If you exceed the currently purchased number of users, you would need to buy additional user subscription for the excess. In case you exceed this somewhere in the middle of your subscription, you may purchase additional user subscription and we will charge you on a pro-rata basis to the end of the subscription.
E.g. You start with 50 users in January and you pay for 50 users upto December. Subscription is for 1 year. In July if you need an additional 50 users, you will pay only for 6 months for these additional 50 users on a prorate basis. In January next, the subscription is renewed for a total of 100 users. We follow this scheme to allow you purchase only when you need and pay for only what you use. Additionally it helps to manage the billing cycle more easily.
