## Calculations for the Hosting Plan Change

If your customer upgrades his (or her) Hosting Plan to another one (or to the same one, but to the longer subscription period) then the following is taken into account:

- The period of time a customer have used the old Hosting Plan. For example, if a customer had subscribed for one month and had used a Hosting Plan during 5 days, then the amount for the unused subscription period will be refunded at the pro-rated price.
- The new Hosting Plan billing rates and whether the setup fee is charged or not. The new Order is being created, and (depending the setup fee settings) this Order includes the subscription fee for the new Hosting Plan and may either include the full setup fee for the new Hosting Plan or (if the new Hosting Plan setup fee is higher) the difference between the new Plan and the old Plan setup fees, or may not include the setup fee at all.

Summarizing, if a customer upgrades his (or her) Hosting Plan:

- A customer is refunded (the credit adjustment for unused subscription period is issued).
- The Order for the new Hosting Plan is created.
- After the Order is paid, the customer's subscription is changed: now it includes the new services and starts from the date of upgrade.
