The Real Cost of Selling a Business

That is not the right time to learn it.

This article breaks the number down line by line. Where it comes from, what each piece pays for, and which pieces are negotiable. Then it shows the alternative cost structure, the one most owners did not know existed five years ago, and walks through what it actually costs to sell a business without paying a broker the price of a luxury car.

By the end you should be able to look at any sale-cost quote and know exactly what you are paying for, what you can skip, and where you would be foolish to try to save money.

The standard quote, line by line

This is what a typical broker engagement actually costs on a $1.5 million sale. The numbers come from published Double Lehman formulas, IBBA broker compensation surveys, and the standard professional services rates for small business M&A.

Where the $140,000 commission actually comes from

The commission math is not arbitrary. Most brokers handling deals between $1 million and $5 million use what is called the Double Lehman formula, a graduated rate that produces a single combined fee.

For sales under $1 million, most brokers move to a flat 10 to 12 percent of the sale price, with a minimum commission of $10,000 to $25,000. For sales above $5 million, brokers shift to a Modern Lehman structure that lands around 4 to 6 percent of the sale price.

The structure is consistent across the industry because it was designed to reward brokers for sales-side acquisition work that scales with deal complexity. A $5 million deal is structurally more involved than a $500,000 deal. A higher-tier rate on the first dollars of sale price compensates the broker for the irreducible work that happens on every transaction.

The honest question is whether the commission tracks the actual work the broker does on a typical small business sale today. We will come back to that.

What you pay for, beyond the commission

The other line items above are not optional, but they vary by who you hire and how prepared you are.

Upfront broker retainer. Most brokers charge a $2,000 to $10,000 retainer at signing. Often this is non-refundable and is credited against the eventual commission only if the deal closes. If you list and do not sell, the retainer is gone. Always ask. Some brokers waive the retainer for owner-operated businesses with strong financials.

Marketing package. A "premium listing" on BizBuySell or BizQuest costs $60 to $250 per month for an individual seller. The same listing through a broker is typically packaged into a "marketing fee" of $3,000 to $8,000, which covers the listing plus broker time to produce the teaser, screen inquiries, and run outreach to their internal buyer database.

Business appraisal. A formal third-party valuation runs $2,000 to $25,000 depending on complexity. SBA lenders order their own independent appraisal during underwriting (paid by the buyer, typically $2,500 to $7,500), so the seller-side appraisal is mostly used for setting the asking price defensibly. Sellers who have already produced a defensible valuation on their own can usually skip the formal appraisal.

CPA recasting. Getting three years of financials into accrual-basis, lender-ready format typically takes a CPA 20 to 40 hours. Rates run $150 to $300 per hour for a competent small business CPA, putting the total in the $3,000 to $8,000 range. This is one of the highest-return spend items in the entire process and almost never worth cutting. See what is SDE and why it determines your sale price for what this work actually produces.

Seller-side attorney. Plan for $5,000 to $15,000 over the life of the deal. The work is concentrated in three phases: a $1,500 to $4,000 spend at LOI signing, a $3,000 to $8,000 spend during definitive agreement drafting, and a $1,000 to $3,000 spend at closing. Complex deals (multi-entity structures, real estate carve-outs, earnouts with performance contingencies) push the high end of every range.

Escrow and closing costs. Title and escrow services for a business sale typically run $2,000 to $5,000. The buyer's lender adds their own loan-origination fees, but those are paid by the buyer. If real estate is included in the sale, add another $1,000 to $3,000 for the real estate piece of closing.

The alternative cost structure

The traditional cost structure exists because, for decades, the seller had no other option. The technology to produce a CIM, run a defensible valuation, qualify buyers, organize a data room, and close a deal did not exist as a self-service product. Brokers were the only path. The 10 percent commission was priced for that monopoly.

That market structure no longer holds. Software platforms now handle the structured parts of the work at a fraction of the cost. Sellers who use them, along with an attorney for legal review, pay a different number for the same outcome.

The savings on a $1.5 million deal is roughly $150,000. On a $1 million deal it is around $100,000. On a $3 million deal it is around $250,000. Every dollar saved goes directly to the seller's net proceeds, before taxes.

What the platform actually does

The reasonable question is what BizTender does instead of the broker, and whether the substitution is complete. The honest answer is that the platform handles the structured work, while the seller handles the judgment work. Here is the split.

The substitution is not 100 percent, and the honest version of the pitch is that it is not supposed to be. A competent broker brings 15 to 30 years of judgment from running deals. A platform brings the structure that lets your judgment scale. For owners who have run a business for a decade and want the operational control they are used to having, the platform plus their own judgment plus an attorney is the right combination. For owners who genuinely want a fiduciary to run the process for them, a broker remains the right answer. The question is whether the commission tracks the actual value you receive.

Where you should never cut costs

There are two line items in every sale where trying to save money costs you more than it saves. Skip these and your deal will either fail or close at a worse price than it should have.

A real M&A attorney. A general-practice attorney can probably write a will, draft a divorce settlement, and represent you in small claims court. They cannot competently negotiate the LOI, draft the definitive agreements, and protect your interests in indemnification disputes for a business sale. Find an attorney who works on small business M&A regularly. Pay $5,000 to $15,000 for the engagement. The first time you encounter a working capital adjustment, a representation-and-warranty challenge, or a non-compete enforcement question, the money is already saved. We have seen sellers try to save $5,000 by using their general attorney and lose $50,000 to $200,000 in negotiation value or post-close indemnification claims.

Clean financials and a defensible valuation. Whatever you save by skipping CPA recasting or by setting your own price without market data, you lose ten times over in due diligence. The buyer's lender will recalculate your SDE. The buyer's accountant will challenge your add-backs. If your numbers do not hold up, the deal either dies or the price drops. Sellers who do the financial preparation work upfront close at their asking price. Sellers who skip it close at 70 to 80 percent of their asking price, if they close at all. See what is SDE and why it determines your sale price for the underlying math.

The pattern: spend money on judgment-driven work (attorney, CPA), save money on structured work (CIM production, buyer matching, deal room logistics). The platform replaces the structured work. The professionals stay.

What it costs to wait

There is one cost most sellers do not count: the time-and-effort cost of not selling efficiently. A business that sits on market for 18 months without selling has real opportunity costs.

• The seller's own time: 5 to 15 hours per week of buyer communication for 18 months is 500 to 1,400 hours of focused work, on top of running the business.
• Listing fees during that period: $1,000 to $5,000 in direct platform costs.
• Deal cycle costs: each failed deal involves $5,000 to $15,000 of attorney time on LOIs and partial diligence work that never gets recovered.
• Owner burnout: harder to quantify but real. Owners who go through 18 months of failed deals often lower their asking price out of exhaustion rather than market signal.

A prepared sale that closes in 7 to 9 months avoids most of these costs. The fastest path to a prepared sale is the platform-assisted workflow plus a strong attorney. See how long does it take to sell a small business for the full timeline breakdown.

The full comparison, on three deal sizes

The arithmetic depends on the size of the sale. Here is how it lands across the most common deal sizes for owner-operated businesses.

Note that the brokered total does not scale linearly. The Double Lehman formula bakes in graduated rates, so larger deals get proportionally smaller commission percentages but larger absolute commission dollars. The self-directed path scales mostly on attorney fees, which grow modestly with deal complexity rather than with deal size.

On every deal size in the table, the savings exceeds 50 percent of the all-in cost. On the typical $1.5 million sale, the savings is 88 percent.

What about flat-fee brokers?

There is a middle category worth understanding. Flat-fee brokers charge $5,000 to $25,000 for a defined service package (CIM production, listing setup, some buyer communication). They are a real alternative to commission-based brokers for sellers who want a human professional involved but do not want to pay 10 percent of their sale price.

The trade-off: flat-fee brokers have less incentive to push for a high sale price because their compensation is fixed at the start. Most do not provide the depth of negotiation support that commission-based brokers do. They are typically a smaller operation and may not have an internal buyer network of any size.

A platform like BizTender provides the structured work (CIM, valuation, buyer matching, deal room) at lower cost than a flat-fee broker and adds the buyer-matching layer that flat-fee brokers usually cannot match. The flat-fee broker can be a good middle option for sellers who specifically want a human professional involved in their day-to-day. The platform is the right answer for sellers who want maximum control and minimum cost.
