Filed as the sale is rung up
Not a monthly export. The invoice goes the moment the order completes, which is what the regulation actually requires.

Pakistan's national tax authority — POS invoice integration
Every sale is submitted to FBR's POS (IMS) gateway in the official invoice format using your own POS ID and token. The fiscal invoice number comes back in time to print on the customer's receipt as a QR code they can verify themselves in the Tax Asaan app.

What the FBR integration does
The QR code prints on the receipt
Scannable in Tax Asaan, so a diner can check the tax they paid was reported.
Real reasons when FBR rejects one
The order page shows the authority's own message — usually a PCT code or a rate that does not match your registration — rather than a generic error.
Per-branch registration
Each outlet has its own POS ID, which is how FBR issues them. A multi-branch account keeps them straight.
A default PCT code
Set once under Settings → Tax Integration so a new dish is never filed without one.
