A referral fee is the percentage (or flat amount) a business pays the person who introduced a new client. Across professional services, a simple introduction typically earns 5 to 10% of collected first-year revenue, and the rate rises with involvement.
That one-sentence answer hides a lot of variation. Below are verified benchmarks by industry, what moves a fee up or down, and the one profession where standard advice doesn't apply.
Four patterns hold across every industry we've looked at:
Those numbers come from published programs and compensation surveys. The rest of this post breaks them down by industry.
Karl Sakas reports 5 to 10% of collected revenue as the standard range, with 10% being the most common number. Twelve-month caps are standard, and step-down structures (10% in year one, 5% in year two) show up frequently.
Among agencies that publish formal partner program rates, Promethean Research found a median commission of 20%. That's higher than the informal referral norm because those programs expect partners to actively sell, not just introduce.
Duration beats rate. A 10% fee paid for three years is worth 50% more total than a 20% fee paid once. If you're evaluating an agency partner program, look at the cap as hard as you look at the percentage. More on how agencies structure this on our agencies page.
Consulting Success puts the common range at 5 to 15%, inside a broader 3 to 20% spread. Where you land depends on involvement. A quick intro on a large engagement runs 1 to 5%. Heavy involvement in scoping and selling the project can justify above 15%.
Consultants tend to trade referrals informally, which means the fee often gets negotiated after the introduction instead of before. That works until it doesn't. Getting the rate and trigger in writing before the intro converts saves both sides an uncomfortable conversation later.
The typical structure is 5 to 10% of monthly recurring revenue for the first 12 to 24 months, paid only while payments arrive. If the client churns in month three, payments stop.
This is the model that breaks spreadsheets fastest. Each referral generates a payment obligation that stretches across a year or more of monthly invoices, and the fee needs to track against actual collected MRR, not the contract value. Multiply that by a handful of active referral partners and you've got a reconciliation problem that compounds every month. More on how MSPs handle this on our MSPs page.
This is the one profession where standard referral fee advice doesn't apply. ABA Model Rule 1.5(e) permits fee division between lawyers only when:
There's no "typical percentage" because the fee must be tied to actual work or responsibility, not a finder's commission. Non-lawyer fee sharing is separately restricted under most state bars.
For law firms, the documentation trail isn't optional. It's an ethics requirement. That makes tracking referred matters end to end more important here than in any other industry. See how firms handle this on our law firms page.
If you want a defensible number for your own program, the referral fee calculator publishes its math, and the partner earnings calculator shows what the program looks like from the partner's side.
Should the fee be on revenue or profit?
Revenue, almost always. Profit-based fees require sharing your cost structure with the referrer, which most firms won't do. Revenue is simple, verifiable, and standard across every industry in this article.
When should the fee get paid?
Within 30 days of each quarter-end, on revenue collected that quarter. Paying on collected cash (not signed contracts) protects you from paying commissions on invoices that never get paid. Quarterly is the most common cadence for professional services referrals.
Do I need a written agreement?
Yes. One page covering what qualifies as a referral, the rate, the payment trigger, the time cap, and the clawback terms prevents disputes that would otherwise be settled by memory. We publish a referral fee agreement template you can start from.
How do I keep track of what I owe?
That's the part that breaks spreadsheets. Referral obligations stretch across months or years, involve trailing payments against collected revenue, and multiply across partners. A handful of active referral partners with overlapping payment windows is enough to make manual tracking unreliable. Commission tracking and a partner portal where partners can see their own earnings handle this without the quarterly reconciliation scramble. Get started free →
