Because credit card processing companies come with various pricing structures, no one provider is the cheapest for all businesses. The least-expensive choice depends on your industry, sales volume and typical transaction size.
Before making a decision, it's important to determine what the best credit card processing company for your business would need. What capabilities and tools do you require? Do you need a dedicated merchant account? Will you be accepting payments in person, online or both? Narrow down the options based on these requirements, then see which provider will offer the cheapest payment processing for your business.
Here are eight affordable credit card processing companies to consider.

Businesses can use the payment service provider to accept a variety of payments, including both in-person and online. To process in-person payments, for example, you can use free POS software alongside one of its hardware options. Businesses can also opt for Square's retail POS or Square's restaurant POS software plans to access more features.

Although paying for both plans isn't ideal for businesses that sell products both online and in stores, it could be one of the cheapest options for businesses that require only one or the other.

Frequently Asked Questions
The short answer is no. If you want to offer your customers the option to pay by card, whether in person or online, you will need to pay fees to credit card companies and financial services providers to enable them to authorize and complete card transactions.
Learn more about credit card processing fees and use NerdWallet’s credit card processing fees calculator to better determine what processing fees could look like for your business.
There is no standard credit card processing fee as fees vary by provider and fee structure. On average, however, credit card processing fees range from 1.5% to 3.5% of the total transaction cost.
The best merchant service provider for your business will ultimately depend on your industry, sales volume and typical transaction size. If you process a low volume of transactions, you may find providers such as Square and Stripe are a good fit since they both offer clear, flat-rate pricing and lack some of the fees other providers charge, such as monthly subscription, setup, PCI compliance and early termination fees.
Credit card processing fees: These fees fall into one of three pricing structures: tiered, interchange-plus and flat-rate. Generally, interchange-plus is the preferred pricing structure for credit card processing fees because it’s the most cost-effective for businesses with high sales volumes. However, flat-rate pricing can be more predictable and easier to understand.
Hardware or software fees: Chances are you’ll need to buy hardware and subscribe to a software plan to accept payments, such as a POS terminal that doubles as your register or a mobile card reader you plug into a smartphone or tablet. Sometimes, the POS system will include the software.
Other fees: Depending on the processor, you may have to pay a variety of flat fees for their service. The most common is a monthly subscription fee to work with the processor. You might also be subject to flat fees for services like PCI compliance, setup, cancellation, funds withdrawal and more. Merchant account providers are often criticized for their lack of transparency with these types of flat fees, so you’ll want to be sure you’re clear on the terms of your contract.
