Posnic is open-source POS software built for real shops: supermarkets, restaurants, boutiques, pharmacies and hardware stores. Businesses in Bangkok run it free of charge, offline first, with every sale stored on their own machine.
Live stock with every sale, low-stock alerts, purchase receiving and a full movement history behind each number.
Table ordering, kitchen tickets and hybrid retail-plus-dining in the same software, at no extra cost.
Run one shop or a chain across Thailand: 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.
Posnic for your business: Grocery · Restaurants · Cafes · Fashion · Pharmacy · Electronics · Hardware
Posnic uses configurable tax groups, so VAT 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.
