As soon as merchants make up their mind for selling their products or proffering their services, they are liable to quest the best way of payment processing for their respective businesses. Disarray and frustration are bound to accompany throughout the process unless you understand the difference between payment processor, payment gateway, and merchant account.
@margret How would you quickly distinguish the difference between payment processors, payment gateways, and merchant accounts - to someone who was curious on a surface level? And what search would you recommend that someone perform to learn more details on each?
