tracked, targeted outreach rather than a public listing; and
- negotiation and diligence support through closing.
The SBA business valuation guide emphasizes financial condition, assets, and comparable market evidence when estimating business value. Advisory fees should be judged against the same discipline: what work is being performed, what outcome is being pursued, and what the seller pays if that outcome does not happen.
