Posnic is open-source POS (caisse) software built for real shops: supermarkets, restaurants, boutiques, pharmacies and hardware stores. Businesses in Nice run it free of charge, offline first, with every sale stored on their own machine.
Run one shop or a chain across France: 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 Nice 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 (TVA) with inclusive or exclusive pricing, printed correctly on every receipt.
Posnic for your business: Grocery · Restaurants · Cafes · Fashion · Pharmacy · Electronics · Hardware
Posnic uses configurable tax groups, so VAT (TVA) rates are set once and applied automatically, with inclusive or exclusive pricing and tax-wise report summaries.
Any Windows computer. Standard USB barcode scanners, thermal receipt printers, cash drawers, weighing scales and touch screens all work. Existing hardware from a previous system usually carries over.
Yes. Each store runs its own offline Posnic, and Posnic Cloud syncs them with branch-level access control and consolidated dashboards you can watch from anywhere.
