Frequently asked questions

What kind of shops is Posaro for?

Retail and wholesale shops such as mini-marts, building-supply and spare-parts stores — with a dedicated toolkit for agricultural chemical shops. Restaurants that need table or kitchen-order features are not supported yet.

What is the difference between Cloud and On-premise?

Cloud keeps your data on our servers, supports multiple terminals and branches, and can be opened from anywhere. On-premise keeps data on your shop computer and suits shops with a single terminal.

Can I still sell if the internet goes down?

Yes. Terminals that have signed in before can keep selling with cash, QR or transfer and print receipts; bills sync automatically when the connection returns. On-premise does not need the internet to sell at all.

How do I pay?

Scan the PromptPay QR code and attach the transfer slip in the program or on the website. Once the slip is verified, your service is extended and you are notified by SMS or email.

Which hardware works with Posaro?

Any keyboard-mode barcode scanner, 58/80 mm ESC/POS receipt printers, regular document printers, TSPL/ZPL label printers, cash drawers, and a second screen or tablet as a customer display.
