Practical checklist
How to avoid overpaying on card machine fees
-
Ask the right questions
Ask whether the quoted rate is "blended" (one flat rate for all cards) or "interchange-plus" (a smaller markup on top of the card networks' actual cost) interchange-plus is usually cheaper for higher-volume businesses.
-
Your monthly transaction volume affects your rate too.
Check for a minimum monthly charge that kicks in if your transaction fees don't reach a set threshold.
-
Check for hidden charges
Get the PCI compliance and early termination terms in writing before signing, not just the headline transaction rate.
