How the discount is expressed
Discounts are held in basis points — hundredths of a percent.
Basis points exist so a discount like 7.5% is exact rather than a repeating decimal, which keeps a discounted bill and its payments in agreement to the pesewa.
What a discount actually touches
That is the intended behaviour: it is how you stop a scholarship from silently absorbing an examination fee you have to remit to GES. But it does mean a “100%” category rarely produces a zero bill, and parents will ask why. The answer is on the invoice, which names every line. See Fee items for setting the flag.Assigning a pupil to a category
A fee category is attached to a pupil’s enrolment for a term, not to the pupil record itself. One category per pupil per term. This matters at promotion: a concession does not follow a pupil into the next term on its own. When you promote a class you carry the category forward deliberately, which is your yearly opportunity to review it — see Closing the term. You can list every pupil currently on a given category, which is the check to run before billing: it is much easier to spot a pupil who should not be on the staff rate here than to find the discount later on an issued invoice.Changing a discount
Editing a category changes what future billing runs calculate. Invoices already issued keep the discount they were issued with, because an issued invoice does not change. To apply a newly agreed concession to a bill that has already gone out, issue a credit note instead.Who can edit it
Theedit_finances permission. Larger concessions can be put behind approve_waivers so that a discount is agreed by someone other than the person entering it.
