We get that, it happens. That’s why we offer tiered pricing to account for that variability. Your plan comes down to the starting moment of the competition: when you click “send” on your judge invitations, that locks in the number of competitors and the number of judges. Whoever is in the system in that moment counts.

If your quote doesn't match your start time numbers, we'll adjust your quote. If you've already paid, we'll either send you a refund or an additional bill.
