Selecting the right Computeriszed Maintenance Management System (CMMS) comes down to how well it protects equipment uptime and manages your maintenance workload. Traditional CMMS tools were built for fixed industrial plants. Modern operations need a mobile-first system that handles equipment spread across many customer sites, without forcing technicians through heavy desktop software.
This guide explains what a CMMS does, what separates a strong one from a basic one, and how FieldEx tracks assets, automates preventive maintenance, controls spare parts, and keeps compliance records in order. It also covers how to choose, so you can match a platform to how your maintenance work actually runs.

A Computerised Maintenance Management System is central software that simplifies maintenance work, extends asset life, and keeps equipment running. The key features usually include:
Organize equipment into multi-level hierarchies, log full service records, and keep the complete maintenance history for each machine.
Learn moreAutomate maintenance on a time-based schedule, or on a combined time-and-meter schedule, so services happen before equipment fails.
Learn moreCreate, assign, and close maintenance jobs while logging tasks, technician notes, and the spare parts used.
Learn moreFollow stock levels across warehouses, technician bins, and active jobs, so every part used is tied to a work order.
Learn moreManage recurring certifications, safety inspections, and audit records against the equipment they belong to.
Learn moreBuyers often ask whether they need a CMMS or Field Service Management (FSM) software. The honest answer for most operations is both, so it helps to know the difference.
A CMMS is built around the equipment. It exists to keep machines running, track their history, schedule their upkeep, and prove they were maintained. Its center of gravity is the asset.
If you only manage maintenance on your own fixed equipment, a CMMS alone may be enough. The moment you send people to different sites, you are doing field service too. FieldEx runs the CMMS and the FSM side in one platform, against the same assets, sites, and customers, so a scheduled service and a reactive repair on the same machine share one history.
Many legacy CMMS platforms fail because field technicians find them too heavy to use on site. What makes FieldEx such a strong CMMS is how it closes the gap between management visibility and daily field work by pairing a flexible CMMS engine with full FSM features. It handles any maintenance work type against any physical asset type in one place.
Track complex machinery down to the exact sub-component. FieldEx supports multi-level parent-child asset structures, so a technician can log a repair or part replacement against a sub-assembly while the parent asset keeps its overall service timeline. Because the engine is asset-agnostic, the same system tracks a generator, a vehicle, a chiller, or a coffee machine, without a separate template per type
Learn moreSet up preventive maintenance on a time-based schedule, or on a combined time-and-meter schedule where either the calendar or the usage meter can trigger the next job. You choose whether a service is driven by elapsed time, by runtime hours, kilometres, or cycles, or by both together. This suits everything from monthly filter changes to usage-based servicing on generators, pumps, and vehicles.
FieldEx also includes self-healing schedule logic. If a routine service becomes overdue past a threshold you set, the system reschedules the next visit based on when the work is actually completed, so the schedule does not build an artificial backlog of missed dates. Preventive maintenance can run against a single asset or a whole fleet.
Keep compliance separate from routine maintenance. FieldEx has a dedicated layer for recurring certifications and scheduled inspections, configured against each asset. Set the frequency once and the system generates the dated records for you. Add reminders before due dates, tie each inspection to a mandatory digital checklist the inspector must complete, and upload the official certificate or report straight onto the asset record. When the certificate is due again, the next record is already waiting.
Maintain granular stock control for audit and accounting. FieldEx tracks spare parts through a clear structure: Location (warehouse or depot) → Zone → Bin, including the personal bins that represent technician van stock. Parts then transfer onto the Job Order they are used on. Transfers move stock from bin to bin, to a technician's bin, or directly onto a job, so you always know where a part is and which work consumed it. This gives you a clean trail from stockroom to machine.
Find your high-failure equipment before it damages productivity. FieldEx calculates Mean Time Between Failures (MTBF) and Mean Time to Repair (MTTR) directly on each asset from real work order logs, alongside failure rate, downtime, total repair time, and utilization. For broader enterprise reporting, asset and job data feeds straight into Microsoft Power BI through built-in connectors.
Set up maintenance work in your own terms. Create custom work order types with their own status paths and field visibility, and control who can move a job into a given status, such as reserving an "Approved" sign-off for a supervisor. Field names, list values, and module labels can be renamed to match how your team already refers to its equipment and work, so people are not learning a new vocabulary to use the system.
Digital inspection checklists do more than record a pass or fail. Map individual answers so that a failed check automatically creates a corrective repair job on completion, using the template and task steps you set. One completed inspection can raise several corrective jobs if several answers are mapped, with no manual re-entry.
Learn moreTechnicians run maintenance from the Android and iOS apps. They open an asset and its history, complete inspection checklists, log parts used, capture photos, and collect sign-offs on site. Job-related asset information and record edits work offline and sync back once the technician is online again, so a service in a basement plant room or a remote site still gets recorded.
You do not have to navigate deployment alone or wait days for a reply. FieldEx guides your team through setup, workflow configuration, and technician training, and provides ongoing support. Onboarding and configuration come at no extra cost.
Use this as a checklist when comparing platforms:
Can it model parent-child equipment, so repairs on a sub-component still roll up to the parent's history?
Does it support time-based and combined time-and-meter schedules, and can it reschedule overdue services instead of stacking a backlog?
Can you manage recurring certificates and inspections separately from maintenance jobs, with reminders and document uploads on the asset record?
Can you track stock from warehouse to bin to job, with a clear trail of what each job consumed?
Can you set up recurring maintenance routines across flexible intervals – from daily and weekly checks to monthly and annual services – so routines run automatically according to operational needs?
Does it track the full history of a machine from initial purchase through leasing assignments, repair histories, contract details, and warranty status? Can it store manufacturer manuals directly on the asset record so technicians have instant access on site?
Can you scan a QR tag on a machine to open its record, and let non-users report faults through a public form?
Are MTBF, MTTR, downtime, and utilization tracked on the asset, and can the data feed Power BI?
Can technicians run maintenance on a phone, including partial offline work that syncs back?
Can you produce job sheets and service certificates in your own layout, with signatures and photo evidence?
The strongest CMMS is the one your technicians will actually use and the one that fits how your equipment is serviced.
Work through these before you commit:
If your equipment runs on usage rather than the calendar, you need meter-aware scheduling, not just fixed dates. If your machines have sub-components that fail independently, you need parent-child hierarchies. Match the asset model first.
If certifications and inspections carry legal or audit weight in your work, a system that treats them as a proper layer, with reminders and stored documents, saves you from tracking renewals in a spreadsheet.
A CMMS that only works well at a desk fails where maintenance happens. Test the mobile app the way a technician will use it, including with no signal, before you decide.
The value of a CMMS is the record it builds over time. If parts, jobs, and asset history live in separate places, you lose the reliability data that justifies the system. One connected record per asset is the point.
If you send people to customer sites, a CMMS alone leaves the dispatch and customer side unmanaged. A platform that covers both keeps maintenance and field work on the same records.
Do you need FSM?
