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.
% At A Glance
Tests real transaction scenarios end-to-end
Confirms data accuracy across invoice types
Catches issues before go-live, not after
Who Needs This
If implementation is done, testing comes next.
Businesses that have completed e-invoicing implementation and need structured testing before relying on the system for live transactions.
Timing
Test before, not after, go-live.
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.
What You'll Need
Documents for UAT.
Finalized implementation and configuration details
Test transaction scenarios covering your transaction types
Sign-off criteria or checklist, if already defined
Why This Matters
What's at risk without proper testing.
Skipping structured testing risks errors on real invoices once live
Issues found after go-live are harder and more disruptive to fix
A clear sign-off process avoids going live on an unverified assumption

Common questions
Frequently asked questions on e-invoicing UAT.
What is UAT for e-invoicing? ⌄
It's structured testing of your fully configured e-invoicing setup, confirming it generates, sends, and receives invoices correctly before you rely on it for live transactions.
Who should be involved in testing? ⌄
Typically your finance/accounting team alongside whoever manages the relevant systems — we coordinate the testing process with the right people.
What happens if issues are found? ⌄
We log every issue, track it to resolution, and re-test before sign-off — that's the point of doing this before go-live, not after.
Is this required before go-live? ⌄
It's strongly recommended — going live without structured testing means any issues are found on real transactions instead.
How does this follow on from implementation? ⌄
UAT is the step right after implementation, confirming everything configured actually works as intended.
