Berlin shops choose Posnic because it treats reliability as the product: billing works through any outage, data stays local, and the entire POS (Kasse) software is free and open source under AGPL-3.0.
Run one shop or a chain across Germany: each store keeps its own settings, consolidated in cloud dashboards when you subscribe.
The complete application is public on GitHub under AGPL-3.0. No trial, no feature locks, no telemetry.
Everything lives in a local database you control, exportable to CSV any day, with a documented sync protocol.
Thermal receipt printers, barcode scanners, label printing, weighing scales and cash drawers are all supported.
Checkout in Berlin never waits on the internet. Posnic runs on the shop computer, keeps billing through any outage, and syncs later if you use Posnic Cloud.
Configurable tax groups handle VAT (MwSt) with inclusive or exclusive pricing, printed correctly on every receipt.
