FBR Digital Invoicing Integration

The middleware is a thin server-side layer between whatever raises the invoice and the tax servers.

Server-side only. The terminal never calls the tax endpoint itself. Credentials stay on the server and are never exposed to the till or the browser.

Source-agnostic. ERPNext, a POS or an accounting package — the bridge takes the invoice from wherever it is raised and maps it onto the fields the tax API expects.

Validated before submission. Required fields, tax rates and buyer details are checked locally first, so a preventable rejection never reaches the wire.

A record per invoice. What was sent and what came back is stored against the invoice — which is what you need when a filing is questioned months later.

No manual export. Nothing is exported to a spreadsheet and re-keyed at the end of the day.

Compliance that slows the counter down does not survive contact with a busy shop.

Straight onto the receipt. The Invoice Reference Number and the dynamic QR come back and are written onto the document and the print format, then rendered on the thermal receipt.

Fast enough to be invisible. Submission and response happen inside the print cycle, so the queue at the till never notices it happened.

No hand-copying. Nobody transcribes a reference number from one screen onto another.

Failures are visible. A rejected submission is flagged with the reason it failed rather than silently retried, so the counter knows immediately.

The connection will drop. The shop still has to sell.

Keep printing. Invoices buffer to a durable local queue and receipts keep printing while the link is down.

Ordered replay. When the connection returns the queue drains in order, rather than all at once.

Replay cannot double-file. Each queued invoice carries its own key, so a replay after a partial failure cannot file the same invoice twice.

Visible depth. The dashboard shows what is still queued and what has filed, so nobody has to guess whether the shop is behind.
