Our picks for best payment processing companies
Helcim: Best overall payment processor
Why we like it: With its volume discounts, transparent interchange-plus pricing and quick setup, Helcim is one of the best payment processors for small businesses. Businesses aren’t locked into a contract, and the merchant account provider doesn’t come with a monthly subscription charge. There are no setup fees or PCI compliance fees. Read NerdWallet’s Helcim review.
Interchange plus 0.4% and 8 cents per in-person transaction (if $50,000 or less in monthly card transactions).

Clover: Best for POS hardware options
Why we like it: In addition to handling payment processing, Clover also offers sleek POS hardware and multiple software plans for small businesses in various industries, including retail, restaurants, personal services and professional services.

Shopify Payments: Best for e-commerce platform integration
Why we like it: Shopify is a comprehensive e-commerce solution and online payment processing service that helps businesses build online stores, host them and process payments for them, among other functions. For business owners who already use the company for e-commerce, taking advantage of the payments platform makes sense, in part because an additional fee applies if you use an outside processor. Businesses get 24/7 customer support, POS software, fraud analysis, shipping discounts and the ability to sell products in dozens of currencies. Read NerdWallet’s Shopify Payments review.
2.5%, 2.7% or 2.9% plus 30 cents for online payments for Advanced, Shopify or Basic plan, respectively.
2.4%, 2.5% or 2.6% plus 10 cents for in-person payments for Advanced, Shopify or Basic plan, respectively.
Chase Payment Solutions: Best direct processor
Why we like it: Chase Payment Solutions is a direct processor, meaning it operates as both the payment processor and the acquiring bank that establishes the merchant’s bank account. So, this may be a good choice for existing Chase business customers. Additionally, Chase offers 24/7 service and has no monthly fees. It has payment processing solutions for service-based businesses, health care companies, restaurants, retail stores and e-commerce shops. Read NerdWallet’s Chase Payment Solutions review.
2.6% plus 10 cents for in-person transactions.
2.9% plus 25 cents for online transactions.
3.5% plus 10 cents for keyed transactions.
Stax (formerly Fattmerchant): Best for high-volume sales
Why we like it: Instead of charging a percentage markup per transaction, Stax charges businesses interchange plus a fixed amount of money per transaction, plus a monthly subscription fee. Although the $99 per month is steep, it could be worth it for businesses that would otherwise pay more than that in percentage markups. The merchant account provider doesn’t make its clients sign contracts, and its plans include 24/7 customer support (via an online ticketing system) and PCI compliance. Read NerdWallet’s Stax review.
Interchange plus 8 cents for in-person transactions.
Interchange plus 15 cents for manually keyed transactions.
Payline: Best for high-risk merchants
Why we like it: Payline is a great solution for businesses in high-risk industries that can’t get merchant accounts from more traditional payment processing companies. Businesses that aren’t high risk, however, have to pay for two plans if they want to accept payments in-person and online. Read NerdWallet’s Payline review.
Interchange plus 0.4% and 10 cents for in-person transactions.
Interchange plus 0.75% and 20 cents for online transactions.
Dharma Merchant Services: Best for nonprofits
Why we like it: With 24/7 customer support, no long-term contracts and no PCI compliance fees, Dharma Merchant Services is a solid choice for small businesses that process at least $10,000 of card transactions each month. The company also offers lower monthly fees and processing rates for nonprofits, which makes it a strong choice for these organizations. Read NerdWallet’s Dharma Merchant Services review.
Interchange plus 0.15% + 8 cents for in-person transactions.
Interchange plus 0.20% + 11 cents for online transactions.
Interchange plus 0.25% + 8 cents for in-person AmEx transactions.
Interchange plus 0.30% + 11 cents for online AmEx transactions.
What is a payment processing company?
A payment processing company works behind the scenes to finalize card transactions and move funds from the customer's card account to the merchant's account. While there are several steps to this process, it all takes place within a matter of seconds. Payment processors charge a fee for each transaction, and may also require a monthly software subscription.
