Hassle-Free Security Onboarding:
- ✓Complete management of your company's secure system keys and portal registrations.
- ✓Official URA compliance validation check performed on all digital tax receipt layouts.

Engineered for absolute tax automation
Automated Fiscalization
Each invoice or receipt goes to URA as it is raised, and comes back with its fiscal document number, verification code and QR code, ready to print.
Secure Connection to URA
Everything URA's EFRIS requires before it accepts a document — set up once for each taxpayer, then kept working for you.
E-Invoice Layout Formatting
Generates legal 6-section receipts containing monopaced verification keys, FD serial numbers, and URA-compliant scannable verification QR links.
Automatic TIN Validations
Validates purchaser TIN numbers in real time directly against official URA databases to secure tax credit allocations and avoid filing rejects.
Every Tax Type Covered
Standard, zero-rated, exempt and deemed VAT, excise duty and discounts are sent to URA as your system recorded them. When a document does not meet URA's rules, you are told what is wrong and what to do about it.
Credit Notes & Stock Control
Beyond sales invoices: file credit notes for refunds and returns, and keep URA's stock records accurate with increases, decreases and branch-to-branch transfers.
Plug-and-Play ERP Middleware Integration
Any ERP / POS — REST API
Our primary integration path: a single secure REST API (X-API-Key auth) any system can call. Register products, fiscalize invoices, file credit notes, and manage stock straight from your own software.
QuickBooks Online & Desktop
Our most complete connector. OAuth product and invoice sync for Online; local database sync via QB Web Connector for Desktop branches and legacy retail registers.
Zoho Books & Custom POS
Direct connection over our RESTful JSON endpoints — capture invoices on creation and trigger immediate EFRIS fiscalization from Zoho or any bespoke POS.
Xero — Beta
Xero connectivity is in active development. Talk to us to join the early-access rollout and shape the integration for your workflow.

Connecting your accounting system
The EFRIS side is the same whatever you run. What differs is how the invoice gets out of your system — so each has its own notes.
QuickBooks
Online and Desktop connect differently. Invoices fiscalised as they are raised, with the FDN and QR code returned for printing.
QuickBooks & EFRIS →Tally
TallyPrime and Tally.ERP 9, reached on your own network. The fiscal details go back onto the voucher and onto the printed invoice.
Tally & EFRIS →Sage
Pastel, Evolution, 300, X3 or Business Cloud. Which Sage you run decides the route, and it is the first thing to settle.
Sage & EFRIS →Odoo
Online, Odoo.sh or self-hosted. Where it is hosted decides whether a rejection can stop the invoice being posted.
Odoo & EFRIS →Zoho Books
Cloud, authorised once through Zoho. Nothing installed anywhere, and the QR code lands on the template you already use.
Zoho Books & EFRIS →Something else
A custom ERP, an in-house system or a POS nobody has heard of. If it can produce an invoice, it can be connected.

Alongside the integration work we do for clients, we build and maintain the software behind it. Both of these are ours.
