Keep your customers coming back with a digital stamp card.
- Your customers collect stamps on their phone.
- They come back for their reward.
- You see who came and who stopped coming.

Grella is a digital stamp-card loyalty platform for small businesses in Peru.
Customers who don't come back don't tell you.
They go to a competitor and you never find out. A paper card won't tell you either: it gets lost, stamped twice, and never says who it was.

Any questions?
Do my customers have to download an app?
No. They scan the QR with their phone's camera and their card opens in the browser. It works on any Android or iPhone.
What do I need to get started?
A phone with a camera at the counter to give stamps, and your printed QR. We set it up with you, at your business.
How much does it cost?
S/ 119 + IGV a month per location, with a 30-day free trial and no card. Each additional location costs half.
What data do you ask my customers for?
Only three things: name, phone and email. We don't use them for advertising or share them with other businesses.
Can I change the reward later?
Yes. Customers already collecting stamps finish their card under the rules they started with; the change applies from their next card.
Does it work if I have more than one location?
Yes. Each location has its own QR, and your customers collect stamps at any of them, on the same card.
