PROCESSING COSTS

What Are You Really Paying to Accept Cards?

A low advertised rate is only part of the picture. Before comparing providers, understand what you pay across a normal month and which services are included.

THE TAKEAWAY

Compare the total cost for the way you accept payments, rather than a single percentage.

Know what sits behind the rate

Card acceptance costs can include interchange, card network charges and the provider’s own fees. Visa explains that interchange is a transfer between banks; the merchant pays its financial institution for processing services. A provider may bundle costs together or show them separately.

Read more than the transaction line

Review your statement and agreement for monthly service charges, gateway or software fees, equipment costs and charges associated with disputes. Ask which apply to your account and which are optional. A fee is easier to assess when you know the service behind it.

Make the comparison meaningful

Use a monthly snapshot carefully

Dividing the processing fees you identify by the related card sales gives you a useful starting point. Keep the same cost categories in both comparisons. One unusual month, a different card mix or a separate equipment bill can distort the result.

The question is whether the complete arrangement fits your business, including its service and equipment needs.
