HayyaTax: FTA Approved Accounting and Tax Consultancy in Dubai
Structured testing of your e-invoicing setup before go-live, so issues are caught while they're still easy to fix.
User Acceptance Testing validates that your configured e-invoicing setup correctly generates, sends, and receives invoices exactly as intended, before you rely on it for real transactions.
Businesses that have completed e-invoicing implementation and need structured testing before relying on the system for live transactions.
UAT should be completed after implementation and before your business starts relying on e-invoicing for real transactions — testing after go-live means issues affect real invoices.
A thorough UAT covers these three areas before sign-off.
We design test scenarios covering your real transaction types.
We run the tests, log any issues, and track them to resolution.
We confirm your setup is genuinely ready before you go live.
We follow up after go-live to confirm real transactions are processing correctly.
HayyaTax is an FTA-approved Tax Agent — the same team running your UAT also manages your wider VAT and Corporate Tax compliance.

Authorized to represent clients directly with the Federal Tax Authority.
