FBR digital invoicing software for Pakistani businesses

Whether you are moving from manual IRIS entry or integrating sales tax invoices into daily operations, the platform supports sandbox testing and production submission, reusable buyer NTN profiles, HS code and UOM helpers, and plain-language guidance when FBR returns an error.

FBR digital invoicing under SRO 709

Under SRO 709(I)/2025 and the Sales Tax Act 1990, sales-tax-registered businesses in Pakistan must send their sales tax invoices to FBR electronically, in real time. That applies to corporate and non-corporate registered persons alike, which is why so many finance teams are moving off manual entry and onto integrated digital invoicing.

IRIS and PRAL integration, handled for you

Invoices reach FBR through the Digital Invoicing API operated by PRAL, using a Bearer token you generate for your NTN in the IRIS portal. Complete IRIS digital invoicing setup (including the integrator route FBR requires — often PRAL in IRIS). Then connect that token in software so you do not have to build or maintain your own API client. FBR digital invoicing integration details →

IRN, USIN and verifiable QR codes

Every accepted invoice comes back with an IRN (Invoice Registration Number), a USIN, and a QR code your buyer can scan to verify it. All three are printed on the branded invoice PDFs automatically, so what you hand a customer is already compliant.

Test in sandbox, then go live

Work through the FBR invoice scenarios that apply to your business in the sandbox environment, confirm each returns a valid response, then switch to your production token when you are ready. Finance teams use Integron Technologies — FBR Digital Invoicing to reduce rework, keep invoice data consistent, and submit with more confidence. Start with a free trial, connect your FBR token, and validate your first invoice in minutes.
