How to purchase additional seats

If halfway into your billing period you need to add a new user and don’t have any available seats, you will be required to purchase additional seats at a prorated amount until the end of your current billing period.

To purchase additional seats:
  1. Go to
  2. Log in with your Atto account as the account owner
  3. Click on "Purchase Seats"
  4. Enter the number of seats needed
  5. Click on "Complete Purchase"

The charge will then be processed and seats will be added to your account. You can choose to invite new team members immediately or use the new seats later.

NOTE: If you've already sent an invite and don't have any available seats, the invite to the new users will not be sent until you’ve purchased the additional seats.
At the beginning of your new billing period, we’ll automatically update your subscription based on the number of active users in your account. Unused seats will be automatically removed.
