How do I thank customers who refer friends on WhatsApp?

Send a short thank-you the same day and give a small treat on their next order. Say what the reward is before the friend orders, so nobody argues later.

• Ask the new customer who told them about you, so you know who to thank.
• Pick one simple reward you can afford: a free drink, a small dish or a little off the next order.
• Tell the regular customer in writing what they will get and when.
• Give the reward once the friend has actually ordered, not when they only message.
• Do not send the same reward to many people at once. Keep it for real referrals.
