What I like most about Oversight is how it strengthens our audit process with smarter, more consistent detection of potential policy issues, duplicate charges, missing documentation, and unusual spending patterns. It gives our team clearer visibility into expense activity and helps us concentrate on the transactions that truly need review, instead of relying solely on manual sampling. I also appreciate that Oversight supports both compliance and the employee experience by surfacing issues earlier and giving us a chance to correct them or coach employees before small problems become bigger ones. Overall, it helps us move toward a more proactive, data-driven T&E audit program. Review collected by and hosted on G2.com.

What I like least about Oversight is that, like any audit analytics tool, it requires thoughtful configuration and ongoing tuning to make sure alerts are meaningful and aligned to T-Mobile policy. Some items may be flagged even though they are ultimately allowable, so there will still be a need for human review, context, and judgment. There is also some upfront effort required to build the right workflows, templates, exception handling, and user guidance. That said, those challenges feel manageable and are outweighed by the long-term benefits of stronger visibility, consistency, and compliance. Review collected by and hosted on G2.com.
