5 Ways to Reduce MRO Inventory Costs Without Risking Downtime
SKU rationalisation, vendor consolidation and safety-stock strategies for maintenance stores.
MRO stock (maintenance, repair and operations spares) ties up cash, but running short stops production. The aim is not the smallest stock; it is the right stock. These five steps cut cost without raising the risk of downtime.
1. Rank spares by criticality
For each spare, ask what happens if it is missing. Parts whose absence stops a critical line, and that take weeks to get, deserve stock. Items that are available next day and whose absence causes no stoppage need little or none.
2. Clean up the item list
Merge duplicate entries, such as the same bearing under two descriptions, and standardise on common sizes and brands where the application allows. A smaller, cleaner list is cheaper to hold and easier to reorder.
3. Set minimum and reorder levels
Base reorder points on how fast you use the item and how long the supplier takes to deliver. Review them when usage or lead time changes. Items that have not moved for a long time should be reviewed for removal.
4. Agree supply terms with your supplier
A supplier who can deliver quickly and keeps stock of common items lets you hold less yourself. Agree lead times, rate contracts or scheduled deliveries for regular items.
5. Track what you use and share the data
Record issues against machines. Patterns show which parts fail often, so you can fix the cause, and which are never used, so you can stop buying them. Keep storage organised and labelled so nothing is bought twice.
Key Takeaways
- Stock by criticality and lead time, not by habit.
- Reduce duplicates and standardise sizes.
- Use a reliable supplier to hold part of the stock for you.
