Install the desktop POS app
The Windows register app — built-in thermal printing, offline selling, and a sync engine that catches up when you're back online.

SYEZPOS runs in a browser, but registers do better on the desktop POS app — it keeps a local copy of your catalog on the machine, prints receipts without the browser's print dialog, and keeps selling through internet drops.
Why the app over the browser
- Silent receipt printing — receipts go straight to the thermal printer, no print dialog between the customer and their change.
- Real offline selling — the catalog, customers and held sales live on the register itself. Sales made while offline queue locally and sync when the connection returns.
- Sync status built in — the app reports what it's pulled, pushed and still has pending.
Install
- Get the installer from your SYEZPOS onboarding — it isn't a public download.
- Install and open it — the app signs in with the same staff account as the browser.
- Sign in, pick the register this machine is, and let the first sync pull your catalog down.
- Open printer setup and pick the receipt printer — the app prints directly to it.
Tip: One app install per physical register. Each machine signs into its own register so day close counts stay honest per till.
Keep it syncing
Offline sales upload while the app is open and online. If a machine's been off-network a while, leave the app open after reconnecting until the pending count clears — see offline & sync issues if it stalls.
