Many companies will have multiple PO and Caller Boxes that are difficult to renew and manage especially having to interface with local Post Offices.  Mailers can now manage (open, close, view, pay fees, and renew) all PO Boxes, Caller, and Reserve Services for multiple locations from a single application and receive electronic notifications for renewals. With an ePOBOL and EPS accounts, commercial mailers can now pay for PO Box services with an ACH Debit payment account.
