Mercantile Processing Inc. (MPI) was built on a foundation of merchant services but over the years we have created programs that allow partners to adopt products or services that are not merchant based. These programs include gateway or POS only products to be promoted outside merchant ISO's. MPI has been servicing Bank Partner relationships for close to 15 years. We are your fully integrated payments solution offering a best-in-class white-labeled white glove personal approach. We are compatible with 3,000 merchant softwares and have an award-winning 24/7 US-based support staff.
