CMMS / GMAO
Maintenance management: assets, work orders, preventive, corrective, spare parts and history. This is the core, and what most people need.

What is a CMMS
If you got here searching for CMMS, you probably came from English-language documentation or an international vendor. The equivalence is direct, but there are nuances between acronyms worth knowing before comparing products.
CMMS, and its Spanish equivalent
CMMS stands for Computerized Maintenance Management System: the software where an organization manages the maintenance of its assets. Its Spanish equivalent is GMAO, Gestión del Mantenimiento Asistida por Ordenador. They’re the same concept, and in the Spanish market both terms are used interchangeably, with products presenting themselves as one, the other, or both in the same sentence. If you’re comparing tools, the acronym itself tells you nothing useful: what matters is what each one actually does.
The acronym map
Four categories that overlap, and that vendors use pretty freely.
EAM
Enterprise Asset Management. Adds the asset’s full lifecycle: valuation, depreciation and investment decisions. The line with a full CMMS is blurry.
APM
Asset Performance Management. Focused on reliability and prediction, usually with condition data and sensors. Assumes you already have history.
FSM
Field Service Management. Organized around the visit and the technician being dispatched, not the asset. Makes sense when the business is the service itself.
CAFM
Computer-Aided Facility Management. Manages space: floor area, occupancy, desks and moves. A different thing entirely, even when sold in the same package.
ERP
Manages the business: invoicing, accounting, purchasing. Complementary, not an alternative: the norm is to integrate your CMMS with it.
Why the acronym doesn’t help you choose
A vendor selling a CMMS with a depreciation module will call it an EAM, and one selling an EAM with no reliability analysis will still call it an EAM. The category gets used as marketing positioning, not as a technical spec, which is why comparing "CMMS versus EAM" is just comparing labels. What actually discriminates is a short list of concrete questions: can you define your own work statuses, what does the field app do without signal, how is it billed — per user or not — what does it take to get started, and what do you walk away with if you ever leave.
Other useful equivalences
If you work with English-language documentation, these are the translations that cause the most confusion. Work order is "orden de trabajo," also called "parte" in everyday industry usage in Spain. Preventive maintenance is "preventivo"; corrective maintenance, "correctivo"; condition-based maintenance, "mantenimiento basado en condición." Asset is "activo" or "equipo," and in Spanish it’s often called "máquina" depending on the sector. Spare parts are "repuestos" or "recambios." Downtime is "tiempo de parada," and uptime its opposite. MTBF and MTTR are used as-is, untranslated, even in Spanish documentation. And checklist coexists with "gama de mantenimiento," the traditional term in Spanish industry and still the more precise one.

What’s different about the Spanish market
If you’re coming from comparing international products, there are four differences worth keeping in mind. The first is pricing: a lot of English-language CMMS platforms bill per user per month, which gets expensive fast once you add technicians, customers and subcontractors into the mix. The second is regulatory compliance: the obligations of a facility in Spain — fire protection, thermal installations, Legionella prevention, lifting equipment — aren’t the same as in English-speaking markets, and a product that doesn’t account for them forces you to manage that separately. The third is language, and not just the interface: a field technician who doesn’t understand the screen won’t use it, and support in your own time zone matters more than it seems — until the day you need it. And the fourth is integration: the ERP you’ll find here is rarely the one that comes pre-integrated in a product built for a different market.
When a CMMS isn’t what you need
There are three situations where it’s worth pausing before comparing products. If what you manage are installation projects and you never go back to the equipment afterward, what you need looks more like project management or field service software than a CMMS: half its value — the history by asset — you’ll never use. If your problem is space, not equipment, what you need is a CAFM. And if what’s missing isn’t record-keeping but people, no system fixes that: a CMMS makes it visible that you’re short-staffed, more precisely and sooner, but it doesn’t add hands. Ruling out these three cases upfront saves everyone a lot of demos.
How the buying process usually goes
The typical journey has three phases, and it helps to know which one you’re in. In the first, you research and compare categories — probably where you are if you’ve landed here. In the second, you look at two or three products, and the common mistake is accepting the standard demo: ask for it on your own operation, with your asset types and your workflow, because a scripted demo makes every product look the same. And in the third, you negotiate, and what changes the outcome most isn’t the discount: it’s agreeing what’s included in the rollout, who builds the inventory, and what happens to your data if you ever leave.
Frequently asked questions
Is a CMMS the same as a GMAO?
Yes. CMMS is the English acronym for Computerized Maintenance Management System, and GMAO is the Spanish one for Gestión del Mantenimiento Asistida por Ordenador. They refer to the same product category.
What’s the difference between a CMMS and an EAM?
An EAM adds the asset’s full lifecycle — valuation, depreciation, investment decisions — on top of maintenance. In practice the line is blurry and each vendor draws it wherever suits them commercially.
What about an APM?
An APM focuses on reliability and prediction, usually with condition data. It assumes a well-recorded maintenance history already exists: without one, there’s no pattern to detect.
Do I need a CMMS or an FSM?
If you maintain assets over time — recurring contracts, preventive plans, history by unit — you need the asset at the center, and that’s a CMMS. If your business is one-off visits at a customer’s site, an FSM might be enough.
Do international CMMS platforms work in Spain?
Technically yes, but it’s worth checking three things: whether the product and support are available in Spanish, whether a per-user pricing model fits your size, and whether it accounts for Spanish regulatory obligations, which aren’t the same as English-speaking ones.
