Context

Clearance planning has evolved into a strategic lever for large retailers, especially in the grocery and general merchandise space. Businesses managing high inventory volumes, seasonal shifts, and continuous product introductions need to optimize markdown and seasonal inventory decisions. Doing so can significantly impact both revenue and margins.

Many retailers still rely on tiered, time-bound discounting models. These overlook regional demand variations and product-level performance. Such rigid markdown approaches often lead to missed opportunities to recover value from unsold inventory. They also cause inconsistent execution across store locations and excess margin leakage. For multinational retailers operating at scale, building more responsive, data-driven clearance frameworks is essential to maintain agility and protect profitability.

Problem statement

The client, a Europe-based multinational grocery and general merchandise retailer, was facing persistent challenges in managing its clearance strategy. Depending on the store and product category, the goals of markdowns varied. Some locations required aggressive inventory reduction due to demand planning inaccuracies, while others focused on maximizing recovered revenue from unsold stock. The existing markdown process followed rigid, tiered discounting rules over predefined time windows, with triggers based primarily on product sell-through rates. While this approach offered structure, it lacked the flexibility to adapt to local demand shifts, assortment variations, and seasonal lifecycle timelines. As a result, the client experienced prolonged markdown cycles, reduced revenue recovery, and unnecessary margin erosion. 

To address these challenges, the client partnered with MathCo to design a dynamic, data-driven markdown optimization solution. The objective was to enable localized pricing, support scenario planning, and align clearance decisions more closely with real-time business needs. 

Impact

  • A ~3x increase in recovered revenue through dynamic pricing at the product-store level  
  • Achieved a ~8% increase in profit margins and successfully adhered to the required clearance timeframes 
  • Reduced excess inventory holding costs by ~$750K annually by accelerating sell-through of slow-moving SKUs
