Implementing Microsoft Dynamics 365 Business Central is a transformative step for any organisation. It promises streamlined operations, real-time insights, and a unified platform for finance, supply chain, and customer management. But one critical phase often gets overlooked or rushed: User Acceptance Testing (UAT).

And when UAT is skipped or poorly executed, the consequences can be severe, ranging from operational disruptions to a complete loss of user confidence.

What Is UAT and Why Does It Matter?

User Acceptance Testing is the final checkpoint before go-live. It’s where real users validate that the system meets their business needs - not just technically, but practically. It’s not just about testing the software; it’s about testing the people, the processes, and the readiness of the organisation.

In Business Central implementations, UAT ensures:

- The configured workflows match real-world operations.

- Permissions and roles are correctly assigned.

- Staff are confident using the system.

- Data migration has preserved integrity.

 - Integrations with external systems (e.g., EDI, warehouse platforms) function as expected.

The Pitfalls of Skipping UAT

Skipping or minimising UAT can lead to:

1. Operational Chaos at Go-Live: Without UAT, users may encounter unexpected errors, missing data, or broken workflows.

2. Loss of User Confidence: If users feel unprepared or blindsided by system behaviour, their trust in the platform erodes.

3. Increased Support Costs: Unresolved bugs and misconfigurations post-launch often require urgent fixes.

4. Missed Business Requirements: UAT is the last chance to catch gaps between business needs and system capabilities.

5. Delayed ROI: Without UAT, the system may not deliver the expected efficiencies.

Building Confidence Through UAT

UAT isn’t just a technical exercise - it’s a confidence-building process. It gives users hands-on experience, validates training, and ensures that the system is ready for real world use.

Recommendations

- Start Early: Don’t wait until the last minute.

- Use Real Scenarios: Test actual business processes.

- Assign Accountability: Make sure every department knows its role.

- Provide Support: Offer training and assign support buddies.

- Document Everything: Use structured feedback forms and issue tracking.

- Ask erp365 for their assistance using their PIC methodology for UAT excellence

Conclusion

Skipping UAT is like launching a ship without checking for leaks. It might float - for a while - but the risk of sinking is real. By investing in thorough User Acceptance Testing, organisations not only validate their Business Central setup but also empower their teams, reduce risk, and set the stage for a successful go-live. Let UAT be your confidence builder - not your blind spot.
