Domain Brokers Explained: What They Do and What They Cost

By the SiteAppraiser Editorial Team · Sep 4, 2026 · 5 min read

A broker sells a domain by approaching the companies that want it, rather than waiting for a buyer to arrive. What that costs, when it is worth it, and how to avoid the fake ones.

What a domain broker actually does

A marketplace is a shop window: you set a price and wait. A broker is an agent who goes looking. Given a name, a competent broker researches which companies would benefit from owning it, identifies who inside those companies can authorise the spend, approaches them directly, and negotiates on your behalf without revealing how motivated you are. The work is outbound and it is mostly human. That is the whole distinction, and it explains both the commission and the situations where a broker is worth paying.

Buy-side and sell-side are different jobs

Sell-side brokerage means you own a name and want it sold. Buy-side means you want a name someone else owns, and the broker approaches the registrant anonymously so the price is not immediately inflated by knowing a company is asking. Anonymity is the main thing you are buying on the buy side: an enquiry from a corporate email address costs real money in the counter-offer. Most firms do both, but the skills differ, and it is fair to ask which side they usually work.

What brokers charge

Expect somewhere around 15% to 20% of the sale price, success-based, on a sell-side mandate, with the percentage sometimes falling on larger deals. Buy-side is often a fixed fee or a percentage of the purchase price, occasionally with a small retainer that is credited against the commission if the deal closes. Rates move and every firm differs, so get the number in writing before you sign anything. A retainer is not automatically a red flag on the buy side, where the work happens whether or not the owner ever agrees to sell, but an upfront fee on a sell-side mandate deserves a hard question about what it buys.

When a broker beats a marketplace

Three situations. When the name is valuable enough that a percentage of a better outcome exceeds the commission, which in practice means somewhere above roughly $25,000. When the buyer pool is small and identifiable, so approaching six companies directly is more effective than being listed where none of them are looking. And when you want the sale kept quiet, because a public listing tells competitors what you are doing. Below about $10,000 the arithmetic rarely works: the commission is real and the name will find the same buyer on a marketplace.

When a marketplace is the better choice

If the name is a commodity, a marketplace is genuinely better, because value comes from distribution rather than persuasion. A registrar network puts your fixed price in front of everyone who tries to register something similar, which no broker can replicate. Brokers also decline most names they are offered, and a name that has been declined by two or three firms is telling you something about the buyer pool that is worth listening to rather than shopping around.

How to tell a real broker from a lead service

The market has a genuine problem with services that look like brokerage and are not. Warning signs: an unsolicited approach claiming a buyer is already waiting, a fee to have your name appraised or promoted, a guaranteed sale, pressure to sign quickly, and no named individuals with a traceable history in the industry. A real broker will decline names they cannot sell, name their commission plainly, and be uninterested in taking money from you before a sale. If the first conversation is about a payment you make rather than a buyer they know, it is not brokerage.

What to agree before you sign

Five things in writing. The commission and how it is calculated. Whether the mandate is exclusive and for how long, because exclusivity is normal but should be finite. The reserve price below which they cannot accept an offer. Whether a tail clause applies, obliging you to pay commission if you later sell to a buyer they introduced, which is reasonable in principle and sometimes drafted very widely. And who holds the domain and the funds during the transfer, which should be an escrow arrangement rather than the broker's own account.

What a broker cannot do

A broker cannot make a name valuable, cannot create a buyer who does not exist, and cannot conjure a price from a market that has no demand. If a name is worth $800, a broker will not make it $80,000, and any firm suggesting otherwise is selling you optimism. The honest thing a good broker offers on a mediocre name is a decline. Take it as free market research rather than a rejection, and price the name for a marketplace instead.

The realistic timeline

Brokered sales take weeks to months, not days. Research and outreach alone take a few weeks on a name worth pursuing, and corporate buyers move at the pace of their own approval processes, which can add a quarter on its own. Anyone promising a fast brokered sale is either sitting on a buyer already, which is possible and worth asking about directly, or telling you what you want to hear. If you need money this month, an auction is your venue and the discount is the price of the speed.

Key takeaways
  • A broker approaches buyers directly; a marketplace waits for them.
  • Expect roughly 15–20% commission, success-based, on a sell-side mandate.
  • Worth it above roughly $25,000, or when the buyer pool is small and known.
  • Real brokers decline names and never charge to appraise or promote.

Frequently asked questions

What does a domain broker do?

A broker researches which companies would want your domain, approaches decision-makers directly, and negotiates on your behalf. Unlike a marketplace listing, the outreach is active and the buyer never learns how motivated you are.

How much do domain brokers charge?

Typically 15% to 20% of the sale price on a sell-side mandate, success-based, sometimes tapering on larger deals. Buy-side work is often a fixed fee or a percentage of the purchase price, occasionally with a retainer credited against commission.

Is a domain broker worth it?

Above roughly $25,000, usually yes, because a better negotiated outcome outweighs the commission. Below about $10,000 the arithmetic rarely works and a marketplace listing will reach the same buyer for less.

How do I know if a domain broker is legitimate?

Real brokers decline names they cannot sell, state their commission plainly, and never charge upfront to appraise or promote a domain on the sell side. Unsolicited approaches claiming a buyer is already waiting are the most common scam pattern.

How long does a brokered domain sale take?

Weeks to months. Research and outreach take a few weeks, and corporate buyers move at the pace of their own approval processes. Anyone promising a fast brokered sale is either sitting on a buyer already or overselling.

What is a buy-side domain broker?

One who approaches a domain owner on your behalf when you want a name they already own. The value is anonymity: an enquiry from a company email address usually raises the asking price immediately.
