About fritz-kola®
fritz-kola started with a simple question: Can’t we do better?
Two friends, a student dorm in Hamburg-Othmarschen, and a few thousand euros in startup capital — that’s all it took to lay the foundation for one of Germany’s most iconic beverage brands in 2002.
In 2003, Mirco and Lorenz delivered the first crates of fritz-kola in a beat-up van — using small glass returnable bottles instead of giant plastic containers. fritz-kola has always stood for high quality and a bold attitude. And when it comes to point-of-sale systems, their mindset is the same: there must be a better way.
The challenge: A compliant and fast launch with Shopify POS
When fritz-kola made the spontaneous decision to open a new popup store, one thing was clear: they needed a POS system that was not only quick to set up but also legally compliant. Since their online shop already runs on Shopify, using Shopify POS was the natural next step.
But in Germany, every in-person sale via Shopify POS must be signed using a certified TSE (technical security system) in accordance with KassenSichV regulations — otherwise, you risk fines or inquiries from the tax office.
On top of that, the upcoming 2025 obligation to register POS systems and a seamless integration with accounting were crucial requirements. fritz-kola was already using Pathway Solutions for accounting, which made the integration smoother.
What fritz-kola was looking for:
A legally compliant Shopify POS solution
Fast implementation without complex technical setup
Reliable guidance on fiscalization and hardware
A partner that operates on equal footing
Proper handling and accounting of deposit (Pfand) amounts from day one
The solution: Fully compliant Shopify POS with OpenFiskal — in just a few days
Within a matter of days, the new popup store was up and running with full fiscal compliance thanks to OpenFiskal. Even the required POS registration was handled directly via OpenFiskal and Meldefluss, using a generated ELSTER-compatible export file — fully ready for the upcoming legal mandates.
Our team supported fritz-kola throughout the entire journey — from first consultation to final activation:
Clarification of all hardware and system requirements
