How to Connect Your ERP or Accounting Software to FBR Digital Invoicing (SAP, QuickBooks, Odoo, Tally)
You do not have to replace your accounting system to comply with FBR Digital Invoicing. Here are the three ways to connect an ERP or accounting package — SAP, Oracle, Dynamics, QuickBooks, Sage, Tally or Odoo — to FBR's DI API, and the trade-offs of each.
You keep your books where they are
FBR Digital Invoicing does not require a specific accounting package. What it requires is that each taxable sales invoice is posted to FBR's DI API and returns an Invoice Reference Number (IRN) and QR code. Any system that can send a compliant invoice payload — or hand its invoice data to something that can — satisfies that.
So the real task is a bridge between the software that already records your sales and FBR's API. There are three common ways to build that bridge, and the right one depends on your invoice volume and whether you have developers.
Option 1 — Direct API integration
A developer maps your ERP's invoice fields to the FBR DI v1.12 payload, handles the sandbox and production tokens, submits each invoice, and stores the returned IRN and QR code back against the record. SAP (SD/MM), Oracle, Microsoft Dynamics and larger ERPs usually go this route, sometimes through middleware such as SAP PI/PO or CPI.
It gives the tightest, most automated flow but is the most work: it needs development, testing against every sale type you use, and ongoing maintenance whenever FBR updates the specification. Timelines for complex ERP integrations are commonly reported in weeks to a few months.
Option 2 — A ready platform that already holds the integration
Instead of building the bridge yourself, you use a PRAL-certified platform that already speaks the FBR DI API. Your team enters or imports invoices, and the platform validates, posts and QR-stamps them. This removes the developer work, the token handling and the spec-maintenance burden.
This is the fastest path for most SMEs and mid-market businesses: signup to first compliant invoice can be same-day, because the hard integration already exists and is kept current with the specification.
Option 3 — File import (CSV/Excel) as a bridge
Where a direct API build is not justified, many teams export invoices from their accounting software as CSV or Excel and import them into an FBR-connected platform, which then posts them. QuickBooks, Sage, Tally and Odoo users often start here because the export already exists.
It is lower-effort than a full API build and keeps your books in place, at the cost of a batch step rather than instant per-invoice posting. It is a practical middle ground while a business decides whether a deeper integration is worth it.
Choosing the right route
Match the method to your volume and resources: a large enterprise with an in-house SAP or Oracle team may prefer a direct API integration; a growing business without developers usually gets compliant faster with a ready platform, optionally fed by CSV export from its existing books.
Digi Invoice is the ready-platform route: it validates every invoice against the FBR DI v1.12 rules, posts to sandbox or production, returns the IRN and QR code, and keeps a searchable ledger — so you can stay on QuickBooks, Tally, Odoo or a spreadsheet and still issue fully compliant FBR invoices without building or maintaining an API integration.
