Installation
QuickPOS is a desktop app that runs entirely on your local network. No internet required, no subscriptions, no cloud — your data never leaves your premises.
Why local is better
Most POS systems run in the cloud — your sales data travels to a third-party server every time you take a payment, you pay a monthly subscription to access your own data, and if the internet goes down your till stops working.
QuickPOS works differently. It runs directly on a PC on your premises and all other devices — tablets, phones, customer displays, kitchen screens — connect to it over your local Wi-Fi. Nothing leaves your building.
- ✓ Works without internet — your till never goes down because of a broadband outage
- ✓ No subscription fees — pay once, own it forever
- ✓ Your data stays yours — no third party ever sees your sales, customers or products
- ✓ Instant response — everything runs on your network so there is no server round-trip latency
- ✓ One till serves the whole venue — all devices connect to the same server in real time
What you get
QuickPOS is distributed as a desktop app — a single installer file for your platform. Double-click it, install it like any other app, and it is ready to use. No Node.js, no terminal, no technical setup required.
| Platform | Installer |
|---|---|
| Mac | QuickPOS-x.x.x-universal.dmg — works on both Intel and Apple Silicon |
| Windows | QuickPOS-x.x.x-x64.exe — standard Windows installer |
| Linux | QuickPOS-x.x.x-x64.AppImage or .deb |
Installing on Mac
Double-click the downloaded .dmg file. A window opens showing the QuickPOS icon and your Applications folder.
Drag the QuickPOS icon into the Applications folder shortcut in the same window.
Find QuickPOS in your Applications folder and double-click it. On first launch macOS may show a security prompt — right-click the app and choose Open, then click Open again to confirm. You only need to do this once.
Installing on Windows
Double-click the downloaded .exe file. If Windows SmartScreen shows a warning, click More info then Run anyway. This happens because the app is new — it is safe to proceed.
The installer runs silently and places QuickPOS in your Start Menu and optionally on your desktop.
Open it from the Start Menu or desktop shortcut.
Setting up your network
QuickPOS runs a local server on the till PC. Every other device in your venue connects to that server over Wi-Fi — no configuration required on the other devices, just open a browser and enter the address.
http://192.168.1.10:3000. Share this with any device that needs to connect.Devices that can connect over Wi-Fi include tablets for a second till point, phones for mobile ordering, a TV or monitor for the customer display, and a dedicated screen for the kitchen or stockroom order display.
First run
When QuickPOS opens for the first time it runs a short setup wizard to configure your admin PIN and optionally add staff members. This takes about a minute and only happens once — all your settings, products and orders persist between sessions automatically.
See Security & PINs for more detail on the PIN system.
Where your data is stored
QuickPOS stores all your data in a folder on the till PC. The location depends on your platform:
| Platform | Data location |
|---|---|
| Mac | ~/Library/Application Support/QuickPOS/data/ |
| Windows | %APPDATA%\QuickPOS\data\ |
| Linux | ~/.config/QuickPOS/data/ |
This folder contains your products, categories, orders, settings and held sales — all stored as plain JSON files. See Data & Backup for backup guidance.
Updating QuickPOS
When a new version is available, download the installer and run it. The installer replaces the application files automatically. Your data folder is never touched during an update — all your products, orders and settings remain exactly as they were.
