Past every pricing threshold
A $1,000,000 store averages more than $83,000 in monthly card sales. The U.S. Chamber CO guide puts the point where interchange-plus typically gets cheaper at $10,000 a month. The JIM 2026 guide puts the flat-rate crossover near $50,000.
Seven-figure stores clear both by a wide margin, yet many still pay one flat online rate on every sale.
