How do fee models differ between business brokers and M&A advisors?
Business brokers typically charge success-only fees ranging from 8–12% on transactions under $1 million in Canada, while M&A advisors typically charge a monthly retainer ranging from $5,000 to $25,000 per month plus a success fee of 2–5% on larger deals. The fundamental difference is timing: brokers get paid only when your business sells, while M&A advisors require ongoing payment during the engagement period regardless of outcome. Note that a business broker's upfront retainer (a one-time $5,000–$25,000 fee, typically deducted from the closing commission) is a different structure from the M&A advisor's monthly retainer — the same dollar range describes two distinct payment mechanisms.
Business Broker Fee Models
Business brokers focus on businesses valued under $2 million and typically serve owner-operators. Among Advisor Standard profiles with disclosed fee information, 73% use success-only fee structures.
In most cases, broker commissions follow a percentage-of-sale-price model. For transactions under $1 million, the standard rate is 8-12% of the final purchase price. On larger deals, many brokers use the Lehman Formula, which calculates success fees 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.
Business broker commissions are subject to GST/HST as a taxable professional service under the Canada Revenue Agency Excise Tax Act section 165.
The success-only model means sellers pay nothing upfront and incur no costs if the business does not sell. The tradeoff is a higher total fee percentage compared to retainer models.
M&A Advisor Fee Models
M&A advisors typically work on transactions above $2 million and serve businesses with institutional buyers or private equity interest. Among Advisor Standard profiles with disclosed fee information, 82% use retainer-plus-success fee structures.
Commonly, M&A advisors charge a monthly retainer of $5,000 to $25,000 per month for an engagement period that typically runs 6–12 months. Whether monthly retainers are credited against the final success fee varies by advisor and engagement — some credit them as advance payments against success fee, others treat them as separate compensation for engagement work. Confirm the specific treatment before signing.
Success fees for M&A advisors on deals above $2 million typically range from 2–5% of transaction value — substantially lower than broker percentages because of the retainer component.
According to the Association for Corporate Growth (ACG) Canada Fee Study 2023, retainer arrangements filter out sellers who are not serious about completing a transaction. The ongoing cost signals commitment and ensures the advisor is compensated for work even if the seller decides not to proceed.
When Each Model Makes Sense
The fee model transition point typically occurs at transaction values between $2-5 million, where retainer models become more common than success-only structures.
For smaller transactions under $2 million, success-only broker fees align incentives without requiring upfront capital from the seller. For larger deals, the retainer model reflects the increased complexity and longer timeline of institutional transactions, where the advisor's work begins months before a buyer is identified.
Total Cost Comparison
For a $5 million transaction, fee structures look materially different. Under a success-only broker model using the Lehman Formula (5%/4%/3%/2%/1% by tranche), total commission on a $5M deal calculates to approximately $150,000 ($50K + $40K + $30K + $20K + $10K). Brokers using a flat percentage on deals in this size range typically charge 4–6%, producing fees of $200,000–$300,000. The $5M threshold is near the transition point where Lehman-based structures often produce lower total fees than flat-percentage arrangements.
Under a retainer-plus-success model, fees might be $90,000–$150,000 in monthly retainers over 6–12 months plus a success fee of 2–4% ($100,000–$200,000 on $5M), suggesting total costs in the $200,000–$350,000 range — but with retainer costs frontloaded before close.
The retainer model frontloads costs but typically results in lower total percentages on larger deals. The success-only model defers all costs to closing but charges higher percentages to compensate for the advisor's risk.
