Ask five brokers what they charge to sell a $1.5 million janitorial company and you'll get five different answers wrapped in similar-sounding language. The number that actually lands on the closing statement depends on which fee structure the broker uses, not just the headline percentage they quote in the first meeting. A flat 10% and a Double Lehman scale sound close but diverge fast once the sale price climbs past the first million.
The three fee structures brokers actually use
Nearly every business broker working sub-$5 million cleaning company sales prices the engagement one of three ways. Flat-percentage pricing charges a single rate, commonly 8% to 12%, against the entire sale price, and dominates deals under $1 million where the dollar amounts are small enough that a flat rate doesn't produce an outsized fee, per 1-800-BizBroker's 2026 commission survey. The Lehman formula, developed decades ago by the original Lehman Brothers, charges 5% on the first $1 million, 4% on the second, 3% on the third, 2% on the fourth, and 1% above that. It's rarely used today because the fees it generates on smaller deals don't cover a broker's marketing and diligence costs. The Double Lehman formula doubles each Lehman tier: 10% on the first $1 million, 8% on the second, 6% on the third, 4% on the fourth, and 2% above $4 million, and it has become the de facto standard for lower middle market service business sales according to Morgan & Westfield's business broker fee guide.
A cleaning company selling for $2.5 million under Double Lehman generates a commission of $100,000 (first $1M at 10%) plus $80,000 (second $1M at 8%) plus $30,000 (final $500K at 6%), for $210,000 total, an effective rate of 8.4%. The same deal under a flat 10% fee would cost $250,000. The gap widens as deal size grows, which is exactly why brokers push flat-rate pricing on larger transactions and sellers should push back toward a tiered structure.
Commission by deal size
| Sale price | Typical structure | Effective commission | Minimum fee floor |
|---|---|---|---|
| Under $500,000 | Flat rate | 10%–12% | $10,000–$15,000 |
| $500,000–$1,000,000 | Flat rate or Double Lehman | 8%–10% | $25,000 |
| $1,000,000–$3,000,000 | Double Lehman | 6.5%–9% | Rarely applies |
| $3,000,000–$10,000,000 | Double Lehman or negotiated flat | 4%–6.5% | Retainer common |
| Above $10,000,000 | Negotiated M&A advisory fee | 2.5%–4% | Retainer $25,000–$50,000 |
Retainers, tails, and the fees nobody mentions upfront
The success fee at closing isn't always the only cost. Above roughly $5 million, most intermediaries add an upfront retainer ranging from a few thousand dollars to more than $50,000, structured as a monthly or one-time engagement fee that's sometimes credited against the eventual success fee and sometimes not, according to Morgan & Westfield. Sub-$1 million deals rarely carry a retainer, but they often carry a minimum fee, meaning a $400,000 sale with a nominal 10% commission and a $25,000 floor actually costs the seller 6.25% of the stated rate once the floor kicks in on a small deal.
Read the tail provision before signing anything. A standard tail clause obligates the seller to pay the broker's commission if the business sells within 12 to 24 months of the listing agreement's expiration to any buyer the broker introduced during the engagement. That's reasonable protection against a seller cutting the broker out after doing the introduction work, but it needs a defined buyer list attached, not open-ended language that could apply to any subsequent sale.
What the commission is actually paying for
A commission that looks expensive on a spreadsheet often isn't, once you count what a broker with real cleaning-industry deal history brings: pre-qualification of buyers so an owner isn't giving financials to tire-kickers, confidential marketing that doesn't tip off employees or competitors, coordination with the buyer's SBA lender on documentation, and, the part most owners underweight, running interference during the emotionally difficult parts of negotiation so the owner-operator relationship with the buyer doesn't sour before close. On a 40-account janitorial company, a broker who has sold three or four similar businesses knows which add-backs an SBA underwriter will actually accept versus which ones will get challenged in diligence, and that judgment alone can be worth more than the commission saved by going the for-sale-by-owner route.
Negotiating the engagement before signing
The listing agreement is negotiable, and the leverage is highest before signing, not after. Three items worth pushing on: a defined minimum fee that isn't padded beyond what a small deal justifies, a sliding scale that kicks in above whatever threshold the broker proposes rather than a single blended rate, and exclusivity length. Six to nine months is standard for a cleaning company under $3 million; 12-month exclusivity with no performance benchmarks gives the broker little incentive to move quickly. A broker unwilling to negotiate any of these terms is signaling something about how the rest of the relationship will go.
| Negotiation lever | Reasonable ask | Red flag |
|---|---|---|
| Exclusivity term | 6–9 months with renewal option | 12+ months, no early-termination clause |
| Tail period | 12 months, named-buyer list attached | 24+ months, open-ended buyer definition |
| Fee structure | Double Lehman or negotiated tiered rate | Flat 10%+ on a $3M+ deal with no scale |
| Marketing spend | Itemized budget disclosed upfront | Vague "marketing included" with no detail |
On a $1.8 million janitorial sale, moving from a flat 10% fee to a properly negotiated Double Lehman structure saves roughly $28,000, enough to fund a quality-of-earnings review that could uncover a bigger problem, or benefit, before the buyer's diligence team does.
When paying full commission still beats going it alone
Owners who run the math on a $200,000 or $300,000 commission sometimes conclude they'd rather sell for-sale-by-owner and pocket the difference, and on a handful of deals that's the right call, usually when the buyer is already known, such as an employee, a competitor who's approached the seller directly, or a family member. Outside that narrow case, the commission tends to pay for itself through a higher sale price rather than costing the seller money on net. Brokers with active buyer networks routinely run a competitive process with multiple offers, and a seller negotiating one-on-one with a single interested buyer rarely has the leverage to extract a comparable price, since the buyer knows there's no other bidder pushing the number up. A broker also screens out buyers who can't actually close, which matters more in cleaning than in most industries because a large share of buyer inquiries come from first-time acquirers who haven't lined up SBA financing and won't survive underwriting once the lender sees the target's financials.
The math changes again on deals under roughly $750,000, where the fixed costs of a broker engagement (the minimum fee, the marketing spend, the time to run a formal process) start to approach the same order of magnitude as what a direct sale to a known buyer would cost in legal fees alone. A seller with one clear, motivated buyer already at the table and a business small enough that the minimum fee eats a large share of proceeds has a legitimate case for skipping the broker and hiring a transaction attorney and a CPA directly instead.
Frequently Asked Questions
Is a 10% broker fee normal for a cleaning business sale?
Yes, for deals under $1 million, where flat 8%–12% commissions are standard. Above $1 million, a properly structured Double Lehman scale typically produces a lower effective rate than a flat 10% fee, so a seller quoted a flat 10% on a $2 million-plus deal should ask why a tiered structure isn't on the table.
Can I negotiate the broker's commission on a cleaning company sale?
Yes. Exclusivity length, tail period, minimum fee floors, and the choice between flat and tiered pricing are all negotiable before signing the listing agreement. Leverage disappears once the agreement is signed.
Do brokers charge extra fees beyond the commission?
On deals above roughly $5 million, an upfront retainer is common, ranging from a few thousand dollars to $50,000 or more. Some retainers credit against the final success fee; confirm this in writing before signing.
