Best for online businesses
Why our editorial team chose it: With transparent, flat-rate pricing and no subscription fees, Stripe is one of the easiest payment processing solutions for online businesses.

PayPal Zettle
Best for accepting QR code payments
Why our editorial team chose it: PayPal Zettle’s low card-present transaction rates — which also apply to QR code payments — and free POS app make it an affordable option for service-based businesses and solopreneurs selling at markets or popups. To accept a QR code payment, you enter the sales total into the app, choose PayPal or Venmo as the payment method and ask your customer to scan the QR code that the app generates. Since processing online transactions may involve separate payment gateway subscriptions, it’s not the best choice for businesses making the bulk of their sales online. Read our full PayPal Zettle

How to calculate credit card processing costs
To predict your business’s monthly credit card processing fees, start by determining your average card transaction amount and how many card sales you complete each month. From there, you can use this calculation to estimate your monthly credit card processing costs for specific types of transactions (e.g., online, in-person or keyed-in):
[(average credit card transaction dollar amount x transaction percentage fee) + transaction fixed fee] x [number of credit card sales completed per month]
Here’s a breakdown of credit card processing fees, plus other associated costs.
Credit card processing fees
Credit card processing fees vary by provider and which fee structure they use: interchange-plus or flat-rate. Generally, interchange-plus

How to choose the cheapest credit card processing company
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 authorize and complete card transactions. However, carefully weighing credit card processing companies can guide you toward the most cost-effective option.
To find the cheapest credit card processing company for your business, consider the following factors:
Your industry
Typical transaction size
Sales volume
Convenience
Tips for reducing credit card processing fees
While you can’t avoid credit card processing fees altogether, there are several strategies for reducing the burden on your business.
Incentivize customers to pay with cash
Certain credit card processing companies offer credit card surcharge
Implement minimum purchase amounts
Paying processing fees on a small transaction amount, like $3, might not be worth it for your business. If that’s the case, consider implementing a minimum credit card purchase amount and require customers to use cash if their receipt total is below the minimum.
Request a volume discount
Some credit card processing companies
Consider interchange-plus over flat-rate pricing
Interchange-plus pricing passes interchange fees, plus a set markup, to the merchant. This means that the merchant pays less when customers use cards with lower interchange fees. Many times, this pricing model is more cost-efficient, but less predictable, than flat-rate pricing.
Negotiate markups
If you go with an interchange-plus processor, you might be able to negotiate how much they charge on top of interchange fees. Prior to having that conversation, though, make sure you have the figures ( e.g., your monthly processing costs, average transaction amount, how your processor‘s markups compare to competitors) to back up your request.
Make sure your interchange fees align with your industry
When you start accepting credit card payments, your business is assigned a merchant category code based on its industry and what it sells. That code determines your interchange rate, among other factors. If you use an interchange-plus processor that passes fluctuating interchange rates to your business (instead of charging a consistent fee, like flat-rate processors), ensuring your business is assigned the correct code can help guarantee you’re being charged the appropriate interchange fees for your industry type.
