Accounts on both the pay-as-you-go and Unlimited plans have the ability to create a Team Account. This allows the administrator to invite and remove users, and billing information is hidden from child accounts.
You can create a Team Account under your account on the dashboard. There is no additional cost for creating a Team Account.
Be aware that if you are on the pay-as-you-go plan, the free tier will split among all of the users on the account. For example, if you have a Team Account with five users total, each user will get 500 free lookups per day.
If you need to invite someone who has a pre-existing Geocodio account, they will need to delete their account first. Please have them download any needed information from their account and have them delete their account. You'll then be able to invite them to your team.
To change the administrator, you will need to change the email address associated with the current administrator's account to be the new administrator's email address.
If the email address you want to be the administrator already has a Geocodio account, that account will need to be deleted first. Log in to the account and delete it here. You can then log in to the current administrator account and change the email address.
