Websites that include online shopping carts and automated ordering processes generally make use of payment gateways such as Authorize.Net, NMI, or eProcessing Network as a way to handle credit card processing. When making a purchase online, the transaction is ultimately going to a credit card processor but it needs to get there somehow.
The payment gateway provides an efficient, secure method to transport the data between that website, the credit card processor and the credit card issuers various systems. A payment gateway also allows you to simplify security by storing cardholder data on their servers, not yours. Even if you “do not store your clients’ info” you still need the ability to access all your clients’ accounts in the case of a refund request for example.
