What Is a CMMS? Computerized Maintenance Management Software, Explained

CMMS stands for Computerized Maintenance Management System. It is software that keeps the records for maintaining your physical assets in one place: work orders, asset records, preventive maintenance schedules, parts inventory, vendor records, labor hours, and the reports built from all of that. If you are responsible for keeping equipment running and you are shopping for software, this is almost certainly the category you are looking at, whether or not you use the acronym.

The category started in industrial plants in the 1960s, was computerized in the 1980s, moved to the web in the 2000s, and is now being rebuilt around mobile devices, cloud hosting, and AI. Many cities and utilities still run maintenance on spreadsheets. The technology has existed for decades. For most of that time the established CMMS vendors priced their products well beyond what a typical municipal budget could cover. Newer platforms have brought that price down.

What a CMMS does

Set the marketing aside and a CMMS does six things:

1. Holds your asset registry. Pumps, hydrants, vehicles, buildings, and meters in one place, with location, install date, manufacturer, warranty, and service history.
2. Manages work orders. It covers the full work order lifecycle: intake, assignment, execution, close-out, and reporting.
3. Schedules preventive maintenance. Schedules can be time-based (every 90 days), meter-based (every 5,000 hours), or condition-based (when a sensor reading crosses a threshold).
4. Tracks inventory and parts. What is on the shelf, what was used on which job, and when to reorder.
5. Captures labor and cost. Hours, parts, vendor invoices, and total cost of ownership for each asset.
6. Reports. Dashboards, KPIs, asset histories, compliance exports, and budget detail.

Features beyond these six are usually extras, or they belong to a different kind of product.

CMMS vs. EAM vs. work order software

The terms overlap, partly because vendors use them loosely.

• Work order software handles the work order lifecycle and not much else. It works for small teams but falls short if you also need asset history.
• CMMS adds assets, PM scheduling, and inventory. This is what most public works, utility, and facility teams need.
• EAM (Enterprise Asset Management) adds capital planning, financial integration, depreciation, and full asset lifecycle modeling on top of a CMMS. It is aimed at large enterprises.

For most municipalities, a current CMMS with good reporting covers what EAM systems used to be sold for, at about a tenth of the price.

Signs your team needs a CMMS

• Nobody can say, today, how many work orders the Streets division closed last month.
• Preventive maintenance is something you'll get to when things slow down.
• Asset history lives in one foreman's head.
• Nobody knows the parts count until someone walks over to the shelf.
• Compliance reports get pieced together from spreadsheets the night before they are due.
• Residents report the same issue twice because the first ticket got lost.

If two or more of these sound familiar, a CMMS will usually pay for itself within the first year.

What to expect from a current CMMS

The category has changed a lot in the last five years. A CMMS bought in 2026 should include the following without extra charges:

• Mobile apps that work offline. Crews need to close work orders in basements and tunnels where there is no signal. More on offline use.
• Resident intake. A public request form that feeds the same system, with no separate product to buy.
• Built-in integrations. ESRI ArcGIS, SeeClickFix, telematics such as Samsara and Geotab, and 811 locates, without a professional services quote to connect them.
• Multiple divisions. Streets, water, sewer, refuse, facilities, and fleet each get their own roles and categories, with reporting across all of them.
• AI assistance. Help with triage, prioritization, asset health summaries, and questions about your data asked in plain language. A chatbot added to a settings page doesn't count.
• Pricing per organization. Per-seat pricing penalizes public works departments, which add seasonal staff through the year.

How long does CMMS implementation take?

Older enterprise systems typically take six to eighteen months. Current platforms can have the first division running in two to four weeks, and you add others from there. The older approach requires migrating everything before anyone goes live. With a newer platform, you can start with one division (usually Streets or Water), confirm the workflow fits, and bring on the others once staff trust it. Here is a phased migration plan.

What about cost?

Pricing varies a great deal. Older enterprise CMMS vendors still quote $50,000 to $150,000 a year for a mid-sized city, plus implementation fees. Multi-tenant SaaS platforms selling to the same cities usually price per organization, often in the low five figures a year, with no implementation invoice. If a vendor won't give you a number until you have sat through three demos and a discovery call, expect the price to be high.
