A volume discount is a price reduction offered when purchase volume exceeds defined thresholds. It can be applied at invoice (front-end discount) or settled retrospectively as a volume rebate.
Front-end versus back-end volume discounts
A front-end volume discount reduces each invoice as thresholds are crossed. A back-end volume rebate calculates the earned discount at period-end. Both achieve similar effective pricing; the operational, tax, and cash-flow implications differ.
Where visibility matters
Whether front-end or back-end, volume discounts create a specific need for threshold tracking - so the buyer knows when a purchase is about to unlock a better price, and the seller knows how to set expectations for accrual purposes.
