A CMMS is software that runs maintenance. It keeps a record of every maintainable asset, the work planned and done on it, who did it, what it cost and what parts were used. It replaces whiteboards, paper job cards and spreadsheets with a single system that schedules work, tracks it to completion and turns the history into decisions.
Core CMMS capabilities
| Capability | What it does |
|---|---|
| Asset records | The equipment list, with location, specs, manuals and history |
| Work orders | Request, assign, track and close jobs with time, cost and parts |
| Preventive maintenance | Recurring schedules by time or usage, and due lists |
| Parts & inventory | Spare parts stock, usage per job, reorder points (in many CMMS) |
| Calibration & compliance | Due dates, certificates and inspection records |
| Mobile | Technicians receive and complete jobs on a phone or tablet |
| Reporting | Backlog, PM compliance, MTBF, MTTR, cost per asset, downtime |
CMMS vs EAM vs asset tracking
The lines blur, but broadly: a CMMS focuses on maintenance execution. An EAM (enterprise asset management) system covers the whole asset lifecycle — planning, procurement, maintenance, finance and disposal — usually for large, asset-intensive organizations. Asset tracking software focuses on identity, location and custody. Many organizations need a bit of each, which is why modern platforms combine the register, tagging, maintenance and depreciation.
Why use a CMMS?
- Nothing falls through the cracks — every request becomes a tracked work order.
- PM actually happens — schedules produce due lists rather than relying on memory.
- History is kept — anyone can see what was done to an asset and when.
- Better decisions — cost-to-date and failure history inform repair-vs-replace.
- Compliance evidence — inspection and calibration records on demand.
What to look for
- A solid asset register underneath — maintenance is only as good as the asset data.
- Quick asset identification in the field (QR, NFC or RFID) so jobs are logged against the right item.
- Simple work orders technicians will actually complete on mobile.
- PM scheduling that fits how your equipment wears (time and/or usage).
- Reporting on the KPIs you care about.
- Integration options (API, exports) for finance and other systems.
Implementing a CMMS
The most common failure is starting with the software instead of the data. Clean up and tag the asset list first, agree criticality, load PM tasks for the most critical assets, and get technicians using work orders for everything — even small jobs — so the history becomes trustworthy. Add KPIs once there is enough data to mean something.
Asetavo as a CMMS
Asetavo includes CMMS capabilities on the Business plan, built on top of its asset register: work orders with status, assignee, cost and parts; recurring preventive-maintenance schedules with due lists; calibration records with due tracking; and the full service history on each asset's Asset 360 profile. Because assets are tagged, technicians can scan to find the right equipment and its history.
