This FBR integration guide covers POS and ERP teams connecting billing to digital invoicing in Pakistan — without duplicating every invoice in IRIS by hand.
Step 1 — IRIS and integrator route
Complete digital invoicing registration in IRIS, obtain sandbox and production tokens, and follow the licensed integrator pathway FBR requires for your taxpayer category (often PRAL selection in IRIS). Register digital invoice steps.
Step 2 — Choose integration style
- Manual/batch — export from ERP, create invoices in GetFBR dashboard
- API — POST invoice JSON, validate, submit, receive webhooks with IRN
- Hybrid — batch import during migration, API for go-live
Step 3 — Sandbox scenarios
Test each scenario your POS/ERP emits. Document field mappings (buyer NTN, HS, UOM, tax rates).
Step 4 — Production cutover
Switch token, monitor first live submits, and store PDFs with QR for audit. See FBR ERP integration and FBR POS integration.
