How AI-Powered Promotion Software Helped an Apparel Retailer Improve Sell-Through and Maximize Promo ROI

THE RESULTS

“Promotions are central to our revenue, but we lacked clarity on what was actually working. Promo AI brought structure to what to discount, by how much, and when, while balancing margin and sell-through.

– Head of Merchandising, Apparel Retailer

The Background

A fast-growing apparel retailer with a diverse assortment spanning dresses, seasonal collections, and everyday fashion relied heavily on promotions to drive revenue. With frequent campaigns across categories and constant pressure to clear seasonal inventory, the brand needed a smarter, more structured approach to promotions, one that could balance sell-through with profitability while reducing manual effort.

Industry: Apparel Retail
