Frequently Asked Questions

Is membership pricing better than flat-rate or interchange-plus?

Membership pricing can reduce total processing costs for businesses processing $50,000 or more per month. At lower volumes, the monthly membership fee may outweigh the savings. Use the Cost Calculator on ProcessorFit to estimate based on your specific volume and average transaction.
