Keep your sales running smoothly even during internet outages, while staying compliant with Phase 2 of the e-Invoicing regulations issued by ZATCA (Zakat, Tax and Customs Authority).
HOW IT WORKS
Offline mode is activated automatically when the internet disconnects during a sale.
The cashier can issue up to 300 receipts while offline. A notice appears next to the total amount to indicate a temporary receipt is being issued instead of an invoice.
Once the internet connection is restored, Rewaa automatically converts all temporary receipts into simplified tax invoices, fully compliant with ZATCA regulations.
IMPORTANT GUIDELINES
Offline selling works only on the POS screen. Do not exit the register during disconnection.
This is a temporary solution — reconnect to the internet as soon as possible.
TEMPORARY RECEIPT & QR CODE
The temporary receipt includes a QR code the customer can scan with their phone camera:
If the tax invoice is ready, it opens immediately.
If still processing, a message will appear: “Your invoice is being processed, please try again later.”
CLOSING THE REGISTER
If there are any receipts not yet converted to simplified tax invoices, an alert will appear showing the number of pending invoices. The cashier won’t be able to close the register until all documents are synced and converted successfully.
OFFLINE MODE LIMITATIONS
B2B (taxable) invoices cannot be issued offline, per ZATCA regulations. The system will block these and show a message explaining why. A red cloud icon will appear next to any customer with a registered commercial number or VAT ID during offline mode.
The following features are not supported offline:
Creating quotes
Adding new customers
Postpaid payments
Rewaa Pay
Product price updates made by other users.
Real-time inventory updates — available quantities may not reflect accurately.
