Centralized Account Processing System (CAPS)

CAPS is…
The Centralized Account Processing System which is an alternative to presenting checks and cash for postage and paying annual fees at multiple postal locations. CAPS is an electronic postage payment system that provides business mailers a centralized, convenient, and cost-effective way to allow business mailers to electronically (e.g. ACH Debit, ACH Credit and Fed wires) pay for:

Permit Imprint
Business Reply Mai (BRM)*
Merchandise Return Service (MRS)*
Postage Due Account*
USPS Corporate Account™
Address Element Correction

*Limited availability. Check with your local Post office to determine availability in your area.

Customers can choose from the following CAPS account types:

Centralized Trust Accounts — Customers deposit funds using electronic funds transfer (i.e. ACH Credit or Fed wire) to the USPS’s bank prior to mailing. The CAPS account is automatically updated with your deposit and then reduced when local post offices process postage statements.

Centralized Debit Account —Customers designate a debit-enabled bank account for postage charges. The bank account is debited for the total day's postage on the next bank business day.

For International Mailings
Deferred Debit (International Postage Payment) – Establish deferred debiting for international products, such as International Surface Airlift and International Priority Airmail. This isn’t a separate account type__ it’s an extension of an existing debit account. International postage payments debit the designated mailer’s bank account on the 5th and 20th of each month. Customs payments are not deferred.
