Other freelancers are your best referral source

Somebody in your discipline turned down a €12,000 project last week because they were booked through November. They didn't post about it. They mentioned it to one person, and that person got the work.

That project is the through-line here. It gets passed three different ways in this post, and the three arrangements pay differently, carry different risk, and leave the client belonging to different people. Most freelancers treat all three as "a referral" and then discover the difference when an invoice goes unpaid.

The lead source itself is the least controversial part. A peer who is overbooked has already talked to the client, already knows the budget is real, and vouches for your standard when they pass it on. Three of the four hard parts of selling are done before you open your laptop. A client refers you maybe once a year; a busy freelancer in your field turns work away every month.

This post is about freelancer-to-freelancer work specifically. Getting onto a client's internal shortlist is a different mechanism and it has its own post.

Reciprocity works when it is specific, and not when it is announced

The failure mode is posting availability in a group of 400 freelancers. Nobody forwards a client to a name they half-recognize.

What works is eight to twelve people who could plausibly receive work you can do, contacted individually, with one sentence they could paste into an email. Not "let me know if anything comes up." Something a busy person can forward without thinking: "I do Webflow builds for B2B SaaS, three-week turnaround, currently free from mid-October."

The reciprocal half matters more than the asking half, and it's cheaper than it looks. When you turn work down, you spend two minutes naming someone rather than saying you're full. That costs you nothing and it is the entire mechanism by which people remember you.

Adjacent disciplines are the underrated group. A designer gets asked about developers constantly. A copywriter gets asked about SEO. Two or three good relationships across the boundary of your discipline produce more inbound than twenty inside it, because inside it you're competing and outside it you're completing. Peer referral is also the second-cheapest channel by hours invested per client won, behind only past clients, in where freelance work actually comes from in 2026.

Three ways that €12,000 project can reach you, and they are not the same deal

Here is where most of the confusion lives. "I'll pass you their details" and "I'll bring you in on it" are commercially different arrangements.

The third column is where the money question lives, and it's the one people accept without reading.

Two practical consequences. First, if you're being introduced rather than subcontracted, you own the credit risk, so the client screening is yours to do. Second, if you're subcontracting, the client is not yours afterwards, and quietly treating them as yours is how these relationships end.

What a referral fee should be, and the cap that makes it a decision

No credible data exists on typical referral fee levels in freelance work. Any percentage you've heard quoted is a convention that circulated, not a benchmark, and it should be treated that way.

What you can reason about is what the fee buys. The referrer's actual work is one email. What they're really transferring is a qualified buyer plus their own reputation as collateral. That has a value and it's computable: it is what winning a comparable client through your own pipeline costs you in unbilled hours.

That gives you a cap. If winning a client normally takes you eight unbilled hours of research, calls, proposal writing and follow-up, and your own rate is €90, the introduction saved you roughly €720 of unbilled time plus the risk of not winning at all. A fee above that number is worse than doing your own prospecting. A fee well below it is a good trade for both of you. Run a couple of your own finished projects through the effective hourly rate calculator with acquisition hours included and you'll have a real figure rather than an intuition.

Three structural rules regardless of the number:

Charge it on the first engagement only. A fee that continues on every project that client ever commissions is an annuity paid to someone who stopped being involved after the first email. It also creates a slow resentment that ends the relationship around project four.

Say when it's paid. On your invoice being paid, not on the contract being signed. Otherwise you can owe a fee on money you never received.

Consider paying it in work instead. Reciprocal referral is the normal arrangement between peers and it avoids the whole apparatus below. Cash fees make sense when the flow is genuinely one-directional.

If you do pay cash, it's a business expense and it needs the same paperwork as any other. In the US, payments for services of $2,000 or more in a year to a non-corporate payee are reportable on Form 1099-NEC, due to both the IRS and the recipient by 31 January. That threshold rose from $600 under Pub. L. 119-21 §70433 for payments made after 31 December 2025, which means smaller fees now generate no form at all and are still fully deductible and fully taxable to the person receiving them. Collect a W-9 before you pay; without a correct taxpayer identification number you are into backup withholding at 24%.

In the UK and EU, a referral fee is a supply of services, so a VAT-registered referrer should invoice you with VAT. Cross-border between businesses, the place of supply is where the customer belongs and you account for the VAT yourself under the reverse charge, per HMRC's place of supply notice. A referrer in Berlin invoicing you in Manchester should not be charging you German VAT.

Subcontracting: the prime's margin is a risk premium, not a markup

Now take the same €12,000 project as a subcontract. The overbooked freelancer holds the contract and brings you in. Illustrative numbers, not observed data, but the structure is what matters.

Say you bill the prime €8,000 and they keep €4,000. From the outside that looks like a third of the value for making an introduction, and subcontractors resent it on exactly that reading.

Work it through from the prime's side. They scoped the project, ran the client relationship, reviewed your work, absorbed one round of rework that the client asked for and you disagreed with, and chased the invoice. Eighteen hours is a conservative figure for all that on a project this size, and at €90 an hour it's €1,620 of the €4,000 gone. They also fund the gap: if they pay you on 30 days and the client pays them on 60, they carry €8,000 of somebody else's money for a month. And if the client never pays at all, they owe you €8,000 anyway.

So the real margin is closer to €2,380 for taking the credit risk on €12,000 and the delivery risk on work they didn't do. That is a risk premium. It is priced correctly when the prime can actually verify the client and wrongly when they can't.

Which tells you what to look at when you're offered a subcontract. Not the percentage. Ask what the prime is carrying, and whether their contract with the client protects them, because it's the only thing protecting you.

If you're on the other side and doing the subcontracting regularly, the operational shape changes: you need per-project budgets, someone else's hours landing against them, and financials visible to you but not to everyone. That's the studio setup rather than the solo one, and it's the point where per-seat pricing starts to matter. Harvest, for one, charges $9 per seat per month on its Teams plan, so every subcontractor you add carries a recurring cost of its own. The Harvest alternative page sets that against pricing charged per workspace rather than per seat, which is the difference that shows up when a two-person job becomes a four-person one.

Pay-when-paid moves the risk onto the person who can't see the contract

The single clause that decides whether a subcontract is safe: does the prime owe you when the work is accepted, or when their client pays them?

Pay-when-paid is common and generally enforceable in ordinary commercial services contracts. It also puts the credit risk on you, the one party who has never seen the client contract, doesn't know the payment terms and can't chase. You are lending money to a company you can't assess.

What to ask for, in order of how likely you are to get it:

• Payment on acceptance of your deliverable, not on the prime's receipt of funds. Fixed number of days, ideally 30.
• If it has to be pay-when-paid, a longstop date. Paid when the client pays, or 60 days after acceptance, whichever comes first.
• The client's payment terms disclosed before you start. If the prime is on 90 days and offers you 30, that's useful information about how much float they're carrying.
• A deposit on anything over a few thousand, on the same logic you'd apply to a direct client.

Your invoice to a prime is a business-to-business debt like any other, so the statutory entitlements apply to it. In the UK that is Bank of England base rate plus 8%, currently 3.75% plus 8% for the half-year to 31 December 2026, plus a fixed sum of £40 to £100. In the EU it is the ECB reference rate plus at least eight percentage points under Directive 2011/7/EU, with a minimum €40 per late invoice. You will probably never invoke this against a peer. Knowing it exists changes how you write the email at day 45, and the whole escalation is in the freelancer's guide to getting paid on time.

The twenty minutes of paperwork that keeps the friendship

Peer work is done on trust, which is exactly why it needs writing down. A dispute between friends without a document is worse than a dispute between strangers with one.

Four things, and none of them take long.

A short subcontract. Scope, price, payment trigger, payment days, what happens on cancellation, and who talks to the client. Two pages is plenty. The free contract generator produces a signable PDF in the browser with custom clauses and a signature block, no signup and no watermark.

The intellectual property chain. This one gets missed and it's the expensive one. The prime cannot assign to the client what they don't own. If your subcontract doesn't assign your work to the prime, their contract with the client is promising something they can't deliver, and that surfaces during an acquisition due diligence three years later. One clause, both directions.

Confidentiality, in writing, before the brief is shared. You're receiving another company's information through an intermediary who may already be under an NDA that doesn't cover you. A mutual or one-way NDA takes two minutes to generate.

Tax details up front. W-9 from a US subcontractor before the first payment, VAT number both ways if either of you is registered. Chasing this in January is how a €400 fee becomes an afternoon.

Thirty minutes now, and the list to build this month

In the next thirty minutes: write down the eight people who could plausibly send you work, and send two of them the one-sentence description of what you take on and when you're free. If any of them has already sent you something, tell them what it turned into. People send more work to someone who closed the loop.

This month: decide your referral fee position before anyone asks, so you're not negotiating it under time pressure. Compute your own cost per client won, cap any fee below that, and write your two-page subcontract template once so the next overflow project takes an hour of admin rather than a week of email. If the work you need is immediate rather than structural, the peer channel sits on day three of the seven-day plan.

Worklyn's projects hold budgets, time logs and costs against the same job, so when you're the prime you can see what the margin actually was after review and rework rather than assuming it was the difference between the two invoices.
