Maintenance, repair and operations (MRO) is often the forgotten sector of industrial procurement. While direct materials receive meticulous attention from procurement teams, MRO spend—which can represent 5–15% of total operating costs—frequently spirals out of control. The result? Hidden costs that silently erode margins.
1. Maverick Purchasing
When maintenance technicians bypass approved suppliers to purchase parts directly, the company loses volume discounts, pays premium prices and creates invoice chaos. Studies show that maverick purchasing can increase MRO costs by 15–25%.
Solution: Implement an e-catalog system (such as the UNITEC) E-Catalog) that makes it faster to find approved spare parts than external searches. When the right tool is easier to use, compliance follows naturally.
2. Emergency Orders
Urgent orders for critical parts cost 3–5 times more than planned purchases. Express shipping, overtime receiving, and production line pressure all add up.
Solution: Predictive maintenance combined with intelligent inventory management reduces emergency orders by up to 60%. UNITEC's Virtual Warehouse model keeps critical spare parts available without tying up capital.
3. Proliferation of Suppliers
The average manufacturing plant works with 200–400 MRO suppliers. Each supplier means separate contracts, invoices, quality checks and relationship management. Consolidation to 50–80 key suppliers through one outsourcing partner typically delivers savings of 12–18% on total MRO spend.
4. Inventory Maintenance Costs
Spare parts stored on shelves cost money: warehouse space, insurance, risk of obsolescence and tied up working capital. Industry benchmarks suggest carrying costs are around 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 10,000+ manufacturers is complex and error-prone.
Solution: A comprehensive e-catalog with 500,000+ verified components and intelligent cross-referencing eliminates specification errors at the source.
The Conclusion
These five hidden costs typically add 20–30% to what companies plan to spend on MRO. The good news: with the right tools and a proper procurement strategy, most of these costs can be dramatically reduced. Contact our MRO specialists for a free procurement audit.
