# Common Terms We Use

The platform and our support uses several advertising related terms that may be new for some advertisers. This guide explains all the important terms in simple language so you can understand everything clearly while using your ad accounts.

### **1. BM (Business Manager) - Meta**
A **Business Manager** is Meta’s central tool that stores your Pages, Pixels, Ad Accounts, Domains, Catalogs, and team access.
* BM is where your ad account will be assigned.
* You must accept the BM invite to access your ad account.
