Interchange-plus
Also known as: Interchange++, Cost-plus pricing
A transparent pricing model: true interchange cost plus a fixed processor markup.
Interchange-plus pricing itemises your cost as the network's interchange fee plus a fixed markup (for example, interchange + 0.30% + $0.10). Because the two parts are separated, it's the most transparent model and usually the cheapest once you have steady volume. Compare it with flat-rate and tiered pricing.
