What is user acceptance testing software?
User acceptance testing (UAT) software is any tool that helps the business users who will use a system confirm it does what they need before go-live. It assigns test scenarios to people, collects pass or fail results with evidence, logs defects and produces the record you need for sign-off. A spreadsheet can do this for a small project; a purpose-built tool pays off when many testers, many scenarios or an audit trail are involved.
TL;DR
- UAT testing is the last check before launch, run by the people who will use the system. It asks “does this work for our business?”, not “does the code work?”.
- Spreadsheets fail at UAT in predictable ways: no evidence, no version control, lost comments and no sign-off record. Four tool types replace them: test management tools, visual feedback tools, issue trackers and (for repeat releases) automation.
- No tool is best in general. In our weighted example, a test management tool wins for an ERP go-live where traceability and sign-off reporting carry the weight, and a visual feedback tool wins for a website redesign where tester ease and screenshots matter most.
- Tools do not fix a weak UAT plan. Written scenarios, entry and exit criteria, severity rules and a sign-off rule matter more than the product you pick.
- The worked examples (effort estimate, defect burn-down, weights) are illustrations built for this guide, not measured results.
- CommercePundit plans and runs UAT for ERP, CRM and custom software projects. See the last section.
UAT vs QA: how is user acceptance testing different?
| QA / system testing | User acceptance testing | |
|---|---|---|
| Who tests | Testers and developers | Business users and process owners |
| Question asked | Does it meet the specification? | Does it support how we actually work? |
| Typical test cases | Technical, edge cases, integrations, performance | Real business scenarios from start to finish |
| Environment | Test or staging with test data | A production-like environment with realistic data |
| Found defects | Bugs against the specification | Bugs plus gaps, wrong assumptions and missing steps |
| Outcome | Ready for UAT | Accepted, accepted with conditions or rejected |
The two overlap, and a system that fails QA should never reach UAT. If your QA step is thin, fix that first; our software testing services cover the layer before UAT.
Why do spreadsheets break down for UAT?
- No evidence. “Passed” in a cell proves nothing months later. Auditors and sponsors want screenshots, data used and who ran it.
- Version chaos. Six testers and six copies of the file means merging results by hand.
- Weak defect handling. A comment column is not a workflow with an owner, status and retest.
- No link to requirements. You cannot show that every requirement has at least one passed scenario.
- Poor reporting. Counting passed, failed and blocked by hand on the last day is how sign-off slips.
A spreadsheet still works for a small project with a few testers and a few dozen scenarios. The problems start when testers multiply or someone asks for proof.
What kinds of UAT testing tools exist?
| Type | How it helps | Examples (not a ranking) | Watch out for |
|---|---|---|---|
| Spreadsheet | Free and familiar; fine for very small projects | Excel, Google Sheets | Everything in the list above |
| Test management tools | Scenarios, assignments, results, requirement links and sign-off reports | TestRail, Zephyr, Xray | Setup time; testers who are not technical may find them heavy |
| Visual feedback and bug capture tools | Testers mark up the live page, and screenshots, browser details and notes go straight to your tracker | Usersnap, BugHerd, Marker.io | Strong for websites and web apps; weaker for scripted ERP scenarios |
| Issue trackers | Defects and tasks with workflow, already used by the delivery team | Jira, Azure DevOps, Linear | No built-in test scripts or sign-off view unless you add plugins |
| Test automation platforms | Repeat UAT-style checks every release | Testsigma, Tricentis Tosca, TestComplete | Automates what is already stable, not first-time acceptance |
| Analytics and session tools | Show where real users struggle after launch | Hotjar, FullStory, Amplitude | Observation tools, not UAT tools; useful for post-launch checks only |
Some lists of “UAT tools” mix in analytics and monitoring products. Those help after launch but do not manage acceptance testing, so judge a product by whether it assigns scenarios, records evidence and produces a sign-off record.
How do you choose UAT software? A weighted example
Score each tool type from 1 (poor) to 5 (strong) on the criteria that matter, then weight the criteria so they add to 100. The scores describe hypothetical tool types, not ratings of any product. What matters is how the weights change the answer.
| Criterion | Weight: ERP go-live | Weight: website redesign | Spreadsheet | Test management tool | Visual feedback tool | Issue tracker only |
|---|---|---|---|---|---|---|
| Ease for non-technical testers | 10 | 30 | 5 | 3 | 5 | 2 |
| Traceability to requirements | 30 | 5 | 1 | 5 | 2 | 4 |
| Evidence capture (screenshots, data) | 10 | 30 | 2 | 3 | 5 | 3 |
| Setup time | 10 | 15 | 5 | 3 | 4 | 4 |
| Cost | 10 | 10 | 5 | 3 | 3 | 4 |
| Sign-off reporting | 30 | 10 | 2 | 5 | 3 | 4 |
| Weighted score: ERP go-live | 2.60 | 4.20 | 3.20 | 3.70 | ||
| Weighted score: website redesign | 3.60 | 3.30 | 4.30 | 3.10 |
For the ERP go-live, the test management tool scores 4.20 and wins because traceability and sign-off reporting carry 60% of the weight. For the website redesign, the visual feedback tool scores 4.30 because tester ease and evidence capture carry 60%. A plain spreadsheet scores 3.60 in the redesign case, ahead of the test management tool at 3.30, which is a fair reminder that heavy tools can lose on small, visual projects. Agree the weights with the sponsor before you look at a single product.
How much effort does UAT take? A worked estimate
Suppose an ERP go-live has 40 business scenarios (for example “create a sales order, ship it, invoice it and receive payment”). A tester needs about 25 minutes per scenario on average, and about 30% of the effort is retesting after fixes. These inputs are assumptions; replace them with timings from a pilot run.
| Line | Calculation | Result |
|---|---|---|
| First-pass execution | 40 scenarios x 25 minutes | 16.7 hours |
| Retesting | 30% of first pass | 5.0 hours |
| Total test effort | 21.7 hours | |
| Per tester (6 testers) | Total divided by 6 | 3.6 hours each |
That is about 3.6 hours per tester, which sounds small. The real cost is calendar time: testers have day jobs, defects wait for fixes and data has to be reset between runs. Plan two weeks, book the testers’ time in advance and agree that UAT outranks their other work for those days.
What does a healthy defect burn-down look like?
Track only the defects that can block sign-off (severity 1 and 2) each day. The numbers below are an illustration of a project that finishes cleanly.
| UAT day | New severity 1 and 2 defects | Fixed and retested | Open at end of day |
|---|---|---|---|
| 1 | 5 | 0 | 5 |
| 2 | 5 | 3 | 7 |
| 3 | 3 | 5 | 5 |
| 4 | 2 | 4 | 3 |
| 5 | 2 | 3 | 2 |
| 6 | 1 | 2 | 1 |
| 7 | 1 | 1 | 1 |
| 8 | 0 | 1 | 0 |
Open blockers peak on day 2 at 7 and fall steadily. The pattern to look for is that new finds shrink while fixes keep pace. If new finds stay flat after day 4, the system is not ready or the scenarios are exposing a design gap, and extending the date is cheaper than launching. In this example the exit rule (no new blocker found in a day and none open) is first met on day 8.
How do you run UAT in six steps?
| Step | What happens | Entry criteria | Output |
|---|---|---|---|
| 1. Plan | Write the UAT test plan: scope, testers, environment, dates and sign-off rule | Requirements are approved | UAT test plan |
| 2. Write scenarios | Business users write end-to-end scenarios with expected results and test data | Plan approved | Scenario list tied to requirements |
| 3. Prepare the environment | Load realistic data, create user accounts with real permissions, freeze the build | QA is complete with no open blockers | Ready environment and a smoke test |
| 4. Execute | Testers run scenarios, record pass, fail or blocked, and capture evidence | Environment ready; testers trained | Results and defect log |
| 5. Triage and fix | Review defects daily, set severity, fix, retest | Defects logged with steps and evidence | Burn-down, retest results |
| 6. Sign off | Sponsor and process owners accept, accept with conditions or reject | Exit criteria met | Signed acceptance record |
What should a UAT scenario and severity rule contain?
| Field | Example |
|---|---|
| Scenario ID and name | UAT-014 Create a back-order and fulfill it when stock arrives |
| Linked requirement | REQ-032 Back-orders ship automatically on receipt |
| Tester and role | Warehouse supervisor |
| Preconditions and data | Item with zero stock, customer with credit approved |
| Steps | Numbered, in the language the tester uses at work |
| Expected result | Order moves to ready to ship when stock is received |
| Actual result and evidence | Pass or fail, plus a screenshot or recording |
| Defect link | Issue ID if it failed |
| Severity | Meaning | Typical sign-off rule (example) |
|---|---|---|
| 1 Critical | Blocks a core process or corrupts data; no workaround | None open |
| 2 High | Major function broken but a workaround exists | Few open, each with an owner, workaround and fix date |
| 3 Medium | Minor function or usability problem | Logged for a later release |
| 4 Low | Cosmetic or wording | Logged |
The thresholds are examples; set yours with the sponsor before testing starts so nobody negotiates under deadline pressure. The same idea applies to ERP, CRM and custom builds. Our guides to ERP implementation, CRM and ERP integration and ecommerce ERP integration show where UAT sits in a full project, and ERP system examples helps you write realistic scenarios by industry. For Odoo projects, see our Odoo development company guide.
When should UAT scenarios become automated tests?
The first time a scenario runs, a person should run it. Once it passes and the process is stable, the scenario is a candidate for automation so that later releases get the same check without a week of business time. Automate the scenarios that are repeated, stable and high value. Our automation testing services turn accepted UAT scenarios into suites that run on every release, and our overview of top software testing companies helps you compare partners.
What mistakes ruin UAT?
| Mistake | What happens | Fix |
|---|---|---|
| Testers are chosen by availability, not knowledge | Real workflows go untested | Pick people who do the work every day and free their time |
| Test data is unrealistic | Everything passes, then production data breaks it | Use masked production-like data |
| No exit criteria | Go-live is decided by the calendar | Write the sign-off rule before testing begins |
| Requirements change during UAT | Nobody knows what “done” means | Freeze scope; route new requests to a later release |
| UAT starts before QA is done | Testers waste time on bugs QA should catch | Require a QA exit report as the entry criterion |
| Sign-off by email only | No record of what was tested or accepted | Keep results, evidence and the acceptance statement together |
Early products have the same need in smaller form: see our guide to MVP development for how founders can run a lightweight acceptance round.
Frequently Asked Questions
What is UAT software?
UAT software helps business users test a system before go-live. It assigns scenarios, records pass or fail results with evidence, logs defects and produces a sign-off record. It can be a test management tool, a visual feedback tool or a configured issue tracker.
Do I need special software for UAT?
Not always. A small project with a few testers can use a well-structured spreadsheet. Dedicated software pays off with many testers, many scenarios, regulated environments or a need for audit evidence.
What is the difference between UAT and QA?
QA checks the system against its specification and is run by testers. UAT checks that the system supports real business work and is run by the people who will use it. QA should finish before UAT starts.
How do you do UAT?
Plan scope and sign-off rules, write business scenarios, prepare a production-like environment, execute and record results with evidence, triage and retest defects daily, then sign off against the exit criteria.
Which tools are used for UAT?
Teams use test management tools such as TestRail, Zephyr or Xray, visual feedback tools such as Usersnap or BugHerd, issue trackers such as Jira, and spreadsheets for small projects. The right choice depends on the project type and the weight you put on traceability and ease of use.
Who should perform UAT?
Business users and process owners who do the work every day, plus a project lead to coordinate. Developers and QA support them but should not be the main testers.
How long does UAT take?
It depends on the number of scenarios and testers. A useful method is to multiply scenarios by minutes per scenario, add 30% for retesting and then plan for calendar time, because testers have other work and fixes take time. Many projects allow about two weeks.
What are UAT entry and exit criteria?
Entry criteria say when UAT may start, such as QA complete, realistic data loaded and testers trained. Exit criteria say when it may end, such as no open critical defects and agreed limits on high-severity ones. Write both before testing begins.
Can UAT be automated?
Partly. The first run of a scenario should be manual. Once a scenario is stable and repeated each release, automating it saves business time. Automation does not replace the first acceptance by real users.
Bottom Line
User acceptance testing software is worth the effort when you need proof, not just opinions. Choose the tool type by what carries the weight in your project, write scenarios and exit criteria before testing, track blocker defects daily and sign off against a rule agreed in advance.
