Service Module Fields in Service Plan
Any existing or new services you create to manage backup billing must be configured with 'Post Renew' set to 'Yes'.
Looking at the service, there are some custom data fields automatically created when the Backup Billing service module was enabled.
Billing Method
Included
Overage Rate
and
Associated Devices
The Billing Method field determines how you will want Ubersmith to calculate the overage billing. Disk Hours will bill for the actual GB-hours used, so if the client is using 1GB of backup space, they would be billed for 1GB X 30 days X 24 hours, for about 720 GB-hours of usage.
Average Usage bills according to the average over the period, so using the same case, the usage figure would be 1 GB. You can also think of this as charging by GB/month.
95th Percentile is another way of coming up with an average of usage during the month, and pricing is still per GB-month.
Disk Hours is slightly more accurate because it takes into account the varying number of hours month-to-month, but in general calculating Average Usage at $7.20 per GB is the same as Disk Hours at $0.01 per GB-hour.
The Included field determines how much usage the client is permitted for a given billing period.
The Overage Rate determines the dollar amount per unit they will be charged for going over their included allocation.
The Associated Devices field is optional - Ubersmith calculates the usage for any devices associated with the service.
Once you've configured these fields, Ubersmith displays a chart showing the usage calculated over the current billing period for the service plan. If an overage is calculated at the time of renewal, Ubersmith will bill for the overage amount due
