If you've received a notice from FBR or you want to proactively comply with digital invoicing requirements, this complete step-by-step guide will walk you through the entire registration process — from IRIS portal setup to submitting your first invoice.
Prerequisites for FBR Digital Invoicing
Before starting, ensure you have:
- ✅ Active NTN (National Tax Number) registered with FBR
- ✅ Sales Tax Registration Number (STRN) — you must be registered for Sales Tax
- ✅ Access to FBR IRIS Portal (iris.fbr.gov.pk) with your login credentials
- ✅ Your business details: address, phone, email
- ✅ A computer with internet access
Step 1: Login to FBR IRIS Portal
- Visit iris.fbr.gov.pk
- Click on "Registration" on the left sidebar
- Enter your NTN and password
- Complete CAPTCHA verification
- Click "Login"
Step 2: Navigate to Digital Invoicing Section
- After login, go to Registration → Digital Invoicing
- You'll see the Digital Invoicing Registration Form
- Your company details will be pre-filled from your NTN registration
Step 3: Choose Your Licensed Integrator
FBR requires you to choose a Licensed Integrator (LI) — this is the authorized gateway between your software and FBR. Available options include:
- PRAL (Pakistan Revenue Automation Limited) — Government-backed, free of cost ✅ RECOMMENDED
- Haball — Private integrator
- EY Ford Rhodes — Private integrator
- WebDNA — Private integrator
We recommend choosing PRAL as your Licensed Integrator because it's free and backed by the government.
Step 4: Receive Your API Credentials
After registration approval, you'll receive:
- Client ID — Your unique identifier
- Client Secret — Your authentication key
Keep these credentials safe — you'll need them to configure your invoicing software.
Step 5: Choose Your Invoicing Software
You have two options:
Option A: Build Your Own Integration (Not Recommended)
Requires 3-6 months of development, ongoing maintenance, and deep API knowledge.
Option B: Use a Pre-Built Solution (Recommended) ✅
