We need to add more people to our team. How will that be billed?

Team:
 
You can add more people to your team at any time here. If you’re adding people above the number of users paid for, you will see a prorated charge. It will be included in your next receipt if you are on a monthly plan. It will be processed on the day new people are added (and a receipt will be sent to your team’s billing contact) if you are on an annual plan. If you’ve paid for a user that you have not assigned to a specific individual and you add a new individual to the team account, we won’t charge you for that person. You will just assign them one of the “empty” user spots on your account.
