Maintenance, Repair & Operations (MRO) Procurement is often the forgotten stepchild of industrial purchasing. While direct materials receive meticulous attention from procurement teams, MRO spend—which can represent 5–15% of total operating costs—often goes unnoticed. The result? Hidden costs that silently erode margins.
1. Unauthorized Purchases
When service technicians bypass approved suppliers to buy parts directly, the company misses out on volume discounts, pays premium prices, and creates invoice chaos. Studies show that unauthorized purchases can inflate MRO costs by 15–25%.
Solution: Implement an e-catalog system (such as UNITEC) that makes finding approved parts faster than searching externally. When the right tool is easier to use, compliance follows naturally.
2. Emergency Requests
Rush orders for critical spare parts cost 3–5x more than planned purchases. Express shipping, overtime labor for receipt and pressure on the production line 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 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. Consolidating to 50–80 key suppliers through one outsourcing partner typically saves 12–18% on total MRO spend.
4. Inventory Maintenance Costs
Stored parts cost money: warehouse space, insurance, risk of obsolescence and tied-up working capital. Industry benchmarks suggest that carrying costs average around 20–30% of inventory value per year.
Solution: The ZeroCost® model eliminates inventory holding costs entirely by transferring ownership of inventory 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, re-orders 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 Final Result
These five hidden costs typically add 20–30% to what companies think they are spending on MRO. The good news: With the right procurement tools and strategy, most of these costs can be dramatically reduced. Contact our MRO experts for a free procurement audit.
