Does it pay invoices?

No. It flags and holds items. Your team still approves and releases payments.

Which accounting systems can it connect to?

We scope this per client. Many systems offer exports or APIs we can read from.

How do you handle false alarms?

Reviewers mark results as correct or not, and the matching rules are tuned from that feedback.
