FBR Digital Invoicing & POS Systems
for Businesses in Karachi

Compliance is now enforced in Sindh
If you run a shop, restaurant, hotel, or wholesale business in Karachi, two tax authorities now expect your sales system to report electronically — and both began actively enforcing in 2026.
- FBR penalty enforcement began in January 2026. The digital invoicing rollout completed its phased schedule between November and December 2025, and paper invoices for notified supplies are no longer legally valid. Every qualifying invoice must be transmitted in real time and carry a verified Invoice Reference Number (IRN) and QR code.
- The Sindh Revenue Board has intensified monitoring. SRB inspection teams have been visiting Karachi restaurants and service outlets to check POS integration, directing service businesses to run fully functional, integrated POS systems — with warnings of legal action for non-compliance.
- SRB's electronic invoice monitoring regime (under the Sindh Sales Tax on Services Act 2011) requires registered service providers' invoicing software to connect with SRB's platform in real time, backed by inspections, possible video monitoring, and customer invoice-verification incentives.
- Non-integration is expensive on the FBR side. Under Finance Bill 2026, failure to integrate carries a penalty of up to Rs 1 million, rising to up to Rs 5 million if the default continues beyond a month — with the possibility of premises being sealed.
Regulatory figures change frequently — verify the current position with FBR/SRB or a qualified tax advisor before acting.
FBR vs SRB: which one applies to you?
This is the question we hear most from Sindh businesses. The short answer: FBR is federal and covers goods; SRB is provincial and covers services. Here is how that plays out in practice.
FBR (Federal Board of Revenue)
FBR administers sales tax on goods — retailers, wholesalers, manufacturers and importers. Qualifying sales-tax-registered businesses must use FBR digital invoicing: every invoice is transmitted in real time through PRAL, FBR's licensed integrator, and returned with an IRN and QR code that make it legally valid. Buyers cannot claim input tax without a verified IRN.
- POS integration required for Tier-1 retailers — now defined by a Rs 200 million turnover test under Finance Bill 2026.
- Receipts must show the FBR invoice number, QR code and logo.
- Customers can verify receipts on the Tax Asaan app.
SRB (Sindh Revenue Board)
SRB administers Sindh Sales Tax on Services under the SSTS Act 2011, from its headquarters in Karachi. It covers restaurants, salons, hotels, marriage halls, couriers and other service providers across Sindh, and runs its own POS and invoice-monitoring integration regime for the sector.
- Sales systems connect to SRB in real time.
- Invoices carry a QR/barcode verifiable through SRB's invoice verification system.
- Current rules add real-time e-invoice monitoring and inspections.

Is FBR digital invoicing mandatory in Sindh?
FBR digital invoicing is a federal requirement, so it applies to qualifying sales-tax-registered businesses in Sindh just as in the rest of Pakistan. The phased rollout ran from November to December 2025 by turnover bracket, and penalty enforcement began in January 2026. If your business is notified, invoices must be transmitted to FBR in real time to remain legally valid.
What is the difference between FBR and SRB?
FBR is the federal tax authority and administers sales tax on goods, including digital invoicing and POS integration for retailers, wholesalers, manufacturers and importers. SRB, the Sindh Revenue Board, is provincial and administers Sindh Sales Tax on Services, covering restaurants, salons, hotels and other service providers. Many Karachi businesses fall under both, and each sales stream must report to the correct authority.
Do restaurants in Karachi need SRB POS integration?
Yes. Restaurants are among the service providers SRB targets for POS and invoice-monitoring integration under the Sindh Sales Tax on Services Act 2011. SRB inspection teams visit Karachi restaurants during monitoring drives and direct them to run fully functional, integrated POS systems. ZenTech configures restaurant POS systems to meet SRB's integration and invoice-format requirements.
What is the penalty for not integrating with FBR?
Under Finance Bill 2026, the penalty for failing to integrate can reach Rs 1 million, rising to as much as Rs 5 million if the default continues beyond one month, with the possibility of business premises being sealed. Regulatory figures change frequently — verify the current position with FBR or a qualified tax advisor before acting.
How much does an FBR-integrated POS system cost in Pakistan?
The cost depends on your business type, the number of terminals, hardware requirements, and how much customization your invoicing workflow needs. PRAL itself integrates free of cost — what you pay for is the software, hardware, configuration and support. Contact ZenTech on WhatsApp or by phone for a quote tailored to your Karachi or Sindh business.
Can I verify my invoice with SRB or the FBR Tax Asaan app?
Yes. FBR-integrated receipts carry a fiscal invoice number and QR code that customers can verify through FBR's Tax Asaan app, while SRB-integrated invoices carry a QR or barcode verifiable through SRB's invoice verification system. ZenTech configures your invoicing and POS so every receipt prints the correct verification details for the relevant authority.
