Background
Gratis is one of Turkey’s largest and fastest-growing beauty and personal care retailers, operating more than 650 stores nationwide. Its expansive portfolio includes cosmetics, skincare, hair care and personal care products, with a strong emphasis on private label and exclusive brands. Promotions are at the core of Gratis’ growth strategy, with over 2,000 SKUs often on promotion across its stores and online at any given time. As a result, inventory planning and execution are critical to maintaining customer satisfaction and protecting revenue.

Challenge
Gratis’ rapid expansion—scaling from 250 to over 650 stores—required a fresh approach to inventory management. With a highly promotional model and complex supply chain involving more than 100 suppliers, the business needed a solution that could dynamically balance availability and efficiency. Their main priorities were reducing lost sales due to out-of-stocks and controlling excess inventory that strained resources. In addition, long lead times (up to 8 months for some products) made forecasting even more challenging. To maintain high service levels and deliver on customer expectations, Gratis needed more reliable, responsive inventory planning.
