FBR-formatted POS receipts for Pakistan businesses
NTN, STRN, FBR invoice number, and scannable FBR QR code — printed on every thermal receipt and A4 invoice, with one-time setup.
WoBooks stores your NTN, STRN, tax office, and POS registration number, assigns every sale an FBR-format invoice number (STRN-DDMMYYHHMMSS-seq), and prints a scannable FBR QR code containing the full invoice payload on both thermal and A4 receipts. Real-time transmission to the FBR Integration Endpoint is on our roadmap — today WoBooks produces the compliant document your accountant or Tier-1 integrator submits.

How to configure FBR POS receipts in WoBooks
One-time setup. Every order prints compliant after that.
Open store settings
From your WoBooks dashboard, go to Store Manager → Settings → Store → FBR Tax Compliance.
Enter your FBR credentials
Fill in your NTN (National Tax Number), STRN (Sales Tax Registration Number), RTO/LTO tax office, and POS registration number as issued by FBR.
Enable FBR invoice formatting
Toggle on "FBR Invoice Format" and optionally "Tax Breakdown on Receipts". Save.
Print a test receipt
Create a test order. The thermal and A4 layouts now show your NTN, STRN, FBR invoice number, and FBR-verify QR code.
Every order prints compliant
From that point on, every order — online, POS, or imported — renders the FBR-formatted receipt automatically.
Frequently asked questions
Straight answers about what WoBooks does and does not do for FBR.
Does WoBooks integrate with FBR POS?
WoBooks generates FBR-formatted receipts and invoices: it stores your NTN, STRN, tax office, and POS registration number, assigns each sale an FBR invoice number in the standard STRN-DDMMYYHHMMSS-sequence format, and prints a scannable FBR QR code on thermal and A4 invoices. WoBooks does not transmit invoices to FBR — it prepares the FBR-format document, and any submission to FBR is done separately by you, your accountant or your Tier-1 integrator.
What FBR information does WoBooks print on the receipt?
The thermal receipt and A4 PDF both print: your business NTN, STRN, RTO/LTO tax office, POS registration number, an FBR-format invoice number, the order date and time, item totals, tax breakdown, and a QR code labelled "FBR Verify" that encodes NTN, STRN, POS ID, invoice number, date, total, and tax as JSON.
Does WoBooks transmit invoices to the FBR server in real-time?
No. WoBooks produces the FBR-format document but does not push invoices to the FBR Integration Endpoint. Merchants use the WoBooks-generated FBR invoice numbers and QR codes as their system of record and submit to FBR through their existing Tier-1 integrator or accountant.
Where do I enter my NTN and STRN in WoBooks?
Go to Store Manager → Settings → Store → FBR Tax Compliance. You enter your NTN, STRN, tax office, and POS registration number, then toggle "FBR Invoice Format". Every receipt from that point prints the full FBR-formatted layout automatically.
What does the FBR invoice number look like in WoBooks?
WoBooks generates FBR invoice numbers in the format STRN-DDMMYYHHMMSS-sequence — combining your Sales Tax Registration Number, the transaction timestamp, and your order number. This format is assigned automatically on every order when FBR invoice is enabled; no manual numbering required.
Is the FBR QR code on WoBooks receipts really scannable?
Yes. The QR code on thermal and A4 receipts encodes a JSON payload containing NTN, STRN, POS ID, FBR invoice number, date, total, and tax total. It scans with any QR reader.
Do I need a Tier-1 retailer license to use WoBooks POS in Pakistan?
No — WoBooks is used by businesses of all sizes, not only Tier-1 retailers. Registered businesses with NTN/STRN can enable FBR invoice formatting so their receipts meet FBR document standards. Whether you are legally required to integrate with FBR real-time depends on your FBR classification; consult your tax advisor. WoBooks runs fine either way — receipt formatting is optional per-store.
How much does FBR-ready POS cost on WoBooks?
FBR receipt formatting is a setting in your WoBooks store, with no separate FBR add-on. The in-person POS is included from the Growth plan ($35/month). Every new store starts with a free 7-day trial.
