Discounts and Credits are considered two different types of concessions given to charges in SiteLink.
Discounts are always applied before tax (which affects the amount of tax that is calculated for the charge) and can only be applied at the same time a charge is created. Common examples of discounts include applying a special during a Move-In or giving a percentage discount for a prepayment of several months.
Credits are always applied after tax and can only be applied to existing charges. Common examples of issuing a credit include waiving a Late Fee and writing off charges as Bad Debt.
Discounts can be tracked in reports by the Discounts and Discount Summary reports.
Credits are tracked through the Credits Issued report.
