What is a discount in business?

Definition

A discount is a reduction applied to the full price of a good or service. A business gives discounts to its customers, for example in a sale, for buying in quantity or for paying early, and receives them from suppliers. When a product's price is cut for a promotion or sale, the discount is also called a mark-down.

Discounts come in different forms, and the books need to show each one clearly. A discount agreed before the sale, such as a quantity discount, is usually shown on the invoice as the full price less the discount, so the amount owed is the reduced figure. An early payment discount is different, because whether it applies depends on when the customer pays, so the difference between the invoice and the amount received also needs to be recorded. Which accounts these go to is a question for your accountant.

Keeping discounts visible, rather than simply entering a lower price, shows how much the business gives away in discounts over a month or a year. That figure matters, because a discount comes straight off the margin on each sale.

In Australia

business.gov.au's glossary describes a discount as a cut to the full price of a good or service, and gives a cut made during a sale or promotion its own name, a mark-down. Its pricing guide gives attracting new customers, selling unwanted stock and encouraging repeat business as reasons to discount, names special offers, bundles, quantity discounts, value-add offers and seasonal sales as common kinds, and warns that discounts can affect the bottom line. It suggests planning how and when to use them so they still cover your costs.

Its guidance on improving cash flow suggests encouraging upfront or early payment with discounts, and its guide to managing cash flow mentions committing to regular orders to get a bulk discount from a supplier. On displaying prices, the pricing guide says price comparisons, including was and now prices, must be truthful, clear and not misleading.

Common mistakes

  • Typing a lower price over the full price, so the books never show how much was given away in discounts.
  • Leaving an early payment discount unrecorded, so the customer's account shows a small balance that will never be paid.
  • Offering discounts without checking that the reduced price still covers the cost of the sale.
