A robust plug-and-play payment infrastructure for software developers
Seamless onboarding
Send pre-filled, electronic applications to your merchants. Set up new clients without the headaches of paperwork or signatures.
Instant account approval
Skip the manual underwriting process with instant approval for your merchant accounts. Our system will run Know Your Customer (KYC) checks to verify identity, assess financial health, and monitor risks.
Simple, flat-rate pricing structure
Transparent and consistent pricing gives your merchants predictability when managing overhead costs — no more surprise charges at the end of the month.
No monthly statement or PCI fees
Save your merchants time — no more combing through monthly statements to reconcile charges.
Omnichannel capabilities
Whether your merchants do business online or in-store, they’ll get the flexibility they need while ensuring secure transactions.
White-Glove Customer Service
Cardknox offers a single phone number to get the help you need now — as opposed to other providers who keep you waiting days for an email reply. Our customer support teams are based in the U.S. and deliver a white-glove, hands-on experience — for any type of merchant or developer support.
