As a system approaches completion, the client needs to check more than the visual appearance. Problems that are invisible in a simple screen review can appear after operations begin.
Use a workflow close to real work and confirm that registration, updates, review, output, and notification behave as expected.
Test the complete business workflow

Do not only touch each feature separately. Start at the beginning of a real case and follow it through to completion.
For an application workflow, for example, test registration, review, status change, sharing with the owner, and confirmation in the list as one sequence.
- Can a case move from registration to completion?
- Can a user go back and correct it?
- Can the necessary information be found in a list or search?
- Can the field user operate without guessing?
Check permissions and the shape of the data

Confirm what each role can view and edit. Test not only as an administrator but also as a normal user and a read-only user.
Use realistic data, including long names, blank values, past dates, and a larger number of records, to see whether the screens and rules remain usable.
- The information visible for each permission level
- Fields that should not be editable
- Long text and blank values
- History that should remain available
Test exceptions and error states too

Try missing input, duplicate data, insufficient permissions, and a failed network request. The user should understand what to correct when something does not work.
Summary
- Acceptance testing checks whether real work can proceed
- Test workflows rather than isolated features only
- Check visibility and editing by permission
- Use realistic data
- Test exceptions and errors
