Ultimate POS Desktop — Brand your own offline-first POS app

See it in action

Watch the demo, then try it yourself

Two minutes of the desktop POS doing real work — then download the demo app, sign in with one click, and put it through its paces.

Features

A desktop POS that keeps selling when the internet doesn't

A 1:1 replica of the UltimatePOS sell screen, engineered for the counter — fast, offline, and hardware-ready.

⚡

Offline-first

Sell, print and reconcile with zero connectivity. Every sale is queued locally and syncs the moment you're back online — no lost transactions, ever.

🖨️

Silent receipt printing

Bundled QZ Tray with a pre-trusted certificate. Receipts, KOT and BOT print instantly — no browser dialogs, no per-terminal setup.

🧾

Full parity

Cart, discounts, taxes, lots/FEFO, service staff, tables, drafts, quotations, suspended sales, registers, reward points — exactly like the web POS.

🔄

Free auto-updates

Signed delta updates delivered automatically. Your customers always run the latest build — you never touch a terminal.

🎨

Your brand on the glass

Your name, your logo, your URL. Every app we compile is white-labelled — it's your product, not ours.

🔒

Code-signed installers

Windows/macOS installers, signed and (on macOS) notarized, so they install clean without scary warnings.

How it works

From logo to signed installer — in one sitting

No build servers, no signing certificates, no DevOps. Just your brand and a card.
