Bakery & Retail POS with Automatic FBR E-Invoicing

Built for a bakery client who needed both a real till and FBR tax compliance without running two disconnected systems. Staff ring up a sale on the SmartPOS desktop till exactly as normal — items, quantities, discounts — and the moment they save the bill, a fully compliant FBR Digital Invoicing (DI API) request fires automatically in the background through the PRAL gateway, with no extra step for the cashier to remember.

The invoicing side generates the strict DI-API-compliant JSON PRAL expects (built from the official allowlist, not an approximation), submits or validates it against the sandbox, and prints an IRN and QR code on the receipt the same way a government-approved invoice should look. Every request and response is logged for audit, invoices lock after submission so they can't be quietly edited afterward, and the integration runs in mock mode for demos or live mode once a business has its own PRAL bearer token. The result: a bakery or retail shop gets one till that's already tax-compliant on day one, instead of bolting FBR reporting on as an afterthought.
