Confirming E-Invoicing Works After Go-Live

Post-implementation review of UAE e-Invoicing controls and performance

Going live is not the end of the project. The first weeks and months often reveal issues that were not visible during testing: incomplete data, rejected transactions, manual workarounds, unclear responsibilities or reconciliation differences.

A post-implementation review helps management confirm that the e-Invoicing process is operating as designed and that key controls are working.

Focus on recurring issues

One-off implementation problems are expected. The bigger concern is a recurring issue that becomes part of the normal process without being formally resolved.

Our review focuses on patterns, root causes and control improvements rather than only checking whether the system is technically online.

Where issues relate to process design, refer to Process & Workflow Design.
