Once you completed the checkout you can immediately use your Condens account. The credit card will be charged automatically based on the selected billing cycle and you will receive an email with the invoice to the provided email address.
If someone else completes the purchase for you, for example your manager or a colleague from accounting or IT Ops, you can invite them as a Non-Research Admin. With that role they can manage users and take care of billing without counting towards the number of used seats. Read more about user roles here.
