How can I add changes to the existing cycle?

You have the option to make the desired changes immediately or for the upcoming cycle.  If you choose to modify the contract immediately, you will receive an invoice directly for the additional (partial) amount until the next regular renewal, along with the additional accesses/licenses. The total amount for the new overall package will be calculated in the next regular invoice.

You change between the tabs to choose when the change shall take effect. 

Choose "Change immediately" or "Change with next cycle" to proceed with the wished changes.
