Maintenance, repair and operations (MRO) is often the forgotten area of industrial purchasing. While direct materials receive meticulous attention from purchasing teams, MRO spending—which can represent 5–15% of total operational costs—often goes unnoticed. The result? Hidden costs that silently erode margins.
1. Uncontrolled Purchases
When maintenance technicians bypass approved suppliers to purchase parts directly, the company misses out on volume discounts, pays premium prices, and creates invoice chaos. Studies show that uncontrolled purchasing can inflate MRO costs by 15–25%.
Solution: Implement an e-catalog system (such as UNITEC E-Catalog) that makes it faster to find approved parts than to search externally. When the right tool is easier to use, compliance comes naturally.
2. Emergency Orders
Urgent orders for critical spare parts cost 3–5 times more than planned purchases. Express shipping, overtime receiving work, and production line pressure add up quickly.
Solution: Predictive maintenance combined with intelligent inventory management reduces emergency orders by up to 60%. UNITEC's Virtual Warehouse model keeps critical parts available without tying up capital.
3. Supplier Proliferation
The average manufacturing plant works with 200–400 MRO suppliers. Each supplier means separate contracts, invoices, quality checks and relationship management. Consolidating to 50–80 key suppliers through one outsourcing partner typically saves 12–18% of total MRO spend.
4. Inventory Holding Costs
Parts on shelves cost money: warehouse space, insurance, risk of obsolescence, and tied up working capital. Industry benchmarks suggest that holding costs range between 20–30% of inventory value per year.
Solution: The ZeroCost® model completely eliminates inventory holding costs by transferring ownership of the stock to the supplier while maintaining availability guarantees.
5. Specification Errors
Ordering the wrong part—wrong voltage, wrong thread pitch, wrong material grade—wastes time and money on returns, reorders, and production delays. Cross-referencing between more than 10,000 manufacturers is complex and error-prone.
Solution: A comprehensive e-catalog with more than 500,000 verified components and intelligent cross-references eliminates specification errors at the source.
The Conclusion
These five hidden costs typically add 20–30% to what companies believe they are spending on MRO. The good news: With the right tools and a purchasing strategy, most of these costs can be reduced dramatically. Contact our MRO specialists for a free purchasing audit.
