What is Fattmerchant?
Fattmerchant, now branded as Stax, is a payment processing platform for small and mid-sized US businesses that charges a flat monthly subscription plus interchange cost rather than a per-transaction markup, which lowers effective rates for businesses processing higher payment volumes. It bundles a virtual terminal, invoicing, and merchant account services in one platform, reducing the complexity of working with multiple payment vendors. The subscription model requires a minimum monthly volume to break even versus percentage-based processors, so lower-volume merchants should compare total cost carefully.
