The Category Manager's Guide to Trapped Working Capital

Last updated July 2026

The short answer

To free working capital tied up in inventory, raise inventory turns and cut days sales of inventory (DSI) by removing excess and obsolete stock and right-sizing safety stock — without dropping fill rate. Maintained targets the exact SKUs holding cash hostage and protects service levels while it does.

What you're measured on

Speak in category savings, price variance, percent on-contract, and supplier performance.

  • Category savings
  • Supplier performance
  • % on-contract
  • Price variance

Where the value is

  • Raise inventory turns / cut DSI on the SKUs holding the most cash
  • Remove excess and obsolete stock that never sells
  • Right-size safety stock without dropping fill rate
  • Give finance one trustworthy view of inventory value and risk

The pains this removes

  • No benchmark for what a category should cost
  • Tail spend fragmented across suppliers
  • Slow quote cycles on tactical buys
  • Off-contract leakage in the category
