It started with a holiday by the coast
The idea came on vacation at the sea. Since 2023, 'n Eis zapfen has been a regular stop in Central Saxony for anyone who loves ice cream.
Ronny Heymann and Annett Adler opened their first shop in Frankenberg in April 2023. The concept: guests put their ice cream sundae together completely themselves. Nothing like it existed in the region.
Here's how it works: pick a cup (three sizes), fill it with soft serve from the machine, add toppings. Fruits, chocolate pieces, gummy bears, cornflakes. Kids love it, and adults do too.
The idea works. The family now runs three locations. Since March 2026, there's a new 'n Eis-Café on the market square in Hainichen: around 40 seats, homemade cake, hot drinks.
More than ice cream
Self-assembled sundaes, homemade cream puffs, Americano waffles with fresh fruit. If you're after something different, you'll find it.

Retain regulars digitally, but how?
With three locations and a growing customer base, the question came up: how do you get guests to come back regularly, without pulling out a paper card on every visit?
Before Treuli, the shop used a different loyalty system. Ronny and Annett wanted something they could set up and change themselves. This is their own experience and view:

Setting up and changing things themselves
In Ronny and Annett's view, swapping out a reward or changing a line of text should work without asking anyone first.
Only what the counter needs
In everyday use they mainly rely on two things: collecting points and redeeming rewards. By their own assessment, they don't need more.
Built for the counter
With Treuli, Ronny and Annett found a loyalty program they can set up and change themselves, and that does exactly what a café or ice cream shop actually needs.
Points via receipt
After a purchase, the customer scans the QR code on the receipt. Points land on the account automatically. Staff at the counter don't need to do anything extra.
Redeem rewards
Collected points get exchanged for rewards, from a free coffee to a large sundae. Rewards are listed by category in the app.
Welcome bonus and birthday gift
New customers get a handful of points on registration. On their birthday, another batch. Both run automatically.
Friends referring friends
Whoever recommends a new guest gets points. The new customer does too. It runs quietly in the background and regularly brings in new regulars.
Promotions and news in the app
Current flavors, upcoming deals, news: everything lands in the app. Links to the website and Instagram are right there.
