If you run a Pakistani retail business — clothing shop, pharmacy, restaurant, electronics store — you have probably been told you need to "integrate with FBR POS". Here is what that actually means, who is required to do it, and how to comply without buying expensive enterprise software.
What FBR POS integration actually is
The Federal Board of Revenue (FBR) introduced mandatory POS integration for Tier-1 retailers in Pakistan to verify sales-tax collection in real time. The idea is simple:
- Your POS prints a receipt with a structured FBR invoice number and a QR code.
- The customer (or FBR officer) scans the QR code to verify the receipt is real on the FBR Tax Asaan app or website.
- FBR cross-references the receipt against the sales-tax return you file. Discrepancies trigger an audit.
The result: tax evasion via under-reporting becomes very hard, and serious retailers get a verifiable proof-of-sale system.
Who is required to integrate?
FBR's Tier-1 retailer definition includes:
- Retailers with annual electricity bill above PKR 1,200,000.
- Retailers in air-conditioned shopping mall locations.
- Retailers operating chains with 2+ branches.
- Wholesalers with annual turnover above PKR 100M.
- Restaurants in Tier-1 cities above a turnover threshold (currently PKR 50M+).
Even if you are not technically Tier-1 today, FBR-formatted receipts are increasingly being treated as a quality signal by customers and corporate buyers. Most serious Pakistani retailers are voluntarily upgrading to FBR-formatted receipts in 2026.
What an FBR-compliant receipt must contain
Every receipt your POS prints must include:
- Your business name as registered with FBR.
- NTN (National Tax Number).
- STRN (Sales Tax Registration Number).
- POS Registration Number issued by FBR after integration.
- FBR Invoice Number in the standard format
STRN-DDMMYYHHMMSS-sequence. - Date and time of sale.
- Itemised breakdown with each product's name, quantity, unit price, and total.
- Sales tax breakdown showing the GST amount per item or in total.
- Total amount paid.
- QR code linking to the FBR verification URL with the FBR invoice number encoded.
The FBR Invoice Number format
This is the part most generic POS systems get wrong. The format is strictly:
STRN-DDMMYYHHMMSS-sequence
For example, if your STRN is 1234567, you sold something at 14:32:08 on 12 March 2026, and it is the 47th sale of the day:
1234567-1203261432080047
Generic POS software cannot generate this — it has to be hard-coded for the FBR format. WoBooks generates this automatically on every sale.
The QR code
The QR encodes a verification URL like:
https://e.fbr.gov.pk/verify?invoice=1234567-1203261432080047
Customers scan with the FBR Tax Asaan app or any QR scanner; they see whether the receipt was registered with FBR. This is a strong trust signal — fake receipts cannot be verified.
Real-time vs offline FBR transmission
FBR currently allows two modes:
- Real-time: every receipt is transmitted to the FBR Integration Endpoint (FIE) at the moment of sale. Required for highest-tier integrators.
- Offline / batch: receipts are stored locally and uploaded in batches (typically daily). Allowed for many retailers as a transition path.
WoBooks ships FBR-formatted receipts (NTN, STRN, FBR invoice number, QR) on every plan that includes the POS. Real-time FIE transmission is on the WoBooks roadmap. Until that ships, retailers can still print fully FBR-formatted receipts and submit returns via the FBR portal.
How WoBooks handles it
The WoBooks FBR POS integration page covers the full scope. The headline:
- Every receipt prints with NTN, STRN, FBR invoice number, and scannable QR.
- POS Registration Number is configurable per outlet.
- Built-in sales-tax engine handles per-item GST rates and produces a sales-tax report ready for your FBR return.
- Multi-branch chains can register each branch's POS separately.
- Real-time FIE transmission on roadmap; current customers have full FBR-formatted receipts today.
Practical setup checklist
- Confirm whether you are Tier-1 — check your electricity bill, location, and turnover.
- Register for STRN if you are not already (FBR Iris portal, free).
- Apply for POS Registration with FBR (one-time process per outlet).
- Configure your POS software with NTN, STRN, POS Reg Number — in WoBooks this is one screen in Settings.
- Test print a receipt and scan the QR with the FBR Tax Asaan app to verify.
- Train your counter staff to issue receipts on every sale — Tier-1 retailers can be fined for non-issuance.
