AI USE CASE
ML-Driven Markdown Timing Optimization
Optimize end-of-season markdowns with ML to maximize clearance revenue and minimize excess inventory.
What it is
This use case applies machine learning and optimization algorithms to determine the ideal timing, depth, and sequencing of markdowns for end-of-season and clearance inventory. By analysing sell-through rates, demand elasticity, competitor pricing, and remaining shelf life, the model recommends data-driven discount actions that clear stock before deadlines while protecting margin. Most mid-size retailers see payback within one to two seasons after deployment.
Data you need
Historical sales data by SKU, inventory levels, pricing history, sell-through rates, and ideally competitor pricing feeds covering at least two to three prior seasons.
Required systems
- erp
- ecommerce platform
Why it works
- Clean, granular historical sales and inventory data spanning at least three comparable seasons.
- Clear governance model defining when merchants can override the system and how overrides are logged for retraining.
- Pilot on one category or store cluster first to build internal trust before full rollout.
- Close collaboration between data science and merchandising teams to encode business constraints (minimum margin floors, brand protection rules).
How this goes wrong
- Model trained on atypical seasons (e.g. COVID) produces systematically biased markdown recommendations.
- Merchant teams override recommendations too frequently, negating model value and creating feedback loop gaps.
- Insufficient SKU-level sales history for long-tail items leads to poor demand elasticity estimates.
- Integration delays with ERP or POS systems mean recommendations arrive too late to action in-season.
When NOT to do this
Do not deploy markdown optimization if your inventory data is updated only weekly or your ERP cannot push price changes to stores within 24 hours, the model's time-sensitive recommendations will be wasted.
