Cost is often a top factor when you’re looking for the right merchant account services for your business. If you process a lot of card payments each month, it can be expensive if you go with the wrong provider. There are three types of costs you need to investigate:
Processing Fees
Whether you accept credit card payments online or in person, you pay a small fee for every transaction, which is expressed as a percentage of the sale plus a few cents. However, providers calculate these costs differently, which makes it difficult to compare prices. To make an accurate comparison, you need to know the types of processing fees and pricing models.
Processing fees have three parts: the interchange rate, the card-brand fee and the processor’s markup.
- The interchange rate: This is a non-negotiable cost set by the card brands (American Express, Discover, Mastercard and Visa), and every service provider pays the same amount. Each card brand has its own rate table with different interchange rates based on the type of card (credit or debit, regular or rewards, etc.), your industry, the size of the sales ticket and how the card is accepted (in person or online, using a chip card reader or swiper, etc.).
- The card-brand fee: This is also a non-negotiable fee that the card networks charge; every processing service provider pays the same amount.
- The processor’s markup: This portion of the fee is negotiable.
When selecting a merchant services provider, it’s crucial to understand the various pricing models and their implications for your business. Here’s a breakdown of the three most common models:
1. Interchange-Plus Pricing
Considered the most transparent model, it clearly shows the processor’s markup. Fees are calculated based on the interchange rate set by card networks and the processor’s markup. This model has become increasingly popular among small businesses, as it can save merchants money compared to other pricing structures.
2. Tiered Pricing
Tiered pricing bundles interchange fees, card-brand fees, and markups into tiers. Transactions are categorized into tiers (qualified, mid-qualified, non-qualified) with varying rates. While simple to understand, this model often results in higher overall costs, with non-qualified rates sometimes exceeding 3.5 percent.
3. Flat-Rate Pricing
Flat-rate pricing consists of a single fixed percentage rate per transaction, often with no monthly fees. Popular providers typically charge 2.6 percent to 2.9 percent plus 10 to 30 cents per transaction for in-person payments, and 2.9 percent to 3.5 percent plus 30 cents for online transactions in 2024. This structure is ideal for small businesses with low transaction volumes.
Merchant Account Fees
In addition to the processing rates for each transaction, you’ll pay account maintenance fees if you’re working with a full-service merchant account provider or payment gateway service. These typically use the interchange-plus or tiered pricing models. Generally, providers that use the flat-rate processing model don’t charge account maintenance fees.
When you ask about account fees, most sales reps will tell you about the monthly fee, but there are a lot of complaints online about surprise fees on credit card processing statements. For this reason, it’s important to read the full contract (application, terms of service and program guide) to ensure you’re aware of every fee.
Here are some of the fees most merchant services providers charge. For a detailed list of fees to look for as you read processing contracts, see our guide to credit card processing fees.
- Monthly fee: Most merchant service companies charge a monthly fee, sometimes called a statement fee, that covers the cost of preparing your monthly billing statement and providing customer support. This fee typically ranges from $10 to $25, with some premium services charging up to $50 for enhanced features. Some providers may charge more if they roll other regular account fees into this charge.
- Gateway fee: A payment gateway is necessary if you intend to accept credit cards online. Small business owners with an online shop need a gateway because it encrypts and securely transmits credit card data from your website to the processor. Current pricing typically includes monthly fees of $15 to $30, with per-transaction fees ranging from $0.05 to $0.15, though some providers bundle gateway services into their overall pricing.
- PCI compliance fee: If you work with a standard processor that gives you your own merchant account, you’re required to be PCI-compliant. That designation means you adhere to the Payment Card Industry (PCI) Data Security Standard, which was developed to help merchants prevent data theft and fraud. Most processors charge between $79 and $120 annually for PCI compliance services, which includes assistance with questionnaire completion and security scans.
- PCI noncompliance fee: Even if the processor doesn’t require you to pay an annual PCI compliance fee, it may charge you a monthly noncompliance fee if you fail to establish compliance by filling out the annual questionnaire. You can easily avoid this fee by staying up to date with your PCI responsibilities. This fee typically ranges from $25 to $100 per month, reflecting increased emphasis on data security compliance.
- Chargeback fee: If a customer disputes a charge and requests their money back, the processor charges you this fee. Chargeback fees typically range from $20 to $35, with some processors charging up to $50 for international transactions. Chargebacks are more common when you accept credit cards online versus in person, because typical reasons for chargebacks include delivery failures, technical errors, fraud and customer dissatisfaction.
Avoid merchant account providers that charge an application or setup fee. The best providers won’t hit you with these extra expenses.
Equipment Costs
If you accept credit cards in person, you need to purchase a card reader or terminal. Here are the three most popular options:
- Mobile card readers: This is the cheapest option, as many providers give you a free swiper when you sign up for an account. Mobile card readers that accept EMV chip cards, contactless payments and mobile wallets typically cost between $30 and $60, with some providers offering them free with account signup.
- Credit card terminals: These devices generally cost $100 to $500, depending on functionality and connectivity options. They have built-in keypads and receipt printers, and all new models can accept both chip cards and contactless payments. Wireless and portable models with 4G connectivity tend to be priced at the higher end of this range.
- POS systems: This may be the most expensive option, but cost will depend on the type of system you choose. Tablet-based POS systems start around $300 to $500 for basic hardware, while the best POS systems can range from $1,000 to $3,000 per terminal, not including monthly software fees.
The most important thing to know about processing hardware is to avoid leasing it, because you can’t cancel a leasing contract and, in most cases, you’ll pay much more over the long term than if you purchase it outright. The Federal Trade Commission continues to warn businesses about equipment leasing scams, noting that some merchants end up paying thousands or more for equipment worth only a few hundred dollars.
