MRO (Maintenance, Repair & Operations)
Also known as: MRO, Maintenance repair and operations
MRO refers to the goods and supplies used to keep an organisation's equipment and facilities running — maintenance parts, repair items, tools, safety and consumables.
MRO covers everything needed to operate and maintain, rather than to produce: spare parts, lubricants, hand and power tools, cleaning supplies, personal protective equipment and general consumables. It is a classic indirect category — high in transaction volume, spread across many small suppliers, and prone to unplanned, urgent buying.
Because MRO is fragmented and often urgent, it benefits strongly from consolidation onto a managed catalogue: fewer suppliers, contracted pricing, and reliable availability so maintenance is not delayed waiting on parts.
Frequently asked questions
- What is MRO in procurement?
- MRO stands for maintenance, repair and operations — the parts, tools, safety gear and consumables used to keep equipment and facilities running, as opposed to materials that go into products.
- Why is MRO spend challenging?
- It is high-volume, fragmented across many suppliers and often urgent, which makes it hard to control and a common source of tail and maverick spend.
