Offline POS and the Windows POS app

When the internet drops, the till keeps selling: sales are stored on the device and sent automatically when the connection returns. Windows app (.exe) and installable browser app.

The «🧾 POS» keeps working when the internet drops. Products, prices and the open shift are kept on the device; you keep selling, and the receipt shows a temporary number (OFF-…) and «OFFLINE — not synced». As soon as the connection is back, sales are sent to the server automatically and only then deducted from stock. Unsent sales survive a page refresh and closing the browser or the computer.

Prepare the till for offline work (once, while online)

«🧾 POS» → «Download the POS app». Two options: the Windows app (.exe) or «Install app» from the browser. Both work offline. The same block is in Settings → «🧾 POS registers».

Open the till, sign in, choose the register and open the shift. Products and prices are saved automatically (refreshed each time the till opens).

Done — if the internet drops, sales continue.

When the internet drops

A yellow bar appears at the top: «Offline — N sales not sent».

Sell as usual: barcode, name or the «Products» panel; cash, card or mixed payment. The receipt prints with a temporary number.

When the connection returns, sales are sent automatically (or press «Send now»). The server checks prices against its own data; each receipt is recorded only once.

NOT available offline: opening and closing the shift (Z), X-report, returns, choosing a customer, wholesale price, IMEI / serial items and free-text lines. The shift cannot be closed while unsent offline sales remain — the connection must return first.

If stock is short (e.g. another till sold the same item while offline), the offline sale is still accepted, the item goes to negative stock and admins plus users with «POS — edit» permission get a notification. Online sales are unchanged — an item without stock cannot be sold.

Windows POS app

Click «Download for Windows (.exe)» and open the file. Windows may show an «unknown publisher» warning: «More info» → «Run anyway».

On first launch enter your company address (e.g. yourcompany.crm.sbt.az or crm.sbt.az). Settings also let you pick a printer, use full screen and start with Windows.

The app sends receipts straight to the printer without a preview. It opens and keeps selling without internet.

The app updates itself: a new version downloads in the background and a «A new version is ready — restart» notice appears. Finish the sale and click «Restart»; if you don't, it installs when you close the app. The POS page itself is always the latest version. If you installed version 0.1.0, download the new version manually once — later updates are automatic.

SBT CRM works together with the online cash register (NKA): the sale is made in the CRM, the fiscal receipt is printed by the device and its number is linked to the sale. Receipts without a number are shown separately in the Z-report, and only a manager can change the number later. Direct integration with Omnitech cash registers is being prepared — once connected, receipts will be issued automatically.
