Posnic is open-source EPOS system built for real shops: supermarkets, restaurants, boutiques, pharmacies and hardware stores. Businesses in London run it free of charge, offline first, with every sale stored on their own machine.
Checkout in London 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 with inclusive or exclusive pricing, printed correctly on every receipt.
Prices, receipts and reports display in pounds with local number formatting, configured once per store.
Scan-and-sell with barcode scanners, or tap through sales on touch screens and tablets. Both are first-class.
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.
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.
