Allegiance Merchant Services

About

Allegiance Merchant Services – Company Overview Founded to serve the unique payment processing needs of high-volume, B2B industries, Allegiance Merchant Services has built its reputation on delivering secure, cost-effective solutions tailored to complex billing environments — particularly in the building supply and construction materials sectors. Over the years, Allegiance has become a trusted partner by helping clients reduce risk and improve profitability. A cornerstone of its strategy has been fraud prevention through payer authentication tools, including advanced 3D Secure 2.0 protocols. These technologies authenticate the cardholder in real time, dramatically reducing chargebacks and unauthorized transactions — especially in card-not-present environments. At the same time, Allegiance has helped clients improve their bottom line through interchange optimization. By intelligently passing enhanced transaction data and aligning gateway settings to Level II and Level III standards, Allegiance ensures clients benefit from the lowest possible processing rates available under card brand rules. This dual focus — proactive fraud mitigation and strategic cost reduction — continues to drive Allegiance’s growth and value in the industries it serves.
