Maintenance software: what it is and what it isn't
How a CMMS differs from an ERP, a helpdesk, a facility management tool or a spreadsheet, and when each one is actually needed.

Many conversations that start with “we need maintenance software” end up discovering that people were comparing entirely different categories. An ERP, a ticketing system, a facility management tool and a CMMS solve things that overlap just enough to cause confusion.
This article is about those boundaries, because choosing the wrong category is more expensive than choosing the wrong product within the right one.
What a CMMS does
A CMMS revolves around the asset: the equipment installed, not the item purchased. Its job is to sustain four things that no other system covers well:
- The asset record as a history: where it is, what model it is, what has been done to it, what anomalies remain open, how much it has cost so far.
- The periodicity: generating only the checks for two hundred pieces of equipment, checking whether the day is a holiday and whether the technician is available.
- Fieldwork: recording the intervention where it happens, even without coverage.
- The proof: what was checked, with what values, who signed off and when.
Everything else it does — warehouse, purchasing, quotes, customer portal — serves that purpose.
CMMS vs. ERP
The most common confusion, and the easiest to resolve: they don’t compete.
An ERP handles accounting, invoicing, purchasing, inventory and production. That’s where the customer master, the item master and pricing should live. What it doesn’t handle is the technical work on equipment, and not by oversight: it simply isn’t its subject matter.
The rule that avoids almost every problem is agreed on before connecting anything: the ERP owns customers, items and pricing; the CMMS owns assets, interventions and consumption. Each piece of data has a single place where it’s created.
Once that’s clear, integration is a technical matter. The integrations catalog details the scope of each connector, which isn’t the same for all of them, and there’s more on how to approach it in integrating a CMMS with your ERP.
CMMS vs. ticketing system
A helpdesk manages requests: they come in, get assigned, get answered, get closed. And it does that well.
What it lacks is the asset. A hundred tickets about “machine 4” are a hundred tickets; in a CMMS they’re the history of one specific piece of equipment, with its accumulated cost, its downtime and its trend. It also lacks periodicity: a ticketing system doesn’t generate the work nobody has asked for yet, which is precisely what preventive maintenance does.
If your only problem is routing requests, a helpdesk may be enough. If you also need to know which equipment fails most often and whether it’s worth repairing, it isn’t.
CMMS vs. facility management
They overlap considerably and the difference is one of focus. A facility management tool looks at the space: square meters, occupancy, service contracts, cleaning, security, energy. A CMMS looks at the equipment.
In buildings where what’s managed is the use of the space, facility fits better. Where what’s managed is that the installations work — and it has to be proven — the CMMS is the right piece. Many organizations end up with both and an agreed boundary, just as with the ERP.
CMMS vs. field service software
Field service systems focus on the visit: planning routes, dispatching technicians, closing the job, invoicing. It’s almost the same thing until the asset and the obligation to prove show up.
A CMMS includes the field piece — in GMAO Cloud, the technician app with offline mode, a stopwatch, material consumption, checklists and signature — but it hangs it on the equipment’s history and the preventive plan, not just on the visit.
CMMS vs. spreadsheet
The comparison most companies actually face.
The spreadsheet isn’t a bad tool: with a handful of pieces of equipment, one site and one person, it can work for years. Its limit is that it doesn’t demand attention — a check that doesn’t happen doesn’t complain — it doesn’t record in the field — hours are jotted down from memory at the end of the day, always on the low side — and it doesn’t hold up as proof — a cell can be changed without leaving a trace.
The signs that it has run its course are specific: checks that slip by unnoticed, stock that never adds up, job records that don’t appear when a customer asks for them, and a technician who leaves taking what they knew with them. There’s a full inventory in the gaps a CMMS solves.
What none of the software on this list does
Fix a process that doesn’t exist. If nobody today decides who handles what and at what priority, the system will record the same disorder with more precision.
Set the periodicity. That’s set by the manufacturer, the regulation or technical judgment, and refined with the history.
Guarantee compliance with a regulation. Legally required maintenance relies on the history of work orders, completed checklists and documentation with its dates. The software records and proves; it’s the company that complies.
Where GMAO Cloud fits
It’s a CMMS, with the four things above, plus three product decisions that shape the rest: it’s cloud-based, so there’s no server to maintain; there’s no per-user fee, licenses are unlimited across all three plans; and each role signs in through its own door — backend for whoever plans, the app for whoever executes, dedicated access for the customer.
It has been developed since 2016 and is used today by more than 60 companies, with more than 2.8 million assets under management and more than 370,000 work orders logged during 2025.
The mistake of choosing by feature list
A practical warning, because it’s where most comparison time gets wasted.
Within the right category, every spec sheet says the same thing: work orders, preventive maintenance, assets, reports, mobile app. That list doesn’t discriminate, so the decision ends up being made on price or on whoever pushed hardest.
What actually discriminates are four things almost never on the spec sheet: how you pay as your fleet grows, whether the technician will actually use the app, what happens to old versions when there’s a major change, and how you get your data out if you ever decide to leave.
There’s a full guide on how to choose the best CMMS.
How to decide the category
Three questions are enough. Is what you manage equipment or requests? Do you need to generate work that nobody has asked for yet? Do you have to prove what was done to a customer, a regulation or an insurer?
If all three answers point to equipment, preventive maintenance and proof, the category is a CMMS. If you want to check it against your own case, you can request a demo.
