How to View and Manage Payments in the Payment Overview

Payment Overview is your central hub for managing a payment in Mastt. From here, you can review payment amounts, verify compliance with AI, manage supporting documents, and track payment history, all in one place.

Before you start

A payment must already exist within a contract before you can view Payment Overview.
