A fee charged by some processors if a merchant's monthly processing fees fall below a set threshold. For example, if a processor has a $25 monthly minimum and the merchant's processing fees only total $10, the merchant pays an additional $15 to meet the minimum. This fee effectively ensures the processor earns a minimum revenue regardless of the merchant's transaction volume.
The minimum monthly fee works differently from a standard service or account fee. A monthly service fee is charged every month regardless of how much you process. The minimum monthly fee is conditional — it applies only in months when your total processing fees fall short of the processor's specified floor. Merchants with consistent volume may never trigger it; those with seasonal slowdowns, occasional sales activity, or variable month-to-month volume are most likely to encounter it. The key question to ask a processor is not just the minimum amount, but when it typically applies and how it is calculated.
No. It applies only in months when your total processing fees fall below the threshold. In months where you process enough volume to generate fees above the minimum, the minimum fee does not apply. Active merchants with consistent volume often never pay it.
A monthly service fee is a fixed charge that applies every month regardless of processing volume. A minimum monthly fee is conditional — it functions as a floor for your processing fees. You pay it only when your processing activity doesn't generate enough fees to reach the minimum. In a high-volume month you owe nothing toward the minimum.
Seasonal businesses, part-time sellers, event-based merchants, or any business with highly variable month-to-month processing volume. Low-volume months — where processing fees are naturally small — are when the minimum is most likely to apply. If you expect periods of reduced activity, ask for the minimum amount before signing and factor it into your cost estimates.
