Ad account is a feature of Facebook Ads that allows businesses to create, manage and track their Facebook ads. Businesses can create multiple ad accounts and control who has access to each one.

Business Manager is a tool developed by Facebook that allows businesses to manage their Facebook presence, including their ad accounts, pages, and people who work on them. It’s designed for businesses that need to manage multiple ad accounts or pages, and want to grant permissions to different people or agencies.

Getting access refers to the process of allowing someone to access an ad account or business manager. This can be done by adding them as a user and granting them specific permissions, such as the ability to create ads, manage billing, or view performance metrics.

In order to get access to an ad account or business manager, you typically need to be invited by someone who already has access. Once you receive an invitation, you can accept it and follow the steps to gain access. Alternatively, if you are the owner or administrator of the ad account or business manager, you can add users and assign roles and permissions as needed.

It’s important to manage access carefully and only grant permissions to people who need them, in order to ensure the security and privacy of your ad account and business data.
