Proration of invoices by sessions.

To prorate the invoice amount by the no. of sessions booked / no. of sessions attended do the following:

* from your admin console, please go to Billing&payments -> Invoice settings ->Turn on the option 'Calculate invoice based on sessions booked or attended' .

* And then from the dropdown below, please choose whether you need proration to be by no. sessions booked or the no. of sessions attended.

Example for proration by no. of sessions attended:

Enrolling a student to an English course with a fee amount of 200$ and 10 sessions (20$ per session).

But we are booking the student just for 9 classes.

Below is the student profile page showing the student's course and no. of bookings.

Below is the invoicing process.

* Click Add invoice.

* Select the item as course -> select the course -> select the fee option and click Prorate fee by sessions button.

* Then choose the start date and end date. 

* You will see below that the fee amount gets prorated by the no. of sessions booked in between the selected start date and end date( 9 sessions in the example). So the fee amount changes from 200$ to 180$ (20$ per session)

The same logic will be applied if you choose the setting as 'Prorate by no. of sessions booked'. Example below.

Example :- out of 10 classes, student attends only 8 classes.

So as you can see, while invoicing , the fee amount changes to 160$ (40$ were reduced from total amount of 200$, since the student did not attend two out of the 10 classes)

The invoice will show the start date, end date and the no. of sessions attended/booked accordingly.
