UAT meaning: Six essentials for testing a new finance system
UAT means user acceptance testing: intended users check whether a system meets agreed business requirements. An invoice might save without error yet reach the wrong approver. The software has performed an action, but the business process has failed.
For a finance team introducing a new system, UAT provides evidence for deciding whether the setup is ready for everyday work.
1. Define the outcomes users need
Start with an observable result. “The system produces reports” leaves too much open to interpretation. A clearer requirement is that a department manager sees the correct invoice totals for their department, with access restricted to that department’s figures.
A team researching sage intacct alternatives can document its approval rules and reporting needs during software selection, then carry those requirements forward into UAT.
These checkable conditions are acceptance criteria. Prioritise workflows where failure could interrupt operations, misstate information or weaken controls. Technical testing and business acceptance provide complementary evidence: one checks technical behaviour, while the other assesses suitability for the intended work.
2. Give each role a part in testing
An accounts payable clerk understands how invoices arrive, which details are often missing and what happens when an approver is unavailable. Approving managers bring a different perspective: the information needed to make a decision.
Include people representing the main user roles, testing with the permissions they will actually have. Testing everything through an administrator account risks overlooking restrictions that apply to ordinary users. Give testers enough training to perform their tasks and protected time to complete them.
Technical staff can prepare the environment and investigate problems. Agree who owns each process and who has authority to accept the results. Management approval should rest on users’ evidence.
3. Prepare early, then check readiness
Gather requirements and draft scenarios before implementation is complete. Begin testing once the configuration is sufficiently stable, representative permissions and usable test data are available, and known blocking technical problems have been addressed.
UAT often informs the go-live decision. Teams can also test completed workflows in stages, repeating affected tests after changes.
Use a controlled environment that reflects the intended setup, including relevant integrations. Synthetic or appropriately protected data should represent the transactions users handle. Confirm that testing is isolated from live payments and unintended outbound messages.
Supplier demonstrations show possibilities and training teaches users how to work; UAT checks agreed criteria through recorded results.
4. Test both permitted and blocked actions
A scenario describes a business task. A test case specifies the user role, actions and expected result.
Consider an illustrative £1,200 supplier invoice that requires authorised approval before becoming eligible for payment. The accounts payable clerk can enter it but has no approval authority.
Test the permitted route first. The clerk enters and submits the invoice; the authorised manager reviews and approves it. Check that it reaches the correct manager, remains ineligible for payment until approval, and then changes to the expected status. The approval record should identify the manager.
Next, use the clerk’s account to attempt approval. The expected result is refusal, leaving the invoice unapproved and ineligible for payment.
The successful route alone would leave a significant control gap untested. Add relevant exceptions, such as rejection and resubmission, where they form part of the agreed workflow. Set each expected outcome before execution.
5. Make failures reproducible, then retest
Connect every result to its requirement. Record the test identifier, user role, steps, expected and actual results, pass or fail status, and supporting evidence. Include the environment or configuration version so reviewers can interpret the outcome later.
Suppose the clerk’s approval attempt succeeds. Describe the failure precisely: the system allowed approval by a role without authority, and the invoice’s status changed. Attach the relevant screenshot or audit record and assign the issue for investigation.
Prioritise defects by business impact, rather than simply how easy they are to reproduce. After correction, repeat the failed test and check the authorised route too. The fix must preserve the manager’s ability to approve while blocking the clerk’s attempt.
Keep the original failure, correction and retest evidence together, with a clear resolution.
6. Sign off against the evidence
Agree acceptance conditions before execution. The business owner should assess coverage, results and unresolved issues against those conditions, rather than treating the launch date as a reason to approve.
Some outstanding issues can be accepted; others justify delaying release. Document their impact, any workable interim measures, the responsible owner and the explicit decision. An unresolved approval-control failure deserves different treatment from a cosmetic layout issue.
Sign-off should identify the tested scope and supporting evidence. Security and regulatory compliance require their own checks alongside business acceptance.
Completed test records show what happened. A sound acceptance decision explains why those results are sufficient for the intended use.
