Invoice Processing Platform (IPP) - Payment Amount does not Reflect Invoice Amount

The following outlines the process to obtain additional information if the invoice payment amount does not reflect the amount of the invoice.

Log into IPP at www.ipp.gov and select Collector (Supplier) module. Sign in using ID.me or Login.gov. The IPP Collector home page will display.

There are two valid reasons that could result in an invoice payment being a lesser amount than the original invoice submission:

  1. Discount was offered on the invoice.
  2. Offset was collected through the Treasury Offset Program.

Checking Payment Status

  • Select All under Payment Status from the home page to display your payments for the last 120 days.
