Charging Users for Disk Space
There are two approaches to charge customers for disk space. To avoid double billing, don't use both of them in the same plan.
- Charging for Increased Quotas
Set free units and recurrent prices for quotas. If end users need to upload more MB than free quota allows, they have to increase it.
- Charging for Increased and/or Exceeded Summary Disk Usage Limit
Enable the summary disk usage resource and set free units, recurrent and extra prices for it. Summary disk usage free units make up user's initial summary disk usage limit. If by the end of billing month user's average summary disk usage exceeds it, they will be charged usage (overlimit) fees. To prevent it, users can increase their summary disk usage limit (unless it is MAX restricted) and be charged recurrent fee for monthly resources which is usually less than usage (overlimit) fees.
Customers are not refunded if they haven't used up all the reserved disk space.
If customers reduce prepaid quotas or summary disk usage limit, they are refunded as described in Money Returns.
