Xero EFRIS Integration in Uganda: URA API Compliance Case Study

What Is EFRIS in Uganda?

EFRIS stands for Electronic Fiscal Receipting and Invoicing Solution. It is a Uganda Revenue Authority system used to record business transactions and share transaction information with URA.

When a transaction is submitted through EFRIS, the system processes the information and generates fiscal details that can include a Fiscal Document Number, verification code and QR code.

EFRIS is currently mandatory for all VAT-registered businesses and businesses operating in designated economic sectors, whether VAT registered or not. URA expanded the requirement to additional designated sectors effective July 1, 2025.

Businesses using computerized accounting systems such as Xero can use a system-to-system connection to communicate with EFRIS through an API rather than entering the same transaction information manually into multiple systems.

URA specifically identifies system-to-system API integration as an option for organizations using computerized accounting systems and processing higher transaction volumes.

What Is an EFRIS Invoice?

An EFRIS invoice is an electronic fiscal document generated through the Uganda Revenue Authority’s EFRIS system.

According to URA, an e-invoice is issued through EFRIS by a taxpayer registered for VAT, while a non-VAT-registered taxpayer using EFRIS issues an e-receipt.

A fiscal document typically contains several identifying elements.

When an invoice is generated in an accounting system such as Xero, a system-to-system integration can submit the relevant transaction data to EFRIS.

EFRIS processes the transaction and returns the required fiscal information to the invoicing workflow.

URA confirms that Fiscal Document Numbers, verification codes and QR codes are key features of EFRIS e-invoices and e-receipts

The Client

The client operates an accounting and bookkeeping agency in Kampala, Uganda, managing accounting activities for approximately 40 businesses through Xero.

Following the introduction of EFRIS requirements, the agency needed a reliable way to help its clients issue fiscalized invoices and maintain compliance with Uganda Revenue Authority invoicing policies.

Manually transferring invoice and customer information between Xero and EFRIS would have required considerable administrative effort and increased the risk of data-entry errors. The client, therefore, approached Satva Solutions to develop middleware that could connect Xero with EFRIS and manage the exchange of transaction data.

Xero EFRIS Integration Challenges

The client needed to manage EFRIS compliance across approximately 40 businesses without duplicating accounting work between Xero and the URA system.

The primary challenges included:

• Migrating and configuring existing customer, product, and transaction data for EFRIS.
• Submitting approved Xero invoices to EFRIS for fiscalization.
• Keeping customer, inventory, invoice, credit note, debit note, purchase order, and bill records synchronized.
• Capturing the customer’s Taxpayer Identification Number before submitting eligible invoices.
• Returning the Fiscal Document Number, verification code, and QR code to the invoice workflow.
• Maintaining transaction logs for audit reviews and troubleshooting.
• Correcting invoice errors through credit notes because fiscalized invoices cannot simply be deleted.

URA identifies credit notes as the appropriate document for cancelling or amending an earlier invoice when errors occur.

Xero–EFRIS Integration Solution

Satva Solutions designed and developed middleware connecting Xero with EFRIS through a system-to-system API integration.

Our team worked with the client and relevant URA stakeholders to understand the required hosting, security, transaction, and invoicing requirements. Based on these requirements, we created an integration architecture that controlled how data moved between Xero, the middleware, and EFRIS.

The solution included the following capabilities:

• Master and Transaction Data Synchronization: Customer, product, inventory, invoice, credit note, debit note, purchase order, and bill data could be transferred from Xero to EFRIS without repeated manual entry.
• TIN-Based Customer Validation: The integration used the Taxpayer Identification Number stored in Xero to retrieve and validate taxpayer details before invoice submission.
• Approval-Based Invoice Submission: Only invoices approved in Xero were sent to EFRIS, reducing the likelihood of incomplete or unapproved transactions being fiscalized.
• EFRIS Fiscalization Response: After processing an invoice, EFRIS returned the Fiscal Document Number, verification code, and QR code required on the fiscal document.
• Invoice Delivery: The completed EFRIS invoice could be emailed to the customer with the required fiscal information.
• Synchronization Logs: Every integration transaction was recorded in the middleware to support audit tracking, error investigation, and troubleshooting.

What Data Was Synchronized Between Xero and EFRIS?

The integration was designed around the accounting and transaction information needed by the client’s workflow.

The exact data mapping for an EFRIS integration can vary according to the accounting system, transaction structure and compliance requirements.

The Solution

How the Xero–EFRIS Integration Works

1. An invoice is created and approved in Xero.
2. The middleware checks the invoice and customer information, including the customer TIN.
3. Eligible invoice data is submitted to EFRIS through the API.
4. EFRIS validates and fiscalizes the transaction.
5. The Fiscal Document Number, verification code, and QR code are returned.
6. The fiscalized invoice is stored in the workflow and sent to the customer.
7. The middleware records the synchronization status for audit and troubleshooting purposes.

Results and Business Outcomes

The Xero–EFRIS integration gave the accounting agency a centralized way to manage fiscal invoicing for its clients while continuing to use Xero as the primary accounting platform.

Following implementation:

• Transaction data no longer had to be manually re-entered into EFRIS.
• Approved Xero invoices could be submitted for fiscalization through the middleware.
• Required fiscal information was returned and included in customer invoices.
• TIN-based customer retrieval reduced errors caused by manually entering taxpayer information.
• Synchronization logs improved visibility into successful and failed transactions.
• The agency could offer EFRIS integration and compliance support as an additional service to its clients.
• Clients could continue focusing on their operations while the accounting agency managed their fiscal invoicing workflow.

Key Outcomes

• Manual duplication of invoice data between Xero and EFRIS was eliminated for integrated transactions.
• Customer and invoice-entry errors were reduced through TIN-based retrieval and validation.
• Fiscal Document Numbers, verification codes, and QR codes were incorporated into the invoice workflow.
• Approved invoices could be fiscalized through a controlled system-to-system process.
• The accounting agency gained an additional service offering for its client base.

Who Should Consider Xero EFRIS Integration?

A custom Xero EFRIS integration can be relevant when a business already manages accounting and invoicing in Xero but also needs transaction information processed through EFRIS.

It is particularly relevant for accounting firms managing multiple organizations, businesses processing larger invoice volumes, organizations that want Xero to remain their primary accounting environment, and teams currently duplicating transaction information between systems.

URA identifies system-to-system API connectivity as an EFRIS option for businesses with computerized accounting systems and higher transaction volumes.

Businesses using accounting or ERP platforms other than Xero can also evaluate a similar API-based architecture where the relevant systems and EFRIS requirements support it.

Conclusion

By connecting Xero with EFRIS, Satva Solutions helped the accounting agency reduce duplicate invoice processing and manage URA fiscal invoicing requirements for approximately 40 clients.

The middleware enabled approved Xero invoices to be submitted to EFRIS, fiscalized, and returned with the required Fiscal Document Number, verification code, and QR code.

It also provided transaction logs and TIN-based customer validation to support more reliable invoice processing.

Businesses using Xero, QuickBooks, Sage, SAP Business One, Odoo, Tally, Oracle, or another accounting platform can use a similar system-to-system integration approach to connect their invoicing workflows with EFRIS.
