Billable Hours: Billable Hours are the total number of hours that are to be billed. If a child has a paid schedule or a prepaid-hours package, then those hours are subtracted from the Total Hours to calculate Billable Hours.

For example, a child is enrolled in an AM preschool program with scheduled hours from 9 am to 12 pm. And, the child attends from 9 am to 1 pm. Then the Total Hours for that day are 4 and the Billable Hours are 1.

Rate: Rate is the hourly amount that is multiplied with the Billable Hours to calculate the amount to be charged.

Rate is calculated from Default Bills of the program children are enrolled in and has attendance entries for.
