A coffee shop without loyal customers is a treadmill. You run, spend on ads, and customers go across the street.
People drink coffee every day. A bonus program turns that into a habit of going specifically to you. 6 cashback tiers from 3% to 10% — customers actually compete for higher levels.
A welcome bonus of €1-2 motivates signups. A push an hour after the visit reminds them about their balance. Hasn't been in 2 weeks — automated "we miss you, here's a bonus." Birthday — a free coffee.
QR on the table + barista who offers = 15-20 signups per day. Repeat visits +35% in the first 3 months.
