This guide compares ten widely used payment processing companies in the USA so you can match one to your business.

What payment processing companies do

A payment processor sends card data to the card networks and issuing banks, receives the approval or decline, and settles the funds to your account. A payment gateway is the checkout layer that captures and encrypts payment data, while a merchant account holds your funds before they reach your bank. Many providers bundle all three, while others handle only part of the chain. Read more in our guide to how a payment gateway works.

Payment processing pricing models

● Flat rate: One rate covers all costs. It is simple, but can cost more at high volume.
● Interchange-plus: You see the card network cost on each sale plus a fixed markup. It is more transparent but less predictable.
● Quote-based: Pricing is negotiated, common for enterprise.

A common benchmark is about 2.9% plus 30 cents for online transactions. On a $100 sale that is $3.20.

How to choose the right payment processing company

1. Match your sales channel. Online only, in-person or both.
2. Check platform support. Make sure it works with your cart, POS or CMS.
3. Model total cost. Include monthly, PCI, chargeback, international and refund fees.
4. Check payout speed and holds.
5. Review support hours, hardware terms and contract length.
6. Plan for growth. Look at multi-currency support and volume pricing.

Common mistakes

● Choosing on headline rate alone
● Ignoring refund and chargeback costs
● Missing early termination, PCI and statement fees in the contract
● Buying through a reseller without getting the rate in writing
● Locking into a contract before testing
● Overlooking account-hold policies for new accounts

Need a processor for a high-risk business?

Mainstream processors can decline or restrict some industries. In that case, review high-risk merchant account providers built for stricter underwriting.

Verdict

There is no single best payment processing company. Flat-rate platforms suit simplicity and lower volume, interchange-plus options suit scale, and enterprise providers suit global operations. Shortlist two or three, request written fee schedules, and compare total monthly cost.
