Frequently asked questions

Is interchange-plus cheaper than flat-rate?
For established businesses with consistent volume, interchange-plus is usually cheaper because you pay the real interchange cost plus a small fixed markup instead of a blended rate. Very small or new businesses may still prefer flat-rate simplicity.
What does interchange-plus mean?
Interchange is the fee the card networks charge; 'plus' is your processor's fixed markup on top. Because the two are itemised, you can see exactly what you're paying, unlike tiered or blended pricing.
