eIMS POS & Sales Software Integration - PRA / FBR Pakistan

Custom eIMS POS and Sales Software Integration in Pakistan

Khawaja Engineering customizes existing POS, ERP, restaurant, retail and sales software for supported electronic invoicing workflows in Pakistan. The service can connect invoice data with Punjab Revenue Authority (PRA) eIMS fiscalization and prepare eligible business systems for a separately scoped FBR digital invoicing integration.

New launch offer: competitive introductory implementation pricing is available for eligible new projects. The final quotation depends on the existing software, number of branches and POS terminals, invoice workflow, hosting environment, testing requirements and authority scope.

What Can Be Customized

• Connection with an existing POS, ERP, restaurant, retail or sales application.
• Invoice header and item mapping, including buyer details, tax, discounts, payment modes and returns.
• PRA POS registration and sandbox or production workflow assistance based on customer-provided credentials.
• Fiscal invoice response handling and receipt customization for the returned invoice number and QR code.
• Cloud, web, Windows and client-server deployment assessment.
• Multi-branch and multi-terminal configuration, logs, validation messages, retry handling and integration testing.
• FBR digital invoicing readiness assessment and API data mapping as a separate project scope.

How the PRA eIMS Workflow Operates

According to the official PRA technical specification, a registered POS sends invoice data to the supported fiscal device or integration endpoint. A successful record returns a fiscal invoice number for the customer receipt, where the POS can print the invoice number and QR code. Registration, sandbox testing, production access and current PRA requirements remain the responsibility of the taxpayer and relevant authority.

Designed for Existing Business Software

This is not limited to one fixed POS package. Khawaja Engineering first reviews the current database, programming technology, invoice format, branch structure and receipt design, then proposes a compatible integration layer. This makes the service suitable for businesses that want to retain their current sales workflow instead of replacing the complete application.

Typical Implementation Plan

1. Technical assessment: review the existing POS or sales software, invoice model, terminals and hosting environment.
2. Data mapping: map the required invoice and item fields, tax values, payment modes, returns and customer information.
3. Sandbox testing: validate payloads, responses, fiscal invoice numbers, error handling and receipt output.
4. Production preparation: support the approved registration, credentials, IP or terminal configuration supplied by the customer.
5. Go-live support: monitor initial transactions and document the agreed operating and support process.

Important PRA and FBR Compliance Note

PRA eIMS and FBR digital invoicing are separate authority systems. FBR states that notified registered persons may be required to integrate through a valid licensed integrator. Any FBR production configuration, registration or licensed-integrator activity is subject to current FBR rules and confirmation before work begins. Khawaja Engineering provides customized software and integration support and does not claim affiliation with, endorsement by or ownership of PRA, FBR or PRAL systems.

Service Coverage

Remote assessment and software integration inquiries are available across Pakistan, including Lahore, Rawalpindi, Islamabad, Faisalabad, Multan, Gujranwala, Sialkot, Karachi and other business locations. On-site requirements are confirmed according to project location and scope.

Frequently Asked Questions

What is PRA eIMS POS integration?

It connects registered POS or sales software with the PRA fiscal device or supported API workflow so invoice data can be fiscalized and a fiscal invoice number can be returned for the customer receipt.

Can my existing POS or sales software be connected?

In many cases, yes. Compatibility is confirmed after checking the programming technology, database, invoice fields, receipt format, deployment model and access available for customization.

Can the receipt include the fiscal invoice number and QR code?

Yes. The receipt layout can be customized to print the fiscal invoice number and QR code returned through the approved PRA workflow.

Is PRA eIMS the same as FBR digital invoicing?

No. They are separate systems with different onboarding, technical and compliance requirements. PRA and FBR work is assessed and quoted separately.

What information is needed for a quotation?

Share the software name and technology, number of branches and POS terminals, sample invoice, current receipt, required authority integration, hosting method and the contact details of your technical representative.
