How does advisor compensation change between small business and mid-market deals?
Business brokers handling deals under $2 million in Canada typically charge 8–12% commission on the transaction value, while M&A advisors handling mid-market transactions ($5 million to $50 million) typically charge a monthly retainer ranging from $5,000 to $25,000 plus a success fee of 2–5% of transaction value. The transition from percentage-only to retainer-plus-success typically occurs between $2 million and $5 million in transaction value.
Small business deals: percentage-based commissions
Among Advisor Standard profiles with disclosed fee information, 73% list a percentage-based commission as their primary compensation structure for deals under $1 million. Business brokers serving the under-$2 million market typically work on a success-only basis because sellers in this segment expect to pay only if a transaction closes.
Brokers commonly apply the Lehman Formula or a variation of it. The Lehman Formula applies a declining percentage scale starting at 5% on the first $1 million, 4% on the second million, 3% on the third million, 2% on the fourth million, and 1% on amounts above $4 million. In practice, flat percentage rates in the 8–12% range are common for transactions under $2 million, with the rate negotiable based on deal complexity and expected transaction value.
Mid-market deals: retainer plus success fee structures
Among Advisor Standard profiles with disclosed fee information, 41% serving mid-market clients report using a retainer-plus-success-fee structure. Mid-market deals typically require 12–18 months of active engagement from initial valuation through closing, compared to 6–12 months for small business transactions.
Retainer fees in mid-market deals partially compensate advisors for upfront work, including detailed financial modeling, buyer sourcing, and management presentations that occur months before a deal closes. Mid-market buyers expect detailed financial documentation, quality of earnings reports, and sophisticated marketing materials that require significant advisor effort before buyer engagement begins.
The breakpoint: where compensation models typically shift
The typical transition point from percentage-only to retainer-plus-success occurs between $2 million and $5 million transaction value in the Canadian market. Below this range, sellers typically cannot afford or are unwilling to pay monthly retainers ranging from $5,000 to $25,000 before a sale closes. Above this range, the complexity and duration of the engagement make retainer structures the industry norm.
This suggests that the total cost to the seller as a percentage of transaction value tends to be higher in small business deals (8–12%) than in mid-market deals (3–7% when retainer and success fee are combined). A $1 million business sale at 10% commission costs the seller $100,000. A $10 million mid-market transaction with a $25,000 monthly retainer over 12 months plus a 3% success fee costs the seller $600,000 total — 6% of the transaction value.
Why the models differ: risk, effort, and seller sophistication
Small business brokers work on commission-only structures because their clients expect success-based pricing and cannot fund significant upfront costs. The broker's risk is higher — no payment if the deal fails — but individual deal effort is lower and timelines are shorter.
Mid-market advisors face longer timelines, more sophisticated buyers, and significantly higher upfront work requirements. Retainers shift some of that risk to the seller while ensuring the advisor is compensated for months of pre-close effort. Sellers at this level typically have the resources to fund monthly retainers and understand that quality advisory work requires upfront investment.
