Promotion Engine
A promotion engine is the part of an ecommerce platform that creates, applies and controls discounts and offers. It decides which promotions a basket qualifies for, such as percentage discounts, multi-buy deals or coupons, and calculates the correct price at checkout according to the rules the retailer has set.
Why it matters
Promotions drive traffic and average order value, but errors are costly: a missed discount frustrates customers, and an unintended stack of offers erodes margin. A dependable promotion engine lets marketing teams launch campaigns quickly while keeping pricing under control, and gives finance a clear record of what each campaign cost and returned.
