A referral fee is a payment made to someone who sends you a new client or deal. The amount varies a lot by industry, from a flat sum of a few dozen euros to 25% or more of a commission or first invoice. This guide walks through typical rates by sector, how tax treatment works, and a method to set a fair fee for your own business.

The gist: The right rate depends on your margin, your client lifetime value, and whether the referral partner brings a one-off lead or an ongoing stream.

What is a referral fee?

A referral fee is money paid to a person or business that introduces a new client or deal to a professional, in exchange for that introduction. It rewards the act of connecting two parties, not the work of delivering the service itself.

The terms get mixed up often, so it helps to separate them. A referral fee is usually a one-off payment tied to a specific introduction. A commission is ongoing pay tied to sales performance, often for someone actively selling on your behalf. An affiliate payout sits in between: it is usually automated, tracked through a link or code, and paid per transaction rather than per relationship. In French-speaking markets, the person who sends business is called an apporteur d'affaires, a term close to "referral partner" or "introducer" in English, and "finder" when the agreement specifically pays a finder's fee for sourcing a deal.

Who pays whom depends on the setup. In most professional services, the professional who receives and closes the deal pays the referral partner, usually after the deal is signed or the payment is collected, not simply after the introduction happens. This "trigger event" matters a lot, and we come back to it later: paying too early creates disputes if the deal later falls through.

What is a typical referral fee by industry?

Referral fee percentages and amounts differ sharply from one profession to the next, mostly because margins and regulation differ.

Real estate

In real estate, a referral fee is usually a percentage of the agent's commission, not of the sale price. The referring agent sends a buyer or seller lead to another agent, often in a different city or country, and receives a cut once the deal closes. Rates commonly sit in the 20% to 35% range of the receiving agent's commission, though this varies by market and by the relationship between the two agents. Some brokerages set a flat percentage for all referrals to keep things simple across their network.

Legal (attorney referral fee)

Attorney referral fees are more tightly regulated than in most other sectors, because bar associations in many jurisdictions place rules or caps on how lawyers can split fees for referring a case. A referral in this context usually means one lawyer sends a case to another lawyer better suited to handle it, and receives a percentage of the fee once the case resolves. This is different from "co-counsel fee splitting," where two lawyers actively work the case together and split the fee based on work performed, not simply on the introduction. Because rules vary by jurisdiction, lawyers need to check their local bar association's requirements before agreeing to a specific percentage.

Insurance, credit, and wealth management

In insurance and credit brokerage, referral fees often take the form of a fixed amount per qualified lead, or a percentage of the first-year premium for insurance policies. In wealth management, referral agreements sometimes tie the fee to a percentage of assets under management (AUM) brought in by the referral partner, paid as a one-off or spread over the first year. Credit brokers frequently use a fixed fee per funded loan rather than a percentage, since loan amounts can vary widely and a flat fee is easier to agree on upfront.

Consulting, agencies, and freelance services

Consultants, agencies, and freelancers typically pay a percentage of the first invoice, somewhere between 10% and 20%, when a referral partner brings in a new client. Some agencies extend this to a smaller percentage of the ongoing retainer for the first few months, as a way to reward referral partners who bring recurring clients rather than one-off projects. Others keep it simple with a flat fixed fee per signed client, regardless of the contract size, to avoid complex calculations each month.

Industry Typical structure Common range
Real estate Percentage of agent's commission 20% to 35%
Legal Percentage of case fee, capped by bar rules Varies by jurisdiction
Insurance Fixed fee or % of first-year premium Case by case
Wealth management % of AUM or flat referral bonus Case by case
Consulting / agencies % of first invoice or fixed fee 10% to 20%

How do you decide the right referral fee for your business?

The right referral fee for your business comes from your own margin and client value, not from copying another industry's rate. A fee that looks generous in real estate might be unsustainable for a freelancer with thin margins, and a flat fee that works for a consultant might feel insulting to a mortgage broker handling large deals.

Start with three numbers. First, your margin on an average client, after delivery costs. Second, your client lifetime value, meaning what a client is worth to you across the full relationship, not just the first invoice. This matters because research from the Journal of Marketing Research shows that customers acquired through referral programmes tend to show higher margins and lower churn, but this advantage holds only as long as the person who referred them also stays a customer. Third, test a few scenarios with the referral ROI calculator to see how different fee levels affect your net gain per referred client.

Once you have those numbers, the choice between a fixed amount, a percentage, or no commission becomes clearer. A fixed amount works well when your deal sizes are similar and predictable, such as a standard consulting package. A percentage works better when deal sizes vary a lot, such as real estate or credit brokerage, because it scales naturally with the value of what is being referred. No commission at all can still make sense for casual referral partners who refer out of goodwill or reciprocity, as long as you still track and thank them, since an unrewarded but valuable source can quietly stop sending business if ignored for too long.

Example: an accountancy firm with a 30% margin and an average client worth 2,000 euros in year one decides to pay a 15% referral fee on the first invoice, roughly 300 euros, and nothing after that. This keeps the fee simple, protects margin, and still gives referral partners a clear, immediate reward.

Is a referral fee taxable?

A referral fee counts as taxable income for the person receiving it, in most tax systems, whether the payment is occasional or part of a regular activity. The exact reporting obligations depend on the recipient's status and local tax rules, so this is general guidance rather than tax advice for a specific country.

There is usually a meaningful difference between an occasional referrer, such as a friend who sends one client a year, and a professional apporteur d'affaires who refers business regularly as part of their activity. The latter may need to register as a business or report the income differently, since tax authorities often look at frequency and intent to determine whether the activity is a hobby or a professional service. A written agreement helps both sides here: it documents the fee, the trigger event, and the amount, which matters if either party needs to justify the payment to a tax authority later.

How do you set up a referral fee agreement?

A referral fee agreement should spell out the trigger event, the payment terms, exclusivity, and duration, in writing, before the first referral happens. The trigger event defines exactly when the fee becomes due: on signed contract, on first payment received, or on a later milestone such as case resolution. Vague trigger events are the single most common source of disputes between professionals and referral partners.

Payment terms should state the amount or percentage, the payment deadline after the trigger event, and the method of payment. Exclusivity clauses matter when a referral partner works with several professionals in the same field and you want to avoid them sending the same lead to a competitor. Duration matters for ongoing retainers: does the referral partner get paid only on the first invoice, or for a set number of months, or indefinitely as long as the client stays?

A verbal arrangement might work fine for a one-off favour between friends, but it creates real risk once money and expectations are involved. Disputes over "what we agreed" are far easier to avoid with a short written agreement than to resolve after the fact.

How do you pay and track referral fees without disputes?

Most referral fee disputes come from the same three mistakes: no tracking of who referred whom, late or forgotten payment, and an unclear trigger event. A referral partner who has to chase payment, or who cannot tell whether their lead has been noticed, tends to stop referring quickly.

A simple process avoids most of this: invite the referral partner with a clear link or code, log each referral as it comes in, confirm when the deal closes, and trigger payment automatically at that point. Spreadsheets can work for a handful of referral partners, but they break down fast once a professional works with a dozen partners across different commission structures.

This is where a dedicated tool like the Referaly web app helps: it lets a professional invite referral partners, track each recommendation step by step, and set the commission structure per partner, whether fixed, percentage, or no commission at all.

Frequently asked questions

What is an appropriate or reasonable referral fee?

A reasonable referral fee reflects your margin and the value of the introduction, not a universal number.

What is a typical referral fee percentage?

How much is a referral fee in real estate?

The exact rate depends on the market, the brokerage's policy, and the relationship between the referring and receiving agents.

How much is a referral fee for an attorney?

Attorney referral fees vary by jurisdiction because bar associations often set rules or caps on fee splitting between lawyers. The split usually reflects a percentage of the case fee once resolved, and lawyers should confirm current rules with their local bar association before agreeing to a rate.

Is a referral fee taxable income?

Yes, a referral fee is generally taxable income for the person who receives it, whether the payment is occasional or regular. Reporting obligations differ for occasional referrers versus professional apporteurs d'affaires, so checking local tax rules or a tax adviser is worthwhile.

How much should I pay for a referral?

Calculate your margin on an average client, factor in client lifetime value, and test a few fee levels with the referral ROI calculator before committing. A fixed fee suits predictable deal sizes, while a percentage suits businesses where deal value varies widely.

Setting a fee that lasts

A referral fee only works long term if both sides see it as fair. Pay too little and referral partners stop sending leads. Pay too much relative to your margin and the programme eats into profit on every deal. The method here, starting from your own numbers rather than a borrowed industry average, gives a fee that holds up over time.

As Kumar, Petersen and Leone's research on customer referral value puts it, profitability is maximised by managing each client on two values at once: what they buy, and what their referrals are worth. Getting the fee right, then tracking it properly with a tool rather than a spreadsheet, is what turns referrals from an occasional favour into a steady source of clients.
