Supported Payment Processors

This question asks which payment companies the vendor's system can work with—like Stripe, PayPal, Square, or traditional processors like First Data. It's asking about compatibility, similar to asking which types of credit card readers work with their point-of-sale system. This determines whether their system will work with your existing payment setup or preferred processors.

Payment processor compatibility directly impacts your operational costs and revenue capabilities. Switching processors can cost $10,000-$50,000 in integration and testing, while incompatibility might force you to use more expensive processors, increasing transaction fees by 0.5-1%. Supporting multiple processors provides redundancy, preventing revenue loss from processor outages that can cost thousands per hour.

Companies often overlook processor-specific compliance requirements—each gateway may have unique security obligations beyond PCI DSS. Another mistake is not considering international payment needs; a processor that works well domestically might not support international transactions or currencies you need for growth.
