Focus on Markup
A credit card processor makes money by charging a markup over its costs of interchange and assessments. (That is, the "wholesale" cost noted above.) The lowest cost processor is the one that charges the lowest markup, and obtaining the lowest markup means understanding some tricks of the trade.
Pricing Model
Credit card processors use various pricing models to pass the components of processing cost to businesses. By far the most widely used pricing model is something called
tiered pricing. As explained in detail in CardFellow's
credit card processing guide, tiered pricing allows a processor to conceal costs and levy hidden surcharges.
Tiered pricing is also the pricing model that leads people to shop for processing companies based on the "best rates." For reasons outlined in the aforementioned guide, tiered pricing is expensive and opaque. It is not the ideal pricing model.
Interchange plus pricing is the first step toward a low processing markup. CardFellow's article about
interchange plus pricing explains the benefits of this pricing model in detail, and it outlines exactly why interchange plus is the first step toward securing a competitive processing solution.
Terms
An often overlooked aspect of an advantageous processing solution is the terms a processor employs. Cost is important, but it's not the only variable to consider. Things like cancellation charges and longevity are important, too. You don't want to get locked in with an expensive processor that charges a hefty cancellation fee. Likewise, if you do obtain a good, low-cost solution, you want to be able to keep that processor at those terms for awhile.
CardFellow does not allow processors in its marketplace to charge cancellation fees. We also require interchange vouchers on
credit card refunds, and pricing is guaranteed to remain locked for the life of an account, so you're not subject to random markup hikes once you've locked in your low cost processing. These are important variables to consider if you're shopping for processing on your own.
