This Accounts Payable (API) module in our MIP Fund Accounting training covers the full AP transaction cycle, from entering invoices to handling the corrections that inevitably come up. AP work tends to be high volume and deadline-driven, so the value here is learning a consistent workflow that keeps vendor history, expense coding, and reporting clean.

You will start with invoice entry and check processing inside the Accounts Payable module. The training walks through session setup, invoice numbering practices, 1099 coding when it applies, and expense line coding so invoices post to the right accounts. It also covers how to run unposted transaction reports and post sessions, which is the main checkpoint for catching mistakes before they become part of the permanent transaction record.

After entry, the course moves into payment processing. You will learn how to select invoices for payment, generate system checks, and complete posting after checks are printed so payments are reflected correctly in AP and cash. This includes the steps that tend to cause confusion in real workflows, such as understanding what has been selected, what has been printed, and what is not fully posted yet.

The module also covers how to void checks properly, including where the void options live, how to choose a void date, and what changes the system makes when a check is voided. Getting voids right matters because the timing and method affects both vendor balances and the cash side of reporting. Finally, you will learn how to reverse or correct transactions when something is already posted. The training covers how to identify the relevant session IDs, reverse posted invoices, re-enter corrected information, and verify that the updates are reflected through reports before posting again. This is the difference between a quick, traceable fix and a correction that creates more questions than it answers later.
