Once the account is created, you will be prompted with the new organization screen.
If your organization already exists, ask the organization Admin to invite the e-mail you used to create your account in the organization.
Please note that an account can have multiple organizations, which you can access (or create a new one) by clicking on the badge in the top right corner of the interface.
To create a new organization, fill in the necessary fields. Only the name is mandatory.
Then, your organization will be created and you will be prompted with the screen listing locations, inviting you to create a new one for the organization. Once you have a location, you can invite other users to the organization to share the management of the locations and sites they contain.
