If you increase users: You will be charged a prorated amount adjusted for the new number of users for the remainder of the current billing period. Then, at the beginning of your next billing cycle, all users will be billed together at the full rate. Example: you have an annual account with 10 users and your account is renewed on January 1 of each year. If you add another 1 user on September 1, you will be billed $ 76.21 ($ 228 × 122/365 days) for that additional user for the remaining 4 months (122 days) of the year. Then, on January 1, all 11 users will be billed at their regular rate. If you reduce users: You will be credited a prorated amount for the number of users and the remainder of the current billing period. Then, at the beginning of your next billing cycle, all users will be billed together at the full rate, with their credit applied.
