discountsApplied

DiscountsApplied is a term used in transaction processing to record the discounts that have been applied to a sale or order. In e-commerce, point-of-sale systems, and accounting software, it serves as a record of reductions to the nominal price and is often used to compute the final total and to generate receipts or audit trails.

In data models, discountsApplied can be stored as a single numeric value representing the total discount amount, or as a structured collection of discount entries. Each entry may include fields such as id, type (percentage or fixed amount), amount or percentage, code or source, description, date applied, and scope (line item or whole order). The distinction between line-item discounts and order-level discounts is common, with line-item discounts reducing item subtotals and order-level discounts reducing the cart subtotal after line discounts.

Usage considerations: discountsApplied influences the calculation of the final price, tax base, and payment totals. In many jurisdictions, tax is calculated on the price after discounts; in others, some discounts are tax-excluded. The field supports analytics and auditing by enabling reporting on discount usage, promo code effectiveness, and revenue impact. For API design, it is common to expose discountsApplied as both a numeric total and a detailed list, allowing clients to display a receipt summary and to validate discount integrity.

Example: Subtotal 120.00, discount entries include a fixed 15.00 promo and a 10% item-level discount of 12.00, resulting in discountsApplied = 27.00 and a final total of 93.00.
