Do You Need a CMMS? When Yes and When Not Yet

The honest answer to whether you need a CMMS is that it depends, and not on your size. There are two-hundred-person companies that get by reasonably well with a spreadsheet, and six-person workshops that have been losing money for two years without knowing it.

What decides it isn’t how many assets you have: it’s whether the information still fits in one person’s head, and whether you have to prove what you do.

The signs that it’s no longer enough

None of these is serious on its own. If you recognize four or five, the decision has probably already been made without anyone stating it.

A check gets skipped and nobody notices until there’s a breakdown. It’s the clearest sign: it means the plan doesn’t push back.

Stock never adds up, and duplicate purchases of the same spare part show up.

Hours get logged from memory at the end of the day, so you can’t say what a job actually cost.

A client asks for a job report from months ago, and you have to track it down, or it doesn’t turn up at all.

You pay to repair equipment that’s still under warranty because nobody had the date at hand.

A technician leaves and takes with them what they knew about a specific site.

You can’t answer how much it costs to maintain a piece of equipment or whether a contract is profitable, and you defend it with a rough guess.

Requests come in through three different channels, and nobody has the complete list.

There’s a more detailed inventory in the gaps a CMMS should fix.

The four cases where the answer is simply yes

If even one of these applies, the conversation changes.

You have to prove what you do. If you have equipment subject to regulation or clients who demand proof of work, you need a record with a date, an author, and values that can’t be changed without leaving a trace. A spreadsheet cell isn’t that. Legal maintenance rests on the history of work orders, completed checklists, and documentation with its dates.

The work happens off-site. If your technicians are on other people’s premises, the record has to happen there. An app that works without coverage isn’t a convenience: it determines whether you get reliable data or reconstructions from memory.

You sell maintenance. If the preventive plan is what you’ve contracted with a client, failing to deliver it is a contractual problem before it’s an operational one, and the signed job report is what backs up the invoice.

You have several sites. As soon as the work is spread out geographically, nobody sees the whole picture and each site does its own thing.

When it still doesn’t pay off

By symmetry, and because it saves everyone time.

Few pieces of equipment, one location, and one person running everything. A well-kept spreadsheet can work for years. Its problem isn’t that it’s a bad tool: it’s that it has a ceiling, and it doesn’t warn you when you reach it.

All maintenance is outsourced and your role is to receive invoices. What you need first isn’t a system: it’s to require your provider to hand over job reports for what they do. Although that’s usually the first step toward wanting one, because once you have them, you want to be able to compare them.

There’s no process decided yet. If today nobody decides who handles what or with what priority, the software will record the same disorder with more precision. That gets agreed on beforehand, and it doesn’t cost money.

The fifteen-minute test

A cheap way to decide without talking to any vendor.

Pick any piece of equipment and spend fifteen minutes reconstructing its last year: what was done to it, when, by whom, how long it took, what materials were used, and what was found.

If you manage it by opening one place, you’re not in a hurry. If you need to cross-reference a spreadsheet with an email and call someone, you have one. And if there are blank months nobody can fill in, those months don’t exist in practical terms: not for a claim, not for insurance, not for deciding whether to repair or replace that piece of equipment.

The cost of waiting, which isn’t zero either

Putting off the decision looks free, and it isn’t. The cost doesn’t show up on any invoice, but it gets paid in four places.

The history that isn’t being built. This is the part you can’t recover later. Today’s orders can be logged tomorrow with some effort; what happened last year, if it wasn’t written down, doesn’t exist. Every month that passes is a month of data you’ll never have to decide whether to repair or replace.

The warranties that slip away. Repairing and paying for equipment that was still covered is a silent cost: nobody finds out, because finding out would require having the date in front of you the moment you open the job order.

The knowledge that walks out the door. It doesn’t give warning. It’s discovered the day someone leaves the company and nobody knows what needs checking on a specific piece of equipment.

The breakdowns caused by preventive maintenance that slipped. The check that didn’t happen in March doesn’t generate any alert: it generates a breakdown in October, and by then nobody connects the two.

None of the four forces a decision today. But it’s worth counting them, because the honest comparison isn’t “system versus nothing”: it’s “system versus what it costs to keep going like this.”

What to look at if the answer is yes

Four criteria that become noticeable six months in and almost never appear on the spec sheet:

How it’s billed. The per-user model gets complicated as soon as the team grows or you need to give access to clients and subcontractors: when each new account costs money, people share logins, and then the history stops being valid as proof. At GMAO Cloud, licenses are unlimited across all three plans.

Whether the technician will actually use it. Bring them to the demo. You’ll spot in two minutes whether the app is going to waste their time.

What happens to old versions when there’s a major update.

How you get your data out if you ever decide to leave.

What you can do this week, whatever you decide

Write the list of your critical assets — the ones that stop production or service if they fail — and, for each one, what’s done to it and how often.

It’s the task that takes the longest in any implementation, it’s worth the same with any tool, and if you finish it and discover you already had it all in your head, you’ve also learned something.
