Quick answer: MRO spend covers spare parts, consumables, tools, and small emergency purchases, usually bought from dozens of different suppliers with no shared naming convention. Because it's low value per transaction, it rarely gets the classification attention that bigger categories do, which is exactly why MRO spend is one of the most consistently under-managed lines in an FM budget.
Why MRO gets ignored
No single MRO transaction is big enough to trigger scrutiny. A £40 part here, a £120 tool there, spread across dozens of suppliers and hundreds of transactions a year. Individually, none of it looks worth the effort to review. Collectively, it's a real budget line that nobody manages as one.
Why low value doesn't mean low impact
Added up across a portfolio and a year, unclassified MRO spend is often larger than people expect, and because it's never been classified, nobody can say which suppliers, categories, or sites are driving it.
What classification unlocks even at this scale
Once MRO purchases are classified the same way regardless of supplier or site, you can finally see the shape of the spend, which categories dominate, which suppliers are used most, and where consolidating purchasing would actually save money.
Pearstop classifies MRO spend at the same level of detail as any bigger category, so the parts, tools, and consumables budget that usually gets ignored because it's low value per line finally gets managed as the real cost centre it actually is.
