What is the best credit card processing for a small business?
It depends on how you sell. Square is our starting point for most small businesses because its Free plan has no monthly fee, no contract and one flat rate for every major card. PayPal had the lowest flat in-person rate among those we could price, Stripe the lowest flat online rate, and Helcim suits a business that takes a lot of cards. Toast is built for restaurants and works only with its own POS.
How much does credit card processing cost?
Most providers charge a percentage plus a few cents on each sale, from 2.29% + 9¢ in person at PayPal to 3.09% + 15¢ at Toast's Pay-as-you-Go, and 2.9% + 30¢ online at Stripe. On $10,000 a month in sales of $60, the flat-rate providers we could price cost between $244 and $334 a month in person and between $340 and $444 online, hardware not included. Helcim and Stax add a margin to the card networks' own cost instead, which comes to $53 and $112 a month in person on the same sales, before the networks' share. Prices checked on October 14, 2026.
Which credit card processor has the lowest fees?
Among the providers we could price in full, on $10,000 a month in sales of $60, PayPal was the cheapest in person (about $244 a month, at 2.29% + 9¢), followed by Chase and Clover (about $277), Stripe (about $278) and Square (about $285). Online, Stripe was the cheapest (about $340), then Authorize.net ($365, including its $25 monthly fee), Square (about $380) and PayPal (about $381). Helcim's margin is $53 in person and $92 online, and Stax's $112 and $124, but the card networks' own cost comes on top, so we do not rank them on those figures. Chase's online rate (2.9% + 25¢) comes with a monthly fee shown only as "from $9.95", and Clover publishes no online rate, so we could not price either one online.
Which credit card processors have no monthly fee?
Square (Free plan), Stripe, PayPal and Helcim have no monthly fee. Toast's Pay-as-you-Go has none for the software, Clover's Starter plan is $0 with a $199 reader, and Chase's QuickAccept has none of its own but needs a Chase Business Complete Banking account, which costs $15 a month unless you meet a waiver rule. Stax charges $99 a month and Authorize.net $25.
Do I have to sign a contract for credit card processing?
Square, Helcim, Stripe and PayPal list no contract and no fee for leaving. Chase says its standard agreement is month to month with no cancellation fee, Stax asks for 30 days' notice, and Authorize.net says its gateway has no contract. Clover says its subscriptions are non-cancelable, and Toast's software comes with a 2 year agreement that renews yearly, so ask for the term and any early termination fee in writing.
What is the difference between flat-rate and interchange-plus pricing?
Every card payment has a wholesale cost set by the card networks, called interchange. A flat-rate provider folds that cost and its own margin into one percentage, so you always know the rate. An interchange-plus provider such as Helcim passes the wholesale cost to you at face value and adds a small published margin, so the total changes with the card used, a premium rewards card costing more than a debit card. Stax does the same with a monthly subscription in place of a percentage margin.
Do I need a merchant account?
A merchant account is the account that receives your card sales before they move to your bank. Some providers set one up for you behind the scenes, others open one in your business's name. Authorize.net's All-in-one plan includes one, while its Gateway only plan expects you to bring your own. Which kind a provider uses is in its terms, and it can change how holds and reserves work, so ask before you sign.
Can a credit card processor hold my money?
Square, Stripe, PayPal, Helcim, Stax and Toast each say they can hold or reserve part of your money if they see risk, for example when you take payment well before you deliver or when chargebacks rise. PayPal says it can hold a new seller's first payments for up to 21 days, and Stripe says a new account's first payout typically takes 7 to 14 days. Chase and Clover do not publish a reserve policy on the pages we read. Keep a cash buffer for your first weeks.
Why are Shopify Payments, Payment Depot and Fiserv not on this list?
We only list providers whose US prices we could read on their own pages. Shopify's pages showed euro prices and rates for another region when we checked, and it only works for Shopify stores. Payment Depot's website blocked our connection, so we could not read its fee schedule. Fiserv publishes no small-business processing rates: its small-business page is Clover's, which we do list.
