There are two account types: Advertiser and Organisation.
Advertiser accounts
Advertiser accounts are the most common account type. They're used to create and manage advertising campaigns. Multiple users can manage a single advertiser account, with three levels of access to control what each user can do.
Organisation accounts
Organisation accounts sit above advertiser accounts, giving you visibility and control across multiple advertisers in one place. They're ideal for:
Large organisations that want to keep advertiser accounts separate for easier management
Agencies managing campaigns across multiple clients
As an organisation user you can view all advertiser accounts under your organisation and set up a shared billing account. To learn more, read Set up organisation billing.
