When you accept credit or debit cards, you’re not just getting paid—you’re paying a fee for the privilege. This is card processing costs, the fees merchants pay every time a customer uses a card to pay for goods or services. Also known as merchant fees, these charges are built into every transaction and often hidden in fine print, making them one of the most overlooked expenses in small business finances. Unlike rent or payroll, these costs creep up silently—sometimes as low as 1.5%, sometimes over 3.5%—and they add up fast. If you process $50,000 a month in sales, a 1% difference means $500 a month, or $6,000 a year, just gone.
These fees aren’t one-size-fits-all. They’re made up of several layers: the interchange fee, the base cost set by card networks like Visa and Mastercard, paid directly to the customer’s bank, plus the assessment fee, a small percentage charged by the network itself, and finally, your payment processor markup, the profit your provider takes on top. Most businesses only see the final number on their statement and assume it’s fixed. But it’s not. The markup is negotiable. The interchange fee changes based on how the transaction is processed—swiped, dipped, keyed in, or online. And if you’re using a flat-rate plan, you’re likely overpaying on low-cost transactions.
Some processors hide fees under names like "batch settlement," "statement fee," or "PCI compliance fee." These aren’t taxes—they’re revenue. And they’re not optional. You’re paying them whether you know it or not. The biggest savings come from understanding your transaction mix. A business that takes mostly swiped in-person payments pays far less than one that relies on keyed-in online orders. If you’re running an e-commerce store, your costs are higher. If you’re a restaurant taking tableside payments, you can get better rates. Your processor should be able to break down your last 30 days of transactions and show you exactly where the money’s going. If they can’t—or won’t—you’re being treated like a commodity, not a customer.
There’s no magic trick to eliminating these fees entirely. But you can slash them by 30% or more just by asking the right questions. Switching to interchange-plus pricing instead of tiered or flat-rate plans is the single biggest move most businesses can make. Ask your processor: "Can you show me the interchange rate for each transaction?" If they hesitate, walk away. Look for providers that don’t charge monthly fees, statement fees, or early termination penalties. And don’t get locked into multi-year contracts—those are designed to trap you, not help you.
