EFRIS requires all in-scope businesses to issue e-invoices with a unique EFRIS receipt number and a QR code that links to URA's verification portal, replacing manual or paper-based invoicing.
The EFRIS system-to-system (S2S) API allows ERP and POS systems to generate, sign, and transmit e-invoices directly to URA without manual entry into the EFRIS web portal. Each B2B e-invoice must include the customer's TIN; B2C receipts can use a generic consumer TIN. Both sales invoices and credit notes are supported.
Advatech builds the EFRIS S2S API integration layer, handles URA sandbox testing, maps your invoice data to EFRIS schema requirements, and manages error handling and retry flows. We also support the transition from portal-based submission to full API automation.

Single-branch deployments with a modern ERP or POS typically complete in 7–10 business days after KYC sign-off.
Multi-branch rollouts or migrations from the EFRIS web portal to S2S API typically take 2–4 weeks, depending on system complexity, TIN validation setup, and sandbox access speed.

EFRIS (Electronic Fiscal Receipting and Invoicing System) is Uganda Revenue Authority's e-invoicing platform. It became mandatory for VAT-registered businesses under the Tax Procedures Code (Amendment) Act. URA has rolled out the requirement in phases, starting with large taxpayers, with ongoing expansion to medium and smaller VAT-registered businesses.
EFRIS supports sales invoices (for both B2B and B2C transactions), credit notes, and stock-in/stock-out records for inventory-tracking businesses. B2B invoices require the customer's TIN; B2C invoices can use a generic consumer TIN. Each invoice receives a unique EFRIS receipt number and a QR code.
The EFRIS web portal requires manual data entry for each invoice: practical for very low-volume businesses but not scalable for ERP or POS environments. The system-to-system (S2S) API allows your ERP or POS to generate and submit e-invoices programmatically without portal interaction. Advatech implements the S2S path for all but the smallest operators.
Yes. EFRIS requires the buyer's TIN on B2B e-invoices. This is a key difference from B2C transactions, which use a URA-assigned generic consumer TIN. During field mapping, Advatech sets up TIN lookup and validation so that B2B invoices include the correct customer TIN before submission to EFRIS.
Every e-invoice submitted to EFRIS receives a unique EFRIS receipt number assigned by URA. This number, along with a QR code, must appear on the printed or digital invoice issued to the customer. Scanning the QR code links to URA's EFRIS verification portal where the invoice details can be confirmed.
