How are we billed when adding a new location in between billing dates?

If you want to add a new location in between billing dates, and you don't have any pre-paid locations available, then you will be prorated at the time you add the new location. The full price (monthly or yearly) for the new location will be added on the next billing date for the next billing period. You can add a new location at anytime by going to https://webcorp.com/console/organization/locations/add/ and completing the form.
