Processing rates go down after your business processes more than $25,000 in payments per month.
Cons:
Doesn't work with high-risk merchants, meaning businesses that are more susceptible to fraud and chargebacks.
No 24/7 support.
Why we like it: Helcim is a fantastic choice for small businesses looking for low rates and no monthly subscription fees. Its interchange-plus fee structure is a cost-effective option, especially for businesses with high sales volumes, and its website makes it easy to find pricing information. The company's volume discounts, which are applied automatically as the amount you process increases, are a nice perk to have as your business grows.
Square: Best for mobile payments
Pricing:
2.6% plus 10 cents for in-person transactions (2.5% plus 10 cents with Retail Plus plan).
2.9% plus 30 cents for online transactions or invoices without a card on file.
3.5% plus 15 cents for manually keyed transactions or card-on-file invoices.
Pros:
No early termination, activation, refund or chargeback fees.
No PCI compliance fees.
No monthly subscription fee.
Free point-of-sale software.
Free mobile card reader.
Cons:
May be more expensive than an interchange-plus pricing model for some businesses.
Doesn't work with high-risk merchants.
Only paid POS plans include 24/7 live customer service.
Why we like it: With clear, flat-rate pricing, free POS software and a free mobile card reader, Square is one of the cheapest credit card processing solutions, especially for smaller businesses. 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. Square offers Tap to Pay on iPhone, which lets merchants accept card payments using only a regular iPhone with the Square POS app. API integrations let clients accept credit cards on their website or e-commerce site, too.

Stax (formerly Fattmerchant): Best for membership-style pricing
Pricing:
Interchange plus 8 cents for in-person transactions.
Interchange plus 15 cents for manually keyed transactions.
$99 per month and up for software.
Pros:
No contracts.
24/7 technical support.
Offers add-ons like custom branding and same-day funding.
Cons:
Not ideal for low-volume small businesses.
Why we like it: Instead of charging interchange fees plus a percentage markup per transaction like some of its competitors, Stax requires its clients to subscribe to a monthly plan and charges interchange plus a fixed per-transaction fee, which is 8 cents for in-person transactions. This fee structure could help high-volume businesses save money, especially if they’d otherwise pay more than $99 per month in percentage markups and other fees. The monthly price does increase for businesses that process more than $500,000 annually, but Stax works with those business owners to build custom packages that still result in savings.
Payline Data: Best for high-risk merchants
Pricing:
Interchange plus 0.4% and 10 cents for in-person transactions, and $10 per month.
Interchange plus 0.75% and 20 cents for online transactions, and $20 per month.
Pricing varies by card type for manually keyed transactions.
Pros:
No long-term contract or cancellation fees.
No PCI compliance fees.
Offers high-risk merchant accounts.
First month is free.
24/7 phone support.
Cons:
Negative user reviews.
Why we like it: Payline Data is a merchant account provider that offers interchange-plus pricing at very low rates. It has two plan offerings, one designed for brick-and-mortar retailers and one designed for e-commerce merchants. While 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. It also offers high-risk merchant accounts for businesses involved in industries such as tobacco, online gaming, fantasy sports, self-storage and more.
Payment Depot: Best risk-free trial
Pricing:
Interchange + $0 per transaction, plus $59 month for Starter plan.
Interchange + $0 per transaction, plus $79 month for Starter Plus plan.
Interchange + $0 per transaction, plus $99 month for Growth plan.
Pros:
Includes a free virtual terminal for keying in credit card numbers.
All memberships come with a 90-day trial during which your annual membership fee will be refunded if you cancel.
No cancellation fees.
Includes PCI compliance.
24/7 support available (although it isn’t entirely in-house).
Cons:
Maximum processing limits apply to all plans.
Doesn't work with high-risk merchants.
Why we like it: Payment Depot is a merchant account provider owned by Stax. It offers a 90-day trial; if you cancel your account before this period ends, it will refund your annual membership fee. Plus, all plans include free programming of any existing equipment you own and a free virtual terminal, which lets stores key in credit card numbers when the card isn't present.
Stripe: Best selection of tools and features
Pricing:
2.9% plus 30 cents for online transactions.
2.7% plus 5 cents for in-person transactions.
3.4% plus 30 cents for manually keyed transactions.
3.9% plus 30 cents for international cards or currency conversion.
Pros:
No setup fees.
No monthly subscription fees.
24/7 phone, chat and email support.
More than 450 platforms and extensions available.
Accepts payments in more than 135 currencies.
Cons:
Doesn’t work with high-risk merchants.
Why we like it: With transparent, flat-rate pricing and no subscription fees, Stripe is one of the easiest payment processing solutions for online businesses. Although you may find an alternative provider with lower processing fees, it’s difficult to beat the lack of other fees, flexibility and included-payment tools within the company's platform. The payment service provider offers its own invoicing, billing, business data and tax calculation features, too.
Dharma Merchant Services: Best for nonprofits
Pricing:
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.
Pros:
No long-term contracts or early termination fees.
Includes access to a free virtual terminal and online reporting.
No PCI compliance fees (although there is a $39.95 monthly fee for those that become noncompliant)
24/7 support.
Cons:
Monthly fee required.
Doesn’t work with high-risk merchants.
Why we like it: Dharma Merchant Services charges nonprofits reduced monthly fees and processing rates, making it a top choice for these organizations. It's also a certified B Corp, meaning it's held to higher environmental and social standards. That’s a big plus for small businesses that pride themselves on working with socially responsible companies. The company also offers reduced rates for small businesses that process over $100,000 per month.
National Processing: Best variety of industry-specific plans
Pricing:
Restaurant: interchange plus 0.14% and 7 cents per transaction.
Retail: interchange plus 0.18% and 10 cents per transaction.
E-commerce: interchange plus 0.29% and 15 cents per transaction.
Subscription: interchange plus 9 cents per transaction.
Subscription Plus: interchange plus 5 cents per transaction.
Pros:
Works with high-risk merchants.
Offers several good integrations for accounting, online selling and shopping carts.
Each plan includes free reprogramming of existing hardware plus a free mobile card reader.
Cons:
National Processing’s payment processing fees are only guaranteed for merchants that process at least $10,000 in sales a month.
Monthly fees can add up.
Requires a long-term contract, and there are early termination fees (with a few exceptions).
Why we like it: National Processing is a payment processor with competitive rates, useful integrations and compatibility with several card readers. Plus, it works with high-risk merchants. Its long-term contracts are a concern, but every plan includes free reprogramming of existing equipment and some free hardware.

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.
