Our Methodology

To help you find the right Credit Card Processing, we researched and analyzed dozens of options. Here is a roundup of our 2018 best picks for Credit Card Processing and an explanation of how we chose them.

Locating the Best Services

To find the best credit card processors for small businesses, we started by asking business owners which credit card payment processing companies they use or have worked with. We also asked what the businesses liked and disliked about these vendors, and whether they would recommend them to other small businesses and why.

Choosing the Best Services

Next, we created a comprehensive list of credit card processors suitable for small businesses. In addition to those mentioned by the small business owners we spoke to, the processors we were familiar with and those that contacted us asking to be considered, we also looked at credit card processing companies that appeared on reputable online sources, such as merchant services review sites and business websites.

Researching Each Service

We then researched these vendors and narrowed our list down based on different use-case scenarios (Best Picks categories above). Our research consisted of reviewing each processor's website, watching videos, reading how-to guides, browsing help resources, and trying out demos when available. We also posed as business owners and asked questions of sales and customer-support reps, to get a better idea of the quality of service and find out information that isn't readily available online.

Our Best Picks

In total, we compiled a list of more than 85 credit card processors. Our picks for top credit card processing companies are First Data, Flagship Merchant Services, Helcim, PayPal, Square and Stripe. Those that made it to our shortlist include Braintree, Chase Merchant Services, Dharma Merchant Services, Elavon, EMSplus, Fattmerchant, Global Payments, Payline, QuickBooks Payments, Shopify Payments, SumUp, TSYS and Worldpay, Inc.
