FBR Integration Services: Digital Invoicing & POS Integration in Pakistan
Bizloom ERP connects your ERP, POS or invoicing software to FBR’s digital invoicing system, so every sales tax invoice is reported in real time with a valid FBR invoice number and QR code. We handle the full process, from IRIS setup and sandbox scenario testing to go-live, error fixing and ongoing monitoring, for retailers, wholesalers, distributors, manufacturers and service businesses across Pakistan.
Built for retail, wholesale and service businesses transmitting sales invoice data as part of FBR's digital invoicing initiatives.
What is FBR integration?
FBR integration refers to connecting a business's point of sale, ERP or invoicing system directly to the Federal Board of Revenue's digital invoicing infrastructure, so sales invoice data is transmitted electronically as transactions happen.
Depending on the applicable FBR initiative and your sector, this can involve real-time invoice transmission from POS terminals, or structured digital invoicing from an ERP/accounting system, each with its own data and connectivity requirements.
FBR's requirements, applicable sectors and technical specifications are set by FBR and can change. This page describes how the integration is typically built; businesses should confirm current obligations against FBR's latest official notifications.
Who needs FBR integration?
- Retail businesses required to integrate POS systems with FBR
- Businesses issuing sales tax invoices that fall under FBR's digital invoicing requirements
- Multi-branch retail or restaurant chains needing standardized invoice transmission across locations
- Wholesalers and distributors invoicing through an ERP that isn't currently connected to FBR
- Businesses that have received a notice or fall under a category required to integrate
Which FBR Integration Does Your Business Need?
Pakistan has more than one integration requirement, and many businesses need more than one. We help you work out which applies to you.
| Requirement | Who it applies to | Authority |

| Digital invoicing | Sales-tax-registered businesses issuing sales tax invoices | FBR |
| POS integration | Tier-1 retailers and notified retail outlets | FBR |
| Restaurant and service POS | Restaurants and service businesses in Punjab and Sindh | PRA / SRB |

Connecting your ERP or POS to FBR
The moving parts behind FBR integration, explained without the technical detail.
Sales invoice integration
Each sales invoice generated in your system is structured into the data format FBR requires, capturing the details it needs to recognize the transaction.
FBR API / digital invoicing connectivity
Your ERP or POS connects to the relevant FBR API or digital invoicing channel using the required authentication and endpoint configuration.
Invoice data transmission
Invoice data is transmitted to FBR at the point of sale or on a defined schedule, depending on which digital invoicing pathway applies to your business.
Invoice number & reference handling
Invoice and reference numbers returned by FBR are captured and linked back to the original invoice record in your system for traceability.
POS and ERP integration
Integration is configured for point-of-sale terminals, back-office ERP/accounting systems, or both, depending on how your business issues invoices.
Validation & response handling
Responses from FBR, whether an acceptance, a reference number, or a rejection, are captured and matched back to the relevant invoice automatically.
Error handling & troubleshooting
Failed or rejected transmissions are flagged with the reason, so they can be corrected and resent instead of silently failing.
Testing before production
Invoice creation, transmission, and error scenarios are tested in the applicable test environment before the integration goes live.
Monitoring & ongoing support
After go-live, transmission health is monitored and the integration is maintained as requirements or endpoints change.

From Sandbox Testing to Go-Live
Before you can issue live invoices, FBR requires your system to pass the sandbox scenarios assigned to your business in IRIS. This is where many integrations get stuck. We handle it for you:
Learn more in our FBR sandbox scenario testing guide.
- Set up your digital invoicing details, business nature and sector in IRIS
- Configure sandbox credentials and IP whitelisting
- Map HS codes, units, sale types, rates and SROs for your items
- Pass every assigned scenario
- Generate your production token and go live
- Monitor submissions and fix rejections
Already Integrated But Invoices Are Getting Rejected?
Many businesses go live and then face daily rejections: HS code mismatches (error 0052), invalid buyer NTNs, wrong rates, province errors or failed credit notes. We diagnose the cause and fix it at the source, in your item and customer data, so the same errors don't come back.
Send us your error message on WhatsApp and we'll tell you what's causing it.
- Fix recurring FBR rejections
- Clean HS codes, units, sale types and buyer data
- Set up logging, alerts and automatic retries
- Handle cancellations and corrections within FBR’s 72-hour window
What You'll Need to Get Started
Don't have everything? We'll help you prepare during the assessment.
- Active sales tax registration and IRIS access
- Your NTN and business details
- A list of the products or services you sell
- Access to your ERP or POS system (or details of your vendor)
- A static IP address for your server, if self-hosted
How Much Does FBR Integration Cost?
FBR doesn't charge for integration itself. Your cost depends on your system, number of branches, data cleanup needed and ongoing support. We give you a fixed, itemized quote after a free assessment.

Questions businesses ask about FBR Integration.
It depends on how your business issues invoices. We assess whether your POS, your ERP/accounting system, or both need to connect to FBR, and configure the integration accordingly.
Rejected transmissions are flagged with the reason so your team can correct and resend the invoice. We also review recurring rejection patterns to reduce them going forward.
Yes. The integration is built to be deployed consistently across multiple branches, POS terminals or outlets.
Yes. Invoice creation, transmission, validation and error scenarios are tested in the applicable test environment before production go-live.
No integration can guarantee permanent compliance, since FBR updates its requirements over time. We build against current published requirements and provide monitoring and support to help you keep pace with changes; final compliance responsibility rests with the business.
Transmission uses the authentication and connectivity method required by the relevant FBR channel. Exact security configuration is confirmed during the technical assessment for your setup.
For sales-tax-registered businesses issuing sales tax invoices, FBR digital invoicing applies, and Tier-1 retailers must integrate their POS. Under the Finance Act 2026, FBR can suspend the sales tax registration of businesses that aren't integrated.
No. FBR doesn't charge for integration. Costs come from software, setup and support. Tier-1 retail invoices carry a Re 1 POS service fee collected from customers.
Yes. We regularly diagnose and fix rejections in existing integrations, including data issues in items, customers and tax setup.
Yes. We set up IRIS details, configure the sandbox, pass your assigned scenarios and generate your production token.
Yes. Restaurants in Punjab and Sindh report to provincial authorities, and we can set up integrated POS for PRA and SRB as well as FBR.
