Frequently Asked Questions
What is SRB integration?
SRB integration connects your POS system directly to the Sindh Revenue Board’s computerized system (the Sales Data Controller) for automatic, real-time reporting of your sales. Each invoice gets an SRB fiscal invoice number and QR code that customers can verify, keeping your business compliant with Sindh sales tax rules.
Who needs SRB POS integration in Sindh?
SRB POS integration is mandatory for service businesses in Sindh, primarily in the hospitality, health, and beauty sectors — including restaurants, hotels, salons, and similar businesses providing taxable services.
How do I register for SRB POS integration?
You register your business branches and POS stations through the SRB POS portal using your Sindh National Tax Number (SNTN). After verification, SRB provides login access, and your POS is then connected to the SRB Sales Data Controller (SDC).
Does SRB integration cost anything from SRB?
The SRB POS system itself is provided by the Sindh Revenue Board at no cost. You only pay for the POS software and integration setup that connects your billing system to SRB. Switcher Techno can complete this integration for you.
How are SRB invoices verified?
Every SRB-integrated invoice includes a fiscal invoice number and a QR code. Customers can scan the QR code or use the eSRB (SRB Tax) mobile app to verify the invoice directly with the Sindh Revenue Board.
How long does SRB integration take?
Switcher Techno typically completes SRB integration with your existing POS system within 2-3 hours remotely, after which you can start issuing SRB-compliant invoices with fiscal numbers and QR codes.
