Creating an account on CAASie is both free and easy to do. Fill in the required details in the sign up sheet. When you first sign up, you will create two entities: your user and your organisation. * **User:** This is you, as a person using CAASie. This is your personal login. * **Organisation:** The organisation is the face of your business on CAASie. This is the entity that manages campaigns. Multiple users can be added to an organisation; no need for a shared login. ### Which CAASie account should you choose? There are two account types available: Advertiser and Agency. * **Advertiser:** For businesses that represent themselves. * **Agency:** For businesses that represent multiple clients or branches. You can read more about the differences [here](/getting-started/account-creation/agency-vs-advertiser.md). Make sure to read CAASie's [Agency Representation Agreement.](broken://pages/Tf9RrivLHRwJoyTrsqhQ) If you accidentally sign up for the wrong account type, please let CAASie’s support team know at so your account can be converted to the correct type. ### What do I name my organisation? The name of your organisation should be your business's trading name. If your business name and advertised brand do not match, your artwork will be rejected as a potential fraud risk. To manage multiple brands under one business on CAASie, make sure to sign up for an agency account to keep the identities, campaigns and billing information organised. ### How do you share CAASie with others? To add colleagues to your organisation, you simply need to invite them via email. You can read more about that [here](/getting-started/account-creation/collaboration-and-teams.md). To share campaign information with a client, you can use this [guide](/account-management/share-with-clients.md).
