Practical, plain-English explanations of payment processing fundamentals — written for merchants, not engineers.
A payment processor is a company that manages the technical and financial steps required to move money from a customer's bank to a merchant's bank when a card transaction occurs. Every time a customer swipes, taps, or enters a card number online, a payment processor is working in the background — handling authorization, routing, settlement, and funding.
Merchant account and payment gateway are two of the most commonly confused terms in payment processing. They serve different roles — and understanding what each does helps you evaluate what your business actually needs and what you're already paying for.
The pricing model you choose for payment processing has a direct impact on your total cost — often more than the specific rate you negotiate. Understanding flat-rate, interchange-plus, and membership pricing helps you make a more informed comparison between processors.
Most merchants only see a single number on their monthly processing statement — but that rate is actually made up of multiple fee layers from different parties. Understanding how payment processing fees work helps you evaluate costs accurately and ask better questions when comparing processors.
Choosing a payment processor is a significant business decision — and most providers require a sales conversation before showing you actual pricing. A structured comparison framework helps you ask the right questions, evaluate options consistently, and avoid common mistakes.
