Who Pays the Business Broker Fee: Buyer or Seller, and What It Costs You

Short answer: the seller pays the business broker fee. The broker is retained by the seller, the commission is a percentage of the sale price, and it is deducted from the seller's proceeds at closing, normally through escrow. The buyer never writes the broker a check in a standard deal, but the buyer does pay for it indirectly, because the commission is baked into the asking price. The exception is buy-side representation, where a buyer hires and pays their own advisor.

That is the whole answer for 95% of small-business and online-business deals. The remaining 5% is where the money actually gets interesting: co-brokered deals, buy-side retainers, dual agency, and the moment in an SBA-financed acquisition when who paid whom starts to matter to a lender. This walks through all of it, with the fee schedules we could verify firsthand in August 2026.

Who pays the business broker fee, buyer or seller?

The seller. In a standard sell-side engagement, the business owner signs a listing agreement with the broker that sets a commission, an exclusivity period and a tail clause. When the business sells, the escrow or closing agent deducts the commission from the sale proceeds and pays the broker directly, then wires the rest to the seller. The buyer's funds pass through, but the buyer is not a party to the fee agreement and has no obligation under it.

This is not a courtesy. It follows from who the broker works for. A sell-side broker owes their duties to the seller: getting the highest price, screening buyers, and running a process that closes. If the buyer were paying, those duties would conflict. When you are a buyer talking to a listing broker, keep that in mind. They are pleasant, they are helpful, and they are not on your side of the table.

Does the buyer really pay for it anyway?

Yes, in the same sense that a homebuyer pays the realtor's commission. The seller sets an asking price they can live with after fees. If a broker takes 15%, the seller needs a number 15% higher than their walk-away figure. That gets built into the price you are quoted, whether or not anybody says so out loud. Buyers who want that money back on the table often go looking for businesses for sale by owner instead, which trades the commission for doing the broker's verification work yourself.

Which means the commission structure is genuinely your business as a buyer, not just the seller's. Here is what the published rates looked like in August 2026, read from each provider's own pages:

Note the second column. Several marketplaces charge both sides: the seller pays a commission on close and the buyer pays for access to full financials and seller contact. That is not a broker fee, it is a subscription, and it is not deducted from the deal. We keep a fully sourced breakdown of every one of these on our business broker fees page, including what the same sale price costs at each venue.

What is buy-side representation and what does it cost?

Buy-side representation is when you, the buyer, retain your own advisor to find, evaluate and negotiate acquisitions on your behalf. You pay them. It is common among search funds, family offices and serial acquirers, and rare among first-time buyers of small online businesses.

Structures vary and almost nobody publishes rates, but the common shapes are a monthly retainer plus a success fee on a completed acquisition, a flat project fee for a defined search, or a success fee alone at a percentage of purchase price. The success fee is often quoted on a Lehman-style scale, the same convention used on the sell side. Where a buy-side advisor genuinely earns their money is off-market sourcing: finding owners who were never going to list, which is the only reliable way to avoid competing with a dozen other bidders on a public listing.

One thing to establish in writing before you engage anyone: whether they will accept a co-broke or referral fee from the sell-side broker on deals they bring you. If they will, they are being paid by both sides, and their advice is worth less than you think you are paying for.

What is co-brokering and does it cost the buyer more?

Co-brokering is when two brokers split a single commission: one represents the seller and has the listing, the other brought the buyer. The total fee the seller pays does not change. It gets divided, commonly 50-50, occasionally on other splits set by the listing broker's co-broke policy.

For a buyer, co-brokering costs nothing extra and is often useful, because it means someone in the room has an incentive to get your side to closing. The catch is that a co-broking agent paid out of the seller's commission is still, technically, being compensated by the seller. Read that as a bias, not as fraud. Several of the larger online-business brokers publish a co-brokering page describing how they work with outside agents, which is a reasonable signal that they will engage with a buyer's representative at all.

Can the buyer pay the broker fee instead?

Occasionally, and it is usually a negotiating device rather than a genuine transfer. A seller who wants a clean headline number sometimes proposes that the buyer cover the commission on top of an agreed price. Economically that is identical to raising the price by the commission amount, so treat it as a price change and re-run your model, not as a favor.

There is one situation where it stops being cosmetic: SBA-financed acquisitions. Under SOP 50 10 8, effective 1 June 2025, an SBA business acquisition requires a minimum 10% equity injection from the buyer, a seller note only counts toward that injection if it is on full standby for the entire loan term and cannot exceed half the required injection, and a partial change of ownership requires personal guarantees from every equity holder for at least two years. Anything that shifts costs between the parties can move the numbers a lender is underwriting. If SBA financing is part of your structure, get the fee allocation in front of the lender before you agree to it, not after.

Do you pay the broker fee if the deal falls apart?

Not the success fee, in almost every arrangement. Success fees are contingent on a completed closing. That is the entire reason they are as high as they are.

Two things do survive a dead deal. First, retainers: on larger engagements a monthly retainer is paid regardless of outcome, usually credited against the success fee if a sale happens. Second, the tail clause. A tail keeps the broker owed a commission if the seller closes with a buyer the broker introduced, for a defined period after the listing agreement ends. Twelve to twenty-four months is typical. If you are a buyer who walked away from a listing and later approach the same seller directly, expect the tail to follow you. Sellers should ask for the tail to apply only to a named written list of introduced buyers, not to any sale to anyone.

How do you check what the fee is buying?

Whoever pays it, the commission is only justified by work someone actually did. As a buyer, the useful test is what the broker verified before publishing the listing, because that determines how much of the diligence bill lands on you.

Ask three questions. Did anyone reconcile stated revenue to a bank account, or is this a screenshot of a dashboard? Was the profit figure adjusted, and if so, which add-backs were accepted? Were the customer numbers pulled from the billing system or typed into a form? A broker charging 15% who did all three has earned a lot of it. A broker charging 15% who published what the seller sent them has not, and you are about to do that work yourself.

The mechanical part of that work is more tedious than hard. You want at least twenty-four months of billing exports lined up against the bank account the money settles into. If the seller can only give you PDF statements, turn them into a spreadsheet you can total before you start matching anything, because eyeballing a year of deposits against a revenue claim is how people miss refunds and chargebacks. Discrepancies usually appear in three places: refunds netted out of reported revenue, annual plans recognized as a lump in the month they were charged, and failed payments still counted as active subscriptions.

Is the broker fee negotiable, and by whom?

By the seller, before signing, and the headline percentage is rarely the part that moves. What moves is the minimum fee in dollars, the exclusivity term, the length and scope of the tail, whether a retainer is credited against the success fee, and the definition of the amount the percentage applies to. That last one matters more than people expect. A fee on "total consideration" can include earnouts you have not received yet and debt the buyer assumed. A fee on cash at close cannot.

As a buyer, you cannot negotiate the seller's commission, but you can negotiate around it. If you know the seller is paying a $10,000 minimum on a small deal, you know their true walk-away number is $10,000 above what they say it is, and you know that a deal falling through costs them nothing in commission but costs them months. Both of those are useful facts in a price conversation. Our sourced breakdown of business broker fees lists which venues publish a minimum and which do not, and the Lehman formula guide works through the tiered scales with numbers.

What this means if you are buying

Assume the commission is in the price. On a small online business bought through a curated broker, somewhere between 10% and 15% of what you are paying is the seller's cost of running a brokered process. That is not a reason to avoid brokered deals, because a broker who genuinely vetted the books has saved you real time and real risk. It is a reason to find out which of those you are actually buying.

Then look at where the listing came from. A business listed on a self-serve marketplace at an 8% seller fee has less commission baked in than the same business listed at 15%, which shows up either in the asking price or in the seller's willingness to move. When you are comparing two similar listings on different venues, the fee structure behind each one is part of the comparison. It is one of the few pieces of a deal you can research before you ever contact the seller, and on SaaS companies for sale specifically, the gap between venues is wide enough to matter.

The short version

1. The seller pays the business broker fee, out of proceeds at closing, through escrow.
2. The buyer pays it indirectly, because the seller prices it in.
3. Buy-side representation is the exception: there the buyer retains and pays their own advisor.
4. Co-brokering splits one commission between two brokers and costs the buyer nothing extra.
5. Success fees are contingent on closing; retainers and tail clauses are not.
6. If SBA financing is involved, get any fee reallocation in front of the lender first.
7. The fee is only worth what the broker verified, so ask what they checked before you trust the listing.
