Nice article covering some of the terms that are used related to point of sale systems - I'm guilty of often using acronyms so here are some additional terms not found in the original article:
SaaS: Software as a Service - software that you pay an ongoing fee to use (normally monthly but can be annual or even seasonal).
Partner: Company that is trained and certified to sell, install, train on, and support a specific point of sale software program.
POS: Point of Sale - a software program or app used to track sales, inventory, and customer information. Not to be confused with payment terminals or point of service hardware and software.
Merchant Services: any and all things related to how you accept and authorize payment by debit and credit cards, Apple Pay, and Google Wallet. This includes the hardware used as well as the company that provides your credit and debut card processing (like Heartland, First Data, Gravity, etc).
