How much does a business broker cost in Quebec?

Success-based fees of 5% on a $3 million sale come out to $150,000. That can look steep.

But if the broker’s competitive process brings in 15% more than what you’d have gotten on your own, that’s $450,000 in added value. The math is quick.

The three compensation models

A business broker can be paid in three ways. Each model has different implications for the seller.

The retainer

The seller pays a fixed amount — monthly or lump-sum — from the start of the engagement.

Upside: the broker is committed and paid regardless of the outcome. Downside: the seller pays even if the transaction doesn’t close.

This model is more common with advisory firms or for very complex engagements.

Success-based fees

The broker only gets paid if the transaction closes. No sale, no fees.

It’s the most common model for SME sales — and the one where interests are most directly aligned. The higher the sale price, the more the broker earns. Success fees are calculated as a percentage of the sale price.

The hybrid

A reduced retainer combined with a reduced success fee. The seller pays an upfront engagement amount, with the balance due at closing.

It’s a compromise between the first two models — and rarer among Quebec SMEs.

The contract that frames this compensation — retainer, success-based fees, or hybrid — is called the engagement letter: a document that spells out duration, exclusivity, deliverables, and exit conditions.

Typical ranges in Quebec

For Quebec SMEs, success-based fees generally fall between 3% and 10% of the sale price.

The scale is regressive: the higher the sale price, the lower the percentage.

• A business sold for $1 to $3 million: typically 6% to 10%
• A business sold for $3 to $10 million: typically 4% to 6%
• A business sold for $10 million and above: typically 3% to 5%

Most brokers also apply a minimum fee — a floor below which the engagement isn’t economically viable, regardless of the percentage.

A concrete example

Take an SME sold for $3 million with success-based fees of 5%:

$3,000,000 × 5% = $150,000

That amount is paid at closing, out of the sale proceeds. The seller doesn’t write a $150,000 cheque out of pocket — it’s a deduction from the price received.

What makes the percentage vary

• Transaction size: the higher the price, the lower the % — but the dollar amount still goes up
• Complexity: a file with multiple shareholders, real-estate assets, or transition challenges costs more to manage
• Industry: some sectors have more active buyers, which smooths the process

Calculating the ROI

Success-based fees are a cost. But that cost compares against what it brings in — not against zero.

A competitive process changes the price

When a broker takes a business to market, they create a competitive process: several qualified buyers look at the file at the same time.

Competition between buyers pushes the price up. It’s mechanical — when multiple people want the same thing, the seller has leverage.

What we see in the files is that transactions run through a competitive process generally close at a higher price — or on better terms — than what the seller would have gotten negotiating alone with a single buyer.

The size of the gain varies a lot from one file to another. The example below illustrates one possible scenario — not a market average, and not a guarantee.

The numbers in an example

Now take a $15 million sale with success-based fees at 5%:

In this example, the broker “costs” $750,000. But the seller walks away with $1,500,000 more than if they had sold on their own.

That isn’t a guarantee — it’s an observed pattern. And it’s the economic logic that explains why the vast majority of SME sellers choose to work with a broker.

Hidden fees to watch for

Success-based fees are the main cost — but they aren’t always the only one.

Here’s what to ask about before signing an engagement:

Marketing fees

Some brokers bill separately for preparing the confidential information memorandum (CIM), advertising, or going-to-market tools. Others fold everything into the success-based fees. Clarify from day one.

File fees

A lump-sum amount at the start of the engagement to cover start-up costs. It isn’t a retainer — it’s a one-time fee.

Early exit fees

If you cancel the engagement before its term, some contracts call for penalties. Read the termination clause carefully.

The tail clause

The tail clause is probably the most important clause to understand in an engagement.

It states that if a buyer identified by the broker during the engagement closes the transaction after the engagement ends — typically within 12 to 24 months — the broker still gets paid.

That’s standard and reasonable: the broker did the work of identifying and qualifying. But the duration and scope of the clause are worth negotiating.

The real cost of selling without a broker

The cost of a broker is measured in fees. The cost of not having one is measured differently.

An owner who sells on their own faces:

• A lower price: with no competitive process, the buyer negotiates from a position of strength
• A longer process: finding, qualifying, and negotiating with buyers takes time — often much more than expected
• Confidentiality risks: with no broker to filter buyers, information about the sale circulates more widely
• An emotional negotiation: selling the business you’ve built over years, facing a buyer who negotiates rationally, creates an imbalance

The real question isn’t how much it costs — it’s how much it pays back.

In most files, a good broker pays for themselves: through the margin they create on price, through the terms they protect, through the mistakes they prevent. The visible cost is the fee. The invisible cost is everything you don’t see when you sell on your own.

And what really matters isn’t just the price: it’s also the experience, the transparency, the references, the process.
