ProShip® is one of the first software shipping engines in the country to be Manifest Analysis and Certification (MAC™) Cycle P Certified from the United States Post Office (USPS). This certification highlights ProShip’s commitment to offer the best carrier compliant, multi-carrier shipping software to its customers.

The MAC™ Certification reinforces ProShip’s pledge to comply with the latest industry requirements. At ProShip, we believe by taking care of these basic fundamentals, our customers will be able to focus on their daily operations. MAC™ was developed by the United States Postal Service in cooperation with the mailing industry, to evaluate manifesting software. The process is available only to software manufacturers who actually develop manifest software either for retail or for internal use. MAC™ tests the ability of the manifest software to produce accurate postage and fees as well as quality documentation.

This certification provides a common platform to measure the quality of manifest products and determines their accuracy in accordance with requirements set forth in the Domestic Mail Manual (DMM). The purpose of MAC™ is to improve the accuracy of manifested mailings, thereby improving the flow of your shipments.
