- Easy to understand
- Interchange fees and markups are bundled together
- Fee breakdown isn’t very transparent
- Ideal for new businesses that don’t process a lot of credit cards
One of the most popular examples of a company that uses this pricing structure is Square.
Square’s fee is a flat 2.6% + $0.10 for contactless payments, as well as swiped and inserted credit card payments. Meanwhile, keyed-in credit card transaction fees are 3.5% + $0.15 per transaction. This means that you pay those same percentages for every transaction regardless of the type of card used or the industry you’re in.
While this seems simple, it may end up costing you much more money over the long term. This is because flat-rate credit card processing bundles up the interchange fees with the processor’s markup.
Interchange rates are variable and can range from 0.05% to 3.17% depending on factors like the type of card used, processing method, etc.
That said, the average interchange rate is 1.81% for credit card payments and 0.3% for debit cards. It’s also important to note that interchange fees are paid to the issuing bank and are determined by credit card brands like Visa and Mastercard.
When you’re on a flat rate percentage structure like Square’s, you’d be paying at least 2.6% per transaction even if the interchange cost related to that sale is often significantly lower.
So, while the payment structure is easy to understand, it’s not always the most cost-effective option. That’s because you are almost always paying more than the interchange rates, which is the direct cost of processing. The rest of what you pay belongs to the payment solutions provider.
