How Discounts, Fees, and Taxes Work

Discounts, fees, and taxes modify the amount billed according to defined eligibility, charge, and tax rules.

These are different types of adjustments. Discounts reduce the price, fees add a charge, and taxes apply the tax rules required for the transaction. Keeping them separate makes the final amount easier to explain.

• Discount: reduces the normal price under an approved rule, code, agreement, or eligibility condition.
• Fee: adds a separate charge for a service, condition, or transaction.
• Tax: applies a tax amount or rate based on the relevant tax rules and jurisdiction.

Define who can receive a discount, when a fee applies, whether a fee is taxable, which tax rules or jurisdictions apply, and who is allowed to override an amount.

Separate records make it easier to explain the final price, review overrides, correct mistakes, report tax, and see whether a change came from pricing, a fee, or a tax rule.
