Referral selling: why “Do you know anyone else?” almost never works
Building referral selling systematically in B2B: the right moment to ask, specific instead of open referral questions, the introduction made by the customer, rewards without an aftertaste — and what § 7 UWG and the German Federal Court of Justice say about calls and emails to referred contacts.
The short answer
Referrals do not happen on their own, not even with satisfied customers. They happen when three things come together: the right moment, a specific question and an easy way to make the contact. The open question at the end of a meeting — “Do you know anyone else who might be interested?” — almost always gets the same answer: “Nobody comes to mind right now.” In sales teams in energy, retail and payments I have seen referrals become predictable once they are treated like any other sales activity: with a fixed moment, fixed wording and a field in the CRM.
The moment: after the benefit, not after the signature
Right after closing, the customer has experienced nothing except your promise. Asking for referrals at that point means asking them to pass their own risk on to people they know. Few will.
Better moments, each as an example:
- After the first noticeable effect: the first monthly statement that comes in lower; the terminal that has run for four weeks without an outage.
- After a solved problem: a customer you helped on a Saturday evening is never more willing to refer than on the Monday after.
- When the customer thanks you: that is the invitation. Most salespeople say “you’re welcome” and let it pass.
Define these moments and set follow-up reminders, for example 30 and 90 days after go-live. What is not in the calendar does not happen.
The question: specific instead of open
Faced with an open question, your customer’s brain searches their entire circle — and therefore finds nobody. Narrow the search:
“You’re in the bakers’ guild. Is there anyone there who is currently complaining about their card payments?”
“Who is your neighbour on the high street that you swap notes with on topics like this?”
“You mentioned your brother-in-law also runs a business with two branches. Does he have a similar issue?”
The question names a group, a place or a specific person the customer mentioned themselves. That is why it pays to listen in the first meeting to who the customer is connected with — the first-meeting structure delivers this information along the way.
The handover: the customer introduces, not you
A referral that ends up as a name and phone number on your notepad is just slightly warmer cold calling. An introduction made by the customer is far stronger:
“Would you be comfortable sending Mr Example a short note saying I may get in touch? I’m happy to draft two sentences for you.”
Then deliver those two sentences — short, free of marketing language, in your customer’s tone. This has two advantages: the referred person expects your call, and you have a basis for the contact that holds up legally.
What the law says
Your customer’s referral is not the referred person’s consent. § 7(2) no. 1 UWG requires at least presumed consent for a promotional call to a business, and prior express consent for a call to a consumer. Under § 7(2) no. 2 UWG, advertising by email always requires the addressee’s prior express consent, in B2B too.
“Refer a friend” features, where your customer triggers a referral email to third parties via your website, are particularly delicate. In 2013 the German Federal Court of Justice ruled (I ZR 208/12) that the company is liable for such emails as if they were its own advertising. In practice, that means:
| Route | Assessment |
|---|---|
| Customer writes or calls themselves, referred person says “have them get in touch” | clean, and the most effective in sales |
| You call a referred business with a concrete, factual reason | possible in B2B if presumed consent can be justified — see cold calling by phone |
| You call a referred private individual without their consent | not permitted |
| Referral email via your website or from you to the referred person | not permitted without the recipient’s express consent |
This is not legal advice. Anyone setting up a referral programme with forms or rewards should have it checked by a lawyer once.
Rewards: open or not at all
Rewards amplify referrals that would have come anyway. They do not create any where the customer is not convinced. If you pay a reward, do it so that the referred person knows. A hidden reward damages trust as soon as it comes out — and among small businesses, it does come out. Whether the reward is taxable for the recipient is for the tax adviser to clarify, not the salesperson.
A model calculation with freely chosen figures to gauge the order of magnitude: a new customer brings a contribution margin of 40 euros a month and stays three years on average. That is 1,440 euros over the term. A reward of 100 euros is small by comparison. The bigger question is whether your service is good enough that the referring customer does not feel embarrassed three months later.
Making referrals measurable
Create a field “Source: referral from …” in the CRM and review it monthly. Three metrics are enough:
- How often did we ask? Most teams massively overestimate this number.
- How many contacts came out of it?
- How many of those became customers, and how long do they stay?
If the first number is low, the problem is not the customer. A CRM field nobody maintains does not help — how to make upkeep easy is covered in a CRM salespeople actually use.
What you can do this week
- Define two fixed referral moments, for example day 30 and day 90 after go-live, and set them up as reminders.
- Write three specific referral questions for your target group and share them with the team.
- Prepare a two-sentence introduction text that customers can forward.
- Review or switch off “refer a friend” forms and referral emails.
- Introduce the CRM field “Source: referral” and maintain it from now on.
- Thank every customer who has referred someone personally — regardless of whether a deal results.
