Payment gateway technology in the late 1990s was being invented in real time — there were no established standards, no dominant platforms, and no clear model for what a payment gateway should actually do for a merchant. Computop was founded in Bamberg in 1997 and has spent nearly three decades building and refining one of Germany's most comprehensive payment platforms, evolving from an early web payment solution into a multi-channel payment gateway covering online, in-store, and mobile commerce. Its Paygate platform handles payment acceptance across dozens of payment methods, currencies, and markets, with particular depth in the DACH region and a growing international footprint. Computop has built strong relationships with major German retailers and e-commerce operators, becoming the payment platform of choice for a significant share of German online commerce. In a payment gateway market that has been reshaped repeatedly by technology shifts — from dial-up to broadband, from web to mobile, from hosted to API-first — Computop's longevity reflects the ability to modernise its technical architecture while maintaining the merchant relationships and payment method coverage that took decades to assemble. For German merchants seeking a gateway with genuine local depth combined with international capability, Computop remains a reference point.
