What a referral programme is, and how it differs from affiliate

A referral programme is a direct arrangement where a business rewards its own customers, or a defined circle of introducers, for bringing in a specific new customer they can name — as opposed to an open affiliate network paying anonymous publisher traffic. It's usually run in-house or through a dedicated referral tool rather than a network, because the relationship is with people who already know the product, not with content sites competing for search rankings.

That distinction matters for how a programme is built. An affiliate deal has to work for a stranger who has never used the product; a referral reward only has to be enough to make an existing, satisfied customer bother sharing a link. See referral vs affiliate for the fuller comparison of when each model fits, and how to build a referral programme for a step-by-step launch sequence — this page focuses on the reward structures, software and compliance decisions that sit underneath both.

Reward mechanics are the current European norm across referral tools; specific amounts are illustrative and vary hugely by margin and customer lifetime value.

Designing a reward that gets used, not left in an app notification

The single biggest driver of referral participation isn't the reward amount — it's how many steps stand between having something to share and actually sharing it. A reward that requires logging into an account, finding a hidden referral page and copying a link loses most of the customers who would otherwise have referred someone in the moment they were talking about the product.

One-sided vs two-sided

One-sided programmes, where only the referrer is rewarded, are cheaper per referral but recruit fewer people to act, because the friend on the receiving end has no immediate reason to convert quickly. Two-sided programmes cost more per acquisition but tend to convert referred leads faster, since the friend is getting something too — not just a recommendation, but a discount attached to it.

Cash, credit or gift

Credit suits any business that wants the reward to circle back into revenue rather than leave the business as cash; cash suits businesses — particularly B2B ones — where the referrer may not be a repeat buyer themselves, such as a consultant referring a client to a software vendor they don't personally use.

Setting the threshold and the cap

Most programmes pay out only once the referred customer has completed a qualifying action — a paid order, not just a sign-up — to avoid rewarding referrals that never convert to revenue. A cap on the number of paid referrals per customer per period, or a manual review above a certain reward value, is standard practice to limit fraud from customers gaming their own link with fake accounts.

B2B referral programmes run on different maths

A B2B referral programme has to reward introducers for deals with far higher variance in value than a consumer purchase, so flat consumer-style rewards break down once contract sizes climb. A common European pattern is a flat cash reward — commonly in the low hundreds of euros — for smaller-ticket software or services deals, moving to a percentage of first-year contract value, often around 10%, once deal sizes reach the tens of thousands of euros. Both figures are illustrative benchmarks reported across SaaS referral guides rather than fixed rules, and the right number depends entirely on gross margin and typical sales-cycle length.

B2B referrers are also frequently not the end buyer themselves: a consultant, an existing customer's champion inside a larger account, or a partner agency may refer a deal they'll never personally use. That means the reward has to work as a stand-alone incentive rather than assuming the referrer will also benefit as a user — which is one reason cash and gift cards dominate over account credit in B2B referral schemes. See B2B referral programmes for how European software and services companies structure tiered rewards, sales-team involvement and partner-adjacent referral schemes that blur into a lightweight reseller relationship. For reward benchmarks specific to a vertical rather than B2B generally, programmes by niche covers what performs by sector.

A referral reward only has to beat the cost of acquiring the same customer through paid channels — it doesn't need to feel generous in isolation, just competitive against what the business already spends on customer acquisition.

Referral software: what the market actually offers

Below a few dozen referrals a month, a simple unique-code system and a spreadsheet can work. Past that, dedicated referral software earns its cost by handling link generation, fraud checks, multi-channel sharing and payout automation without engineering time.

Consumer and D2C-focused platforms

Mention Me, a UK-founded platform, is the most established referral specialist across European retail, travel and fashion brands, built specifically around localisation and reward compliance across multiple markets. ReferralCandy targets smaller e-commerce merchants, mainly on Shopify and similar platforms, with a lighter setup and lower entry price than enterprise tools. Referral Rock positions itself more broadly across e-commerce, services and B2B, with more customisation of referral, affiliate and partner-style campaigns than the pure D2C tools.

Enterprise and rules-engine platforms

Talon.One is a promotion engine rather than a referral-only tool — it handles referral, loyalty and discount logic together, which suits larger retailers running referral rewards alongside other promotions rather than as a standalone programme.

B2B-specific tools

Cello and similar B2B-focused platforms build referral flows directly into a SaaS product's UI, prompting customers to refer inside the app itself rather than through a separate referral page or email, and integrate with CRM systems to attribute closed-won deals back to the referrer. That in-product placement is one of the more consistent findings in B2B referral design: asking at the point of active product use converts better than an email campaign asking customers to think back to who they know.

GDPR: the friend's data is the part that trips people up

A referral programme cannot legally hold onto a referred friend's contact details — name, email or phone number — until that friend has given their own consent, because the referrer consenting on their behalf doesn't satisfy GDPR's requirement that consent be freely given by the data subject themselves. This is the single most common compliance mistake in referral design: importing a friend's email address into a CRM the moment a referrer submits it, before the friend has agreed to anything.

The practical fix used by most compliant European programmes is to have the platform facilitate an introduction rather than store the friend's details directly — the referrer sends a personalised link or message through the tool, and the friend's data only enters the business's systems once they act on it themselves (typically by signing up or making a purchase). Once that happens, standard GDPR rights apply as with any customer: access, rectification, erasure and the right to object, all under Articles 15–21.

Referral rewards paid directly by a business to its own existing customers generally sit outside the DAC7 platform-reporting regime that applies to marketplaces and affiliate-style platforms intermediating third-party sellers, since the referrer isn't selling goods or services through the business's platform — but the distinction can blur for partner-style B2B referral schemes that pay introducers who behave more like independent agents, and those are worth checking against local guidance rather than assuming exemption.

Measuring whether a referral programme is actually paying for itself

The two numbers that matter most are cost per acquired customer through referral versus other channels, and the viral coefficient — how many new referrers each successful referral produces in turn. A programme with a healthy reward-to-margin ratio but a viral coefficient well below 1 is still just another paid-acquisition channel, not a compounding one; it needs to be judged on cost efficiency alone rather than on any expectation of self-sustaining growth.

Participation rate — the share of eligible customers who make at least one referral — and time-to-payout both affect whether a programme keeps working after the launch spike fades. A programme that converts well in its first month but sees participation collapse afterwards usually has a friction problem, not a reward problem, which is why how to build a referral programme puts as much weight on the sharing mechanics as on the reward itself. For businesses weighing whether the same budget would do more through an open affiliate network or a recurring-commission SaaS programme instead of a closed customer-only scheme, the honest answer is usually that they solve different problems and the strongest European growth programmes run more than one in parallel.

Quick answers

Can we import a referred friend's email address before they sign up?

No — under GDPR, a friend has to give their own consent before a business processes their personal data, so most compliant programmes have the referral tool send an introduction on the referrer's behalf rather than importing the friend's details directly into a CRM.

Is a two-sided reward always worth the extra cost?

Not automatically — it typically doubles the cost per acquisition, so it's worth it when the conversion lift from rewarding the new customer too outweighs that extra spend, which is usually the case for purchases with reasonable margin and a real decision-making friction to overcome.

Do B2B referral rewards need to be paid to a company rather than a person?

It depends on who the introducer is: an individual employee referring informally is usually paid personally, while a formal partner or agency referral relationship is more often invoiced business-to-business, which changes the VAT and reporting treatment involved.
