Description
A small shop's nightmare is a POS that dies the moment the network drops — the till can't ring up a single sale and customers pile up at the counter. Most cloud POS systems also bill monthly and take a cut of turnover, which adds up over a year. Posnic flips this: the database and API run on the till computer itself, so you keep ringing sales, tallying and printing receipts even offline — a connection is only needed for optional things like electronic payments and cloud backup.
It's an Electron desktop app for Windows, macOS and Linux, covering both retail shops and restaurants: barcode checkout, inventory, daily reports, multi-role permissions. The desktop packages have no trial clock and a zero software price, the source is AGPL-3.0, and the local edition needs no account and — per its published privacy policy — sends no telemetry. To try it first, the site has a real supermarket demo that resets on the hour (log in as admin/admin) where you can ring up sales and break things freely.
Offline-first: The primary database and API sit locally on the till, so ringing sales, checkout and receipt printing keep working when the network is down; connectivity is only for electronic payments and optional cloud services.
Retail and restaurants: One app serves both barcode checkout for shops and order-taking for restaurants, with a product grid, categories, parked bills and recent sales in the checkout screen.
Inventory management: Items, stock and purchasing in one place — stock drops as you sell, and daily reports show each day's sales, costs and cash.
Cross-platform desktop: Built on Electron with packaged installers for Windows / macOS / Linux, able to drive receipt printers, barcode scanners and cash drawers.
Local data · no subscription: The desktop edition has no trial period and a zero software price, the local edition needs no Posnic account, and the privacy policy states no telemetry is sent.
Open source · self-hostable: Posnic's own source is AGPL-3.0 — read it, modify it, self-host and fork it (release packages also bundle separately licensed third-party components to review on their own).
