CMMS vs EAM
A CMMS manages maintenance — work orders, PMs, spares. An EAM is broader, managing the whole asset lifecycle including procurement, finance and multi-site operations. Smaller maintenance teams usually need a CMMS; large asset-intensive enterprises lean to EAM.
What each one is
A CMMS (computerised maintenance management system) manages the maintenance function: the asset register, work orders, preventive-maintenance schedules, spare parts and maintenance history. An EAM (enterprise asset management) system does all of that and extends across the whole asset lifecycle — procurement, finance, depreciation, compliance and multi-site operations.
| CMMS | EAM | |
|---|---|---|
| Focus | Maintenance execution | Whole asset lifecycle |
| Scope | Work orders, PMs, spares | + procurement, finance, multi-site |
| Best for | Single/few sites, maintenance teams | Large, asset-intensive enterprises |
How to decide
The line blurs — many modern CMMS products have grown EAM-like features, and EAM suites include CMMS functionality. As a rule: if your need is to run maintenance well at one or a few sites, a CMMS is simpler, cheaper and faster to adopt. If you manage large, capital-intensive assets across many sites and need procurement, finance and compliance joined up, EAM fits. Start from the problem you actually have, not the bigger label.
Frequently asked questions
What is the difference between CMMS and EAM?
A CMMS manages the maintenance function — work orders, preventive schedules, spares and history. An EAM does all that and extends across the whole asset lifecycle, including procurement, finance, compliance and multi-site operations. EAM is broader; CMMS is focused on maintenance execution.
Do I need a CMMS or an EAM?
If you need to run maintenance well at one or a few sites, a CMMS is simpler, cheaper and faster to adopt. If you manage large, capital-intensive assets across many sites and need procurement, finance and compliance joined up, an EAM fits. Start from your actual problem.
Can a CMMS do what an EAM does?
Increasingly the line blurs — many modern CMMS products have added EAM-like features, and EAM suites include CMMS functionality. For maintenance-focused needs a CMMS is usually enough; for enterprise-wide asset, finance and procurement management an EAM is designed for it.

How to choose predictive maintenance software
Choose predictive maintenance software by starting from your critical assets and data, not the feature list: match the approach (sensor vs analytics) to those assets, check it integrates with your CMMS, insist on a clear pilot with a measurable target, and weigh total cost against failure cost.
