TL;DR · WeSearch summary

The article provides a technical guide for developers integrating Pakistani business software with the FBR's Digital Invoicing API, mandated under SRO 709(I)/2025 for all sales-tax-registered entities. It outlines the steps to authenticate, construct compliant invoice payloads, and submit them via the PRAL API, including handling errors and preparing for production. The integration ensures real-time invoice transmission and receipt of an Invoice Reference Number (IRN) and QR code for customer invoices.

Key facts

▪All sales-tax-registered businesses in Pakistan must transmit invoices to the FBR in real time using the PRAL Digital Invoicing API under SRO 709(I)/2025.
▪Developers must obtain a bearer token via the FBR IRIS portal, construct a strictly formatted JSON invoice payload, and submit it to one of three key API endpoints.
▪The API returns an IRN and QR code that must be printed on customer invoices, and cancellations are only allowed within a 72-hour correction window after submission.
