How to improve inventory management: a practical seven-step guide

Most organizations that want to improve inventory management are trying to do two things at once: hold less cash in stock and run out less often. Those goals only look contradictory when policies are vague and records are unreliable. The steps below follow the order we generally recommend, because each one depends on the one before it.

1. Make the records trustworthy

Optimization built on inaccurate data simply moves errors around. Run a sample count across a representative mix of items and locations, record the variance and, more importantly, its cause. Typical causes include receipts posted at the wrong time, unit-of-measure mismatches and unrecorded transfers.

2. Replace the annual count with cycle counting

Counting high-value and fast-moving items more frequently catches drift early and tells you why it happens. Use reason codes for every adjustment and review them regularly, so the counting routine improves the process rather than only correcting the numbers.

3. Segment the range

Not every item deserves the same attention. An ABC analysis ranks items by value or volume; an XYZ analysis adds demand variability. Combining the two gives each group a sensible policy instead of one rule for everything.

4. Set reorder points and safety stock deliberately

Reorder decisions should reflect actual demand, supplier lead times and the service level you want for each segment. Document the assumptions so they can be reviewed when demand or suppliers change.

• Measure lead times from real receipt data, not supplier quotes
• Set service targets per segment rather than one company-wide figure
• Review parameters on a fixed cycle, more often for volatile items

5. Tackle slow-moving and excess stock

Identify items with no movement over an agreed period and decide case by case: sell through, return, rework, transfer or write down. Then fix the upstream cause — usually ordering habits or minimum order quantities — so the problem does not return.

6. Align operations and finance

Inventory is both a physical and a financial asset. Agree how adjustments are approved, how inventory is valued and when it is reconciled to the ledger. A shared monthly reconciliation turns month-end from investigation into confirmation.

7. Monitor a small set of measures

A handful of measures — record accuracy, stock-outs or fill rate, inventory turns or days on hand, and excess or obsolete value — is usually enough. Review them in an existing meeting, with owners and agreed actions. Excel works to start; Power BI or Tableau connected to your ERP can follow when the measures have proved useful.

Where to begin

If you can only do one thing this quarter, start with record accuracy. Every later step depends on it. If you would like an outside view of where your inventory practices stand, our inventory management consulting service is designed to work through these steps with your team.
