A change to an account balance that reflects a discount or a refunded amount is called an adjustment. In billing and accounting, adjustments are used to modify what a customer owes or to record credits when something is returned or a discount is granted. This keeps the account accurate by formally updating the balance. For context, a rebate is typically a post-purchase incentive or credit issued after the sale, often as a separate payment or greating, not the standard term for a general balance change on an account. A deduction is a subtraction from a total in contexts like taxes or payroll and isn’t the general term for applying a discount or refund to an account. Allocation means distributing funds among different accounts or categories, which isn’t about reducing or crediting an amount due.
