How To Avoid B2B Credit Card Processing Fees

Key takeaways

• Compare the true cost of each payment method, since checks, wires, and standard ACH all carry time or fees that eat into B2B margins.
• Break processing fees into interchange, network, and processor charges so you know exactly what you pay and where.
• Lower your costs by surcharging compliantly, negotiating your processor rate, or steering customers toward lower-cost methods like ACH.
• Accept cards at little to no cost by using Melio to pass the fee to customers or absorb it while getting paid in full.

What’s stopping B2B credit card payments?

The average US consumer has about 3.7 active credit cards. In the B2C industry, businesses have little choice but to accept credit cards or lose customers.

For B2B companies, payment methods such as direct deposits, wire transfers, and checks are still the most common and popular. Business owners may be less inclined to change their ways and make the move to accept credit cards.

They may be even more reluctant about the cost of credit card processing fees and how it could affect their business’s bottom line.

On the upside, credit card transactions are processed on the spot, so businesses can get payment confirmation instantly. This eliminates the time spent waiting for checks in the mail and depositing them in the bank. Checks can also get lost or stolen, or simply bounce, further distancing you from the money at the end of the tunnel.

Avoiding card fees can feel like a short-term win. Over time, though, B2B customers who prefer cards may take their business elsewhere to find the flexibility they want. By not accepting cards, you could be leaving customers and revenue on the table.

How businesses pay businesses, and why they’re doing it wrong

B2C businesses are typically flexible with their payment methods. Even if they choose to avoid the high fees of traditional credit card processors, B2C companies have more payment alternatives to offer customers, such as mobile payment apps.

Business transactions, on the other hand, can be complex and rigid, leaving just a few payment options, including cash, wire or bank transfers, and paper checks.

Here’s why these are not always ideal for business payments:

• Cash: Many B2B businesses work with high volume payments. They may be selling inventory in bulk, or dealing with expensive bills for equipment and services. Paying in cash is not a safe or realistic option. In many countries, caps have been placed on cash payments limiting the amount that can be paid in cash, making large cash payments impossible.

Bank transfers: ACH bank transfers are a convenient, inexpensive way to pay business bills. However, standard transfers typically take one to two business days to settle. This makes them less appealing when a bill is due or there’s an early bird discount to collect. Wire transfers are faster, arriving within 24 hours, but they’re expensive, usually costing around $25 to $30 per transaction.

• Checks: This classic payment method is highly subject to fraud and theft. It’s also cumbersome, prone to error, and surprisingly expensive once you factor in labor, materials, postage, and reconciliation.

Different components of processing fees

There is no such thing as a free lunch, and there is no such thing as a free credit card payment either.

There are many parts to the credit card transaction, with several fees along the way (many of which are hidden). Let’s take a look at the different types of processing fees that make up the overall cost of B2B credit card payments:

• Interchange fees: These are the fees paid by the merchant’s bank (acquiring bank) to the cardholder’s bank (issuing bank) whenever a credit card transaction is processed. It covers the risk involved for the issuing bank in approving and handling the payment.

For example, Business A pays a bill for $10,000 worth of office supplies from Business B, using a Visa credit card. Let’s say that the interchange fee is 2.25% + $0.10.

Visa forwards $9,774.90 to Business B’s bank account ($10,000 minus the interchange fee of $225.10). The $225.10 interchange fee is kept by the issuing bank as compensation for handling the transaction.

• Network fees: There is a complex network behind the scenes that facilitates credit card transactions. The network is made up of credit card companies, payment processors, banks, and financial institutions. Various activities in the network incur fees, including:

1. Batch fees go towards closing out and settling the batch of daily transactions.
2. Assessment fees are charged by the credit card networks (ie, Visa, American Express, etc) to the acquiring bank for each transaction.
3. Processor markup fees are additional fees that may be charged by the payment processor for handling the transaction.
4. PCI compliance fees ensure that a merchant complies with the Payment Card Industry Data Security Standard (PCI DSS), required for handling credit card data.
5. And more.

• International fees: Transactions involving international cards or currencies incur additional processing fees and currency exchange fees. This is a percentage of the transaction amount, typically higher than domestic charges.
• Chargeback fees: When a customer disputes a credit card transaction and the issuing bank reverses the charge, the business pays a chargeback fee. Different card processors charge different amounts for chargeback fees. Maintaining comprehensive payment records is essential to avoid payment disputes and chargeback fees.

How much does it cost to accept credit cards?

Accepting credit cards usually costs between 1.5% and 3.5% of each transaction. The exact rate depends on the card type, your payment processor, and your transaction volume, and online payments tend to sit at the higher end.

Across Visa and Mastercard, the average effective swipe fee was about 2.36% in 2025. Fees like these add up and can dent net profit margins, especially on larger B2B payments.
