FBR Digital Invoicing 2026: Deadlines, Penalties and How to Integrate
Every sales tax registered business in Pakistan must now issue invoices through FBR. Here are the deadlines, the Rs 500,000+ penalties, PRAL vs licensed integrators and the 72-hour rule.

If you're registered for sales tax in Pakistan, every invoice you issue now has to go through FBR's system before it reaches your customer. No FBR invoice number, no valid invoice. And without a valid invoice, your buyer can't claim input tax, which is usually the moment a business finds out it has a problem: a customer calls and says they won't pay until the invoice is fixed.
FBR wanted every liable business live by 31 July 2026. That date has passed, penalties have been enforced since January, and by FBR's own figures only about a third of registered taxpayers were issuing live digital invoices at the end of March. So a lot of businesses are still catching up.
We build POS, inventory and ERP software for Pakistani businesses, and FBR integration has been the most common request on our desk this year. This guide covers what the rules say, who they apply to, what it costs and how the integration actually works. We've linked our sources at the end.
What is FBR digital invoicing?
FBR digital invoicing is the system where a sales tax registered person's invoicing software sends each invoice to FBR in real time, and FBR sends back a unique invoice number and a verifiable QR code that must be printed on the invoice. It's set out in Chapter XIV of the Sales Tax Rules 2006, which was rewritten by S.R.O. 69(I)/2025 in January 2025.
The key point is the order of events. FBR checks and numbers the invoice first, then you issue it. An invoice you made in Excel and uploaded later isn't the same thing.
Who has to use FBR digital invoicing?
Every person registered for sales tax with FBR. That includes:
Public and private limited companies, including single member companies
Partnerships, AOPs and sole proprietors with an active STRN
All importers, whatever their size
Manufacturers, wholesalers, distributors and retailers
E-commerce sellers and exporters who make local taxable supplies
Tier-1 retailers were already reporting sales through POS integration, and they are covered too.
Businesses registered only with a provincial authority (PRA, SRB, KPRA) for services aren't covered by this federal system. FBR has also published a draft, S.R.O. 288(I)/2026, that would bring restaurants, clinics, salons, schools and professional services under a similar regime through the income tax rules. It wasn't final at the time of writing, but it's a sign of where this is going.
What were the deadlines?
The phased schedule in S.R.O. 1852(I)/2025, issued on 24 September 2025, was:
Who | Go-live date |
|---|---|
Public companies, all importers, and businesses with turnover above Rs 1 billion | 1 November 2025 |
Individuals and AOPs with turnover above Rs 100 million | 1 November 2025 |
Companies with turnover from Rs 100 million to Rs 1 billion | 15 November 2025 |
Companies with turnover up to Rs 100 million | 1 December 2025 |
All other registered persons | 31 December 2025 |
Adoption was slow, so FBR set 31 July 2026 as the date by which it expected everyone to be live. If you're reading this and still not integrated, every one of these dates has passed, and the job now is to get compliant as fast as you safely can.
What are the penalties for not integrating?
Under section 33 of the Sales Tax Act 1990, the penalty for failing to integrate is reported as a ladder:
Default | Penalty |
|---|---|
First | Rs 500,000 |
Second | Rs 1,000,000 |
Third | Rs 2,000,000 |
Fourth and after | Rs 3,000,000 |
Continued default can lead to the premises being sealed. Separately, issuing an invoice outside the system is reported to carry a fine of Rs 50,000 or 2 percent of the tax involved, whichever is higher. The Finance Act 2026 also gave FBR power to blacklist or de-register businesses that don't comply.
The fines get the headlines, but the commercial hit usually comes first. Your registered customers need your FBR invoice number to claim input tax. If your invoices don't have one, big buyers will start holding payments or moving to suppliers who are compliant. Tier-1 retailers that aren't integrated also have their input tax reduced under section 8B(6).
FBR is also staffing up for this. It had recruited 431 new auditors by March 2026 and estimates the scheme could bring in an extra Rs 46 billion in 2026-27.
What has to be on an FBR digital invoice?
Your software has to send, and print, details for the seller, the buyer and each line item:
Seller name, address, NTN and STRN, plus invoice serial number and date
Buyer name and address, and their STRN if registered (NTN or CNIC if not), with their registration type
For each item: description, HS code, quantity, unit of measure, value excluding tax, sales tax rate and amount, any further tax, extra tax, FED or withholding, discounts, and the value including tax
FBR then returns three things you can't make yourself: the unique FBR invoice number (around 22 characters), a QR code that can be verified, and the FBR Digital Invoicing logo.
A warning we keep repeating to clients: printing a QR code on a manual invoice doesn't make it compliant. The QR code has to come from a real FBR invoice number. A QR code that only looks right is misrepresentation, which is worse than not having one at all.
Credit notes and debit notes go through the same system. That matters for returns and price changes, because your buyer's input tax adjustment depends on FBR seeing the note.
How do you integrate with FBR: PRAL or a licensed integrator?
There are two routes.
Direct integration with PRAL (Pakistan Revenue Automation Limited, FBR's IT company) is free. Your own developers connect your software to FBR's digital invoicing API. It makes sense if you have an in-house team and a system you control, but you carry all the technical work and any future API changes.
A licensed integrator is a company approved by FBR to make that connection for you. They charge a configuration fee, which FBR caps, and they handle the API connection and support. For most small and mid-sized businesses this is the faster option. Since STGO No. 01 of 2026, you're allowed to use more than one licensed integrator, which helps if you run separate systems for different branches or channels. FBR keeps the official list of approved integrators.
FBR itself doesn't charge a fee for integration under either route.
What are the steps to go live?
Check that your STRN is active and your business profile in IRIS is up to date. Integration fails quietly when the profile is wrong.
Register on FBR's digital invoicing portal.
Check whether your current software can send structured invoice data (JSON), store the FBR invoice number against each invoice, and queue invoices if the internet goes down.
Choose PRAL or a licensed integrator.
Test in the sandbox, then get your production token and go live.
Step 3 is where most of the time goes. A well-built ERP can be integrated in roughly two weeks. A heavily customised older system can take three months, or turn out to be cheaper to replace.
What should you test in the sandbox?
Don't stop at one clean invoice. The cases that break in the first month are the ones nobody tested:
Standard-rated, zero-rated and exempt supplies
Third schedule items, where tax is on retail price
Sales with withholding
Sales to unregistered buyers, where further tax applies
Credit notes for returns and debit notes for price increases
Wrong HS codes and units of measure cause a lot of rejections too. Clean up your item master before testing, not during it.
Can you cancel or edit an FBR invoice?
Only within 72 hours, and only for a genuine mistake. STGO No. 01 of 2026 allows a valid electronic invoice to be cancelled, deleted or edited through FBR's system within 72 hours of being generated. After that you need approval from the Commissioner Inland Revenue, which in practice means you shouldn't count on it.
For normal business changes after the 72 hours (a customer returns goods, a price is revised) use a credit note or debit note. Those are for commercial adjustments. The 72-hour window is for fixing errors.
This changes how your team should work. If someone reviews invoices once a week, mistakes will sit past the 72-hour limit. Daily checks are safer.
What does FBR integration cost?
FBR charges nothing. Your costs come from:
Upgrading or replacing your invoicing software, usually the biggest cost
The integrator's configuration fee, if you use one
Custom development, if you run your own ERP
POS hardware for outlets that need it
Staff training
An ongoing subscription, which some integrators charge per invoice and others per month
The deciding factor is the software you already have. If it was built properly, integration is a modest job. If it's a patched-together system with invoices partly in Excel, you'll spend more, and it's often the right time to move to something that handles inventory and accounts properly too.
Common mistakes we see
Thinking a QR code alone means compliance.
Testing only one kind of sale and finding out about further tax and third schedule items in production.
No offline queue, so invoices can't be issued when the internet drops at a shop or warehouse.
Storing the FBR invoice number nowhere, so it can't be reprinted or matched later.
Wrong or missing HS codes in the item master.
Correcting invoices after 72 hours instead of using credit notes.
Sales staff still writing manual bills at a branch "just for today".
Key takeaways
Every sales tax registered person must issue invoices through FBR's system and print the FBR invoice number and QR code.
All deadlines under S.R.O. 1852(I)/2025 have passed, and FBR's target for full adoption was 31 July 2026.
Penalties for not integrating are reported to start at Rs 500,000 and rise to Rs 3 million, with sealing for continued default.
You can integrate directly with PRAL for free or use one or more licensed integrators.
Invoices can only be corrected within 72 hours. After that, use credit or debit notes.
Your buyers' input tax claims depend on your FBR invoice number, so non-compliance costs you customers as well as fines.
Frequently asked questions
Is FBR digital invoicing mandatory for all businesses?
It's mandatory for every person registered for sales tax with FBR. Businesses registered only with provincial revenue authorities for services aren't covered by this system, though a draft income tax rule may extend invoicing requirements to many service businesses.
What is the penalty for not integrating with FBR digital invoicing?
Reported penalties under section 33 of the Sales Tax Act start at Rs 500,000 for the first default, then Rs 1 million, Rs 2 million and Rs 3 million for later defaults. Continued default can lead to sealing of premises.
Is PRAL integration free?
Yes. FBR doesn't charge for direct integration through PRAL. You pay for your own development work, or for a licensed integrator if you choose one.
Can I use Excel for FBR digital invoicing?
Not on its own. Each invoice has to be sent to FBR through integrated software and receive an FBR invoice number before it's issued. Some integrators offer a web portal where you can type invoices in, which works for low volumes.
How long does FBR integration take?
Around two weeks for a well-built system with a capable integrator. Older, heavily customised software can take up to three months, or need replacing.
Can I cancel an FBR digital invoice?
Yes, within 72 hours of generating it and only for a genuine mistake, under STGO No. 01 of 2026. After 72 hours you need the Commissioner's approval, so use a credit note for later changes.
Do I need FBR digital invoicing if I already have Tier-1 POS integration?
Tier-1 retailers are covered by digital invoicing as registered persons. Check with your POS provider or integrator that your setup issues compliant invoices for all your sales, including any sales to registered businesses.
Need your software connected to FBR?
We build POS, inventory and ERP systems for businesses across Pakistan, with FBR digital invoicing built in, and we also connect existing systems to FBR. If your software can't produce FBR invoice numbers yet, send us your setup on WhatsApp and we'll come back with a written scope and a fixed quote. If you sell in the Gulf too, our guide to UAE e-invoicing covers the rules there. If invoices still live in spreadsheets, read signs your business has outgrown Excel.
This is a practical guide, not tax advice. FBR updates rules often, so confirm your position on fbr.gov.pk or with your tax adviser.
