If you own a small business, you likely know that payment processing is crucial to keeping your enterprise running smoothly. In fact, fees on U.S. card swipes (both credit and debit) totaled a record $198.25 billion in 2025, showing what a major role processing plays in the economy.
To help you manage this aspect of your business as effectively as possible, consider this guide to small business payment processing and learn about how it works, what kind of fees to expect, and more.
Key Points
• Small business payment processing enables merchants to securely accept credit cards, debit cards, and digital wallets, facilitating smooth transactions from customers to sellers.
• During processing, transactions are authorized, batched, and funds are transferred from the customer’s card-issuing bank to the merchant’s business account.
• Businesses can accept payments through traditional merchant accounts or payment service providers.
• Processing costs typically range from 1% to 3% per transaction, making it essential to factor these fees into business overhead and overall budgeting plans.
• To select the right system, evaluate your transaction volume, business model, security needs, and total costs to find a provider that aligns with your specific goals.
What Is Small Business Payment Processing?
Small business payment processing is the method that allows merchants to accept non-cash transactions. It’s the system that allows for credit card, debit card, and digital wallet payments to be accepted and securely transferred from the purchaser to the seller. Like small business loans and other financial products, it can be an important part of launching and growing your enterprise.
How Payment Processing Works
Here’s a more in-depth look at how payment processing works for small businesses.
• The customer initiates payment at a point-of-sale terminal with their chosen payment method.
• The details of the transaction are transmitted to the card-issuing bank for validation. If verified, the card-issuing bank sends an authorization so the transaction can proceed.
• The transaction is then batched with others to be completed, usually at the end of the business day. This involves the payment processor moving funds from the customer’s card-issuing bank to the merchant’s account, such as a small business checking account. The merchant’s financial institution then credits the connected account with the funds for the transaction, subtracting any transaction fees.
Payment Options for Small Businesses
If you run a small business, you likely know that there are multiple ways you can accept payments. Consider these two main avenues: in-person and online.
In-Person Payment Methods
In-person payment methods often involve a few ways that a customer can pay for goods or services. As a small business owner, you might accept cash, checks, or digital wallets and credit and debit cards via a point-of-sale (POS) terminal. It can be a wise move to accept several options since customer needs may vary.
When it comes to accepting card and digital wallet payments, there are two resources you may want to consider:
• Merchant account providers: These are banks and certain other companies that offer merchant bank accounts. These accounts come with a suite of tools that allow a business to accept card and digital wallet payments. Many small business owners may already have this kind of account.
• PSPs (or payment service providers) are another option. These are businesses like Stripe and Square that aggregate business accounts and allow these companies to accept payments without setting up a merchant account.
Online Payment Methods
If you want to accept payments online, you likely have choices, as noted above. You may have or open a merchant bank account that provides you with methods for accepting card and digital wallet payments as part of their offerings to help you manage and grow your business.
Or you might select a payment service provider, a business that allows you to accept payments online without having a merchant account.

Payment Processing Fees: What to Expect
It is common to pay processing fees when you are a small business owner. These charges typically land in the 1% to 3% range. Mastercard- and Visa-branded credit cards dominate the market, controlling 80% of the market, and their swipe fees were 2.36% in 2025.
It can be wise to factor in such costs as part of your business overhead when budgeting.
Depending on your particular situation, you may want to look into a small business line of credit for flexibility in managing your small business expenses from launch through scaling.
Best Payment Processing for Small Businesses
The best payment processing for small businesses is the one that best suits your small business needs. There are many factors to consider; then, it can be helpful to research options and tap your trusted network of friends and advisors before making a decision. Here are some considerations:
• Do you do most of your business in-person or online/mobile?
• Do you have a custom website that processing will be integrated into? Is yours a social-media-driven business?
• Do you offer subscription models?
• Is your business domestic or international?
• Are you (or do you anticipate being) a low- or high-volume business? How quickly do you plan to scale your business?
• What is your budget for processing fees?
• What security protocols are you most interested in?
• Do you already have a relationship with a financial institution for your business?
While there are a number of considerations, knowing your key needs and concerns for payment processing can help you evaluate your options and choose the best partner.

How to Choose the Right Payment System for Your Small Business
If you’ve considered your needs, as described above, your next step may be to assess payment processing providers so you can make your decision. You might consider these points to help you make a choice.
• Consider your current sales figures, such as transaction volume, typical size of sale, and which payment methods are most popular. Determine which payment processor syncs with your business model and your plans to scale.
• Dig into the details of the all-in costs of different payment processing options so you can work to determine which option is the best financial fit. It’s also worth looking into how flexible a contract with a payment processing system is. Would there be a charge, say, for ending services early?
• Check reviews. As with most purchases and partnerships, it can be wise to fully vet contenders. Payment processing systems may offer demos and free trials, which can inform your decision.
• When you have a couple of top contenders, it may be helpful to create a pros and cons list so you can compare your alternatives in terms of services offered, pricing, and other key features.

FAQ
What is the cheapest payment processing for small businesses?
The cheapest payment system for small businesses will depend on several factors, such as the size of your business and the features and flexibility needed. It can be wise to compare what services your financial institution (if you currently hold a merchant account) offers vs. third-party providers to determine the most cost-effective option.
What is the difference between a payment gateway and a merchant account?
A payment gateway and a merchant account are business tools that together allow your business to accept online credit card payments. A payment gateway transfers card details from the website to the banks involved so payments can be transferred, while a merchant account is responsible for receiving and holding funds.

What is interchange-plus pricing?
Interchange-plus pricing is a method of passing the broken-out cost of every card swipe (the interchange fees) along to your business versus packaging it into a blended rate. This transparent pricing strategy shows you the wholesale interchange fee, the network assessment fee, and a fixed processor markup. It can allow you greater insight into your small business costs.
