The Challenge

Most markdowns are reactive, not engineered.

Late Decisions

Discounts are decided late, based on "gut feel" and ageing stock reports rather than data.

Conflicting Objectives

Different teams push conflicting objectives: sales want volume, finance worries about margin.

Uniform Depth

Markdown depth is uniform across stores, channels, and customer segments.

Unclear Trade-offs

No clear view of the trade-off between clearing inventory and eroding brand and price integrity.

Result: excess stock lingers too long, then leaves in panic sales with deep margin cuts.

Business Outcomes

Markdown Optimization should deliver clear commercial gains.

Higher Margin

Reduce unnecessary discount depth while still hitting sell-through targets.

Faster Turn

Move ageing SKUs before they become stranded stock.

Lower Write-offs

Reduce end-of-season and end-of-life inventory losses.

Better Planning

Give merchandising and finance predictable clearance and margin outcomes.
