What is a discount? E-commerce definition
June 4, 2026
A discount refers to a price reduction granted to a customer: percentage discount, fixed amount, free shipping, promo code, launch offer, or automatic discount. In e-commerce, discounts can stimulate conversion, trigger a purchase, or clear stock. However, they must be used with moderation, as they influence margins, perceived value, and buying habits.
Summary
Definition of discount
A discount is a temporary or conditional reduction of the initial price. It can be visible directly on the product detail page, applied in the cart, reserved for a promo code, or triggered automatically based on specific rules: minimum amount, specific collection, first order, or customer segment.
There are several forms of reduction. A 10% discount, a €15 rebate, a "buy 2, get 1 free" offer, a crossed-out price, or free shipping are all part of a discounting approach, even if their perceived effect on the customer differs.
Concept | Role |
|---|---|
Promo code | Discount entered by the customer at checkout. |
Automatic discount | Discount applied without customer action. |
Crossed-out price | Comparison between the old price and the discounted price. |
Free shipping | Financial benefit applied to shipping costs. |
A discount is not just a commercial mechanism. It is also a signal sent to the market: urgency, opportunity, clearance, loyalty, or launch.
Why discount is important in e-commerce
The discount can remove a barrier to purchase. A hesitant visitor may finalize their order if a time-limited advantage makes the decision easier. It can also encourage a higher shopping cart value when tied to a threshold, for example free shipping starting at €80.
Discounts also serve to liven up a commercial calendar: sales, Black Friday, launch, brand anniversary, end-of-series, or reactivation campaigns. They allow for creating a reason to buy when the product alone is not enough to trigger urgency.
But its repeated use can weaken the brand. If customers learn that a discount always comes after a few days, they may delay their purchases. A discount strategy must therefore protect the margin and perceived value.
Discount types and commercial effects
Not all discounts produce the same effect. A percentage discount seems attractive on low prices, while a fixed amount can be clearer on a high basket value. Free shipping acts on a very concrete barrier: the final cost at checkout.
Conditional discounts are often healthier than general markdowns. They can support the average order value, reward loyal customers, or target a specific collection without devaluing the entire catalog. The choice depends on the objective: converting, increasing AOV, clearing stock, or reactivating an audience.
Percentage discount for highly visible campaigns.
Fixed amount for high basket values.
Free shipping to reduce friction at checkout.
Discounts on Shopify
Shopify allows you to create discount codes and automatic discounts directly from the admin. Merchants can define the discount type, the eligible products, dates, eligibility conditions, usage limits, and targeted customers.
Discounts can apply to a product, a collection, an entire order, or shipping rates. Advanced features, apps, and Shopify Plus allow you to go further with more specific logic, such as stacked promotions, B2B offers, or complex cart rules.
Before launching a promotion, you must test the checkout. The code must work on the right products, reject the planned exclusions, and clearly display the amount saved.
Points of vigilance to be aware of
Discounting must be managed alongside the margin. A reduction that increases sales but destroys profitability is not a sustainable success. Payment, delivery, return, and acquisition costs must be taken into account before validating an operation.
Clarity is also essential. A code that does not work, a hidden condition, or a different promise between the advertisement and the checkout creates frustration. A good discount is simple to understand, easy to apply, and consistent with the brand strategy.
