Demystifying Payment Fees: Understanding Interchange, Processing, and Gateway Fees (and How to Save Money)

When it comes to accepting payments, many business owners face confusing fee structures that seem to chip away at their profits. Terms like interchange fees, processing fees, and gateway fees are often used interchangeably, but they refer to different parts of the payment chain—and understanding them is key to optimizing your payment operations and reducing costs.

In this blog, we’ll break down what these fees are, why they’re charged, and how your business can save money by making smarter payment decisions.

1. What Are Interchange Fees?

Interchange fees are fees set by credit card networks (such as Visa, Mastercard, or Amex) that are paid to the bank that issued the customer’s card. These fees compensate issuing banks for the risk and convenience of allowing customers to use their credit cards.

Key Factors That Affect Interchange Fees:

• Card Type: Premium rewards cards typically have higher interchange fees than standard debit cards.

• Transaction Type: In-person transactions usually have lower interchange fees compared to online or keyed-in transactions.

• Merchant Category Code (MCC): Different industries have different interchange rates based on their assigned MCC.

Typical Cost:

Interchange fees usually range between 1.15% to 3% of the transaction amount, depending on the above factors.

2. What Are Processing Fees?

Processing fees are charged by the payment processor—your service provider that facilitates the transaction between the cardholder’s bank, the card network, and your business. This fee compensates the processor for handling the technical aspects of the transaction, such as authorization, settlement, and reporting.

Components of Processing Fees:

• Flat Fees: A fixed fee per transaction (e.g., $0.10 per transaction).

• Percentage Fees: A percentage of the transaction value (e.g., 0.5% to 1%).

• Monthly Fees: Some processors charge a monthly service fee in addition to per-transaction fees.

Typical Cost:

Processing fees vary but typically fall between 0.5% to 1% of the transaction, plus a flat fee per transaction.

3. What Are Gateway Fees?

A payment gateway is a technology that securely transmits cardholder data between the point of sale (POS) or website and the processor. Think of it as a secure digital "tunnel" that encrypts and routes sensitive information.

Common Gateway Fees:

• Monthly Fee: A flat monthly fee for using the gateway (often $10–$50).

• Per-Transaction Fee: A small fee (e.g., $0.05–$0.15) per transaction routed through the gateway.

• Batch Processing Fees: A fee charged for closing out daily transactions and sending the batch to the bank for deposit.

Typical Cost:

Gateway fees can range from $10–$50 per month plus $0.05–$0.15 per transaction. Some providers offer bundled services that combine processing and gateway fees, but these bundles may come with higher markups.

4. Why These Fees Add Up and Hurt Your Bottom Line

• High Interchange Fees on Rewards Cards: If many of your customers use premium rewards cards, you may be paying higher interchange fees without realizing it.

• Flat-Rate Processing Fees: Flat-rate providers (e.g., Stripe, PayPal) may seem convenient, but the lack of interchange optimization means you could be paying a higher blended rate than necessary.

• Bundled Gateway and Processing Fees: Some POS providers lock merchants into exclusive agreements that bundle fees, leading to higher overall costs due to limited flexibility.

5. How to Reduce Payment Fees and Save Money

5.1 Optimize for Lower Interchange Rates

• Encourage Debit Card Usage: Debit cards have significantly lower interchange fees than credit cards.

• Submit Complete Transaction Data: Providing extra data points (such as invoice number and customer details) for B2B transactions can qualify you for lower interchange fees.

• Ensure Your MCC Code is Correct: A misclassified MCC could be causing your business to pay higher interchange rates.

5.2 Choose a Processor with Transparent Pricing

Look for processors that offer:

• Interchange-Plus Pricing: This pricing model passes interchange fees directly to you with a transparent markup, so you know exactly what you’re paying.

• No Hidden Fees: Avoid providers that charge additional fees for services like refunds or PCI compliance without disclosure.

5.3 Avoid POS or Gateway Lock-Ins

• Some POS systems require you to use their default payment processor, which often comes with higher rates. Consider choosing systems that allow you to integrate with third-party processors so you can shop for the best rates.

5.4 Negotiate for Volume Discounts

If your transaction volume is high, you may be able to negotiate lower processing rates with your provider. Processors often offer discounted rates to high-volume merchants.

5.5 Bundle Smartly (But Be Careful)

Some providers bundle gateway and processing fees into a flat monthly rate. If your transaction volume is consistent and predictable, this may save you money—but be wary of high markups and long-term contracts.
