USPS Replaced CAPS with EPS

One of the most important USPS innovations was the Centralized Account Payment System (CAPS). Prior to CAPS, most mailers had to pay for postage via check into trust accounts associated with each local mailing permit they established, and in advance of mailings. The CAPS system allowed for customers to cover all of their payments to USPS through one centralized account funded with electronic funds transfers.

The most advanced feature of CAPS was enabling mailers to have their own bank accounts debited by the USPS with the Automated Clearinghouse (ACH), after the mail was entered. This enabled “just in time payment” that brought USPS customer service more in line with the business world. It also reduced costs on both the customer and USPS sides, as it replaced thousands of paper checks with ACH transfers.

Today the USPS has given CAPS a makeover, (now known as Enterprise Payment System (EPS)). EPS will keep the core enhancements of CAPS that are now taken for granted and add more functionality and ease of use, according to a recent Postal announcement.

As of April 1, 2019, the USPS will retire CAPS.  After launching the new EPS payment processing system which supports multiple payment options, including mobile check deposit, offers more reporting features, and allows management of multiple USPS business functions under one account.
