Custom and older systems connected through PRAL or your licensed integrator.

Start your project

Connect Your ERP, POS or Billing Software to FBR Digital Invoicing

FBR digital invoicing is mandatory for sales-tax registered businesses, but ready-made plug-ins only cover popular ERPs. In-house software, older POS systems and spreadsheet billing are left to handle the API, data mapping and failures alone.

Your existing system sends every invoice to FBR in real time through a licensed integrator, prints the FBR invoice number and QR code, and handles errors and outages without losing a sale.

Typical timeline: 1-4 Weeks.

Frequently asked questions

Who has to use FBR digital invoicing?
FBR states that electronic invoicing is mandatory for corporate and non-corporate sales-tax registered persons, and that digital invoices are required for the sales reported in Annexure-C of the sales tax return. Check the latest SROs with your tax adviser for your category.
Is Nexariza AI a licensed FBR integrator?
No. FBR requires integration through a licensed integrator: PRAL, which integrates free of cost on demand, or a private licensed integrator. We build and maintain the connection between your own software and that integrator: data mapping, invoice printing, error handling and testing.
Do we have to replace our ERP or POS?
Usually not. If your software can send data over the internet, we add a connector to it. Popular ERPs such as Odoo and ERPNext have ready plug-ins; we help when your system is custom, older or spreadsheet-based, or when you need several branches and systems connected.
What happens if the internet or the FBR system is down?
FBR expects the Sales Tax Act and Rules to be followed in every situation. We build a queue that stores invoices safely, marks them, and submits them as soon as the connection returns, with alerts so nothing is missed.
What is the penalty for not integrating?
FBR’s guidance says businesses that do not integrate by the deadline are liable to penal action under section 33 of the Sales Tax Act, 1990. Confirm the current amounts with your tax adviser.
How long does it take?
A connector for one system typically takes one to four weeks, including data mapping, sandbox testing with the integrator and go-live. Several branches or systems take longer.
