CMMS Software Selection

What is a CMMS?

A CMMS is a database-driven system for managing maintenance activities. At its core, it does four things: tracks assets (what you own and where it is), manages work orders (what needs doing, who is doing it, what parts are needed), schedules preventive maintenance (recurring tasks triggered by calendar or meter reading), and records history (what was done, what it cost, what parts were used).

Without a CMMS, maintenance runs on paper WOs, spreadsheet PM schedules and tribal knowledge. The problem is not that paper fails entirely — it is that paper prevents analysis. You cannot calculate mean time between failure (MTBF), identify which assets are consuming the most maintenance labour, or demonstrate compliance to an auditor from a stack of completed work orders.

CMMS vs EAM: what is the difference?

Enterprise Asset Management (EAM) is the larger category. EAM covers the full asset lifecycle: capital planning, procurement, installation, operation, maintenance, and disposal — often integrated with financial depreciation schedules and capital project management. CMMS is the maintenance-focused subset of EAM.

For most small to mid-size manufacturers:

• CMMS is sufficient if your goal is preventive maintenance scheduling, work order management, and maintenance history. This covers the vast majority of SME needs.
• EAM is worth considering if you need capital budget tracking tied to individual assets, regulatory-grade asset lifecycle records (utility companies, oil and gas, heavily regulated industries), or integration with financial systems at the asset level.

Many products marketed as "CMMS" offer some EAM-adjacent features (depreciation tracking, capital planning). Whether you need them depends on whether your maintenance team and your finance team need to share the same asset database.

Core CMMS features to evaluate

Every CMMS claims to do all of this. The question is how well — and how easy the interface is for a maintenance technician who is not a power user:

• Asset hierarchy — asset → sub-asset → component structure; location/site hierarchy; asset numbering.
• Work order management — creation (manual, from PM trigger, from request), assignment, priority, status tracking, completion and close with actuals (labour hours, parts used).
• Preventive maintenance scheduling — calendar-based (every 30 days), meter-based (every 500 hours), or seasonal. Automatic WO generation from PM triggers.
• Parts inventory — spare parts linked to assets; minimum stock levels; reorder alerts; parts used per WO.
• Mobile access — technicians need to look up procedures, enter completions and take photos from the floor on a phone or tablet. Evaluate the mobile app, not the desktop.
• Maintenance history / reporting — WO history by asset; MTBF; maintenance cost by asset; labour utilisation; PM compliance rate.
• Requestor portal — a simple interface for non-maintenance staff to submit work requests (not full WOs). Keeps email and verbal requests out of the system.
• Integrations — does it connect to your ERP for purchasing or inventory? Can it receive alerts from your machine monitoring system?

CMMS pricing: what it actually costs

CMMS pricing structures vary more than most software categories. Common models:

Prices above are illustrative structure, not current vendor pricing. Always get a written quote with total cost of ownership, including implementation, training and any setup fees.

CMMS implementation checklist

The CMMS software itself is usually the easy part. Getting your asset data, PM schedules and historical records into the system is where implementations slow down. A practical sequence:

1. Asset inventory first. Walk the plant and list every maintained asset: name, location, manufacturer, model number, serial number. Do this before you sign a contract. If your asset list does not exist, create it in a spreadsheet first.
2. Define your PM schedule. For each asset, what PMs should be in the system? Source from OEM manuals, existing paper PM cards, or your maintenance team's knowledge. Prioritise: safety-critical assets first, then production-critical.
3. Set up your parts inventory (optional at first). You can start without it. Add parts inventory once WO management is working.
4. Import data. Most CMMS products accept CSV imports for assets and PMs. Clean your data before importing — duplicate assets and mismatched fields cause problems that are painful to fix post-import.
5. Train technicians on mobile. The biggest adoption risk. If technicians find the mobile app hard to use, they will revert to paper. Run the training with actual phones on the actual shop floor, not a laptop in a conference room.
6. Run parallel for 4–6 weeks. Keep the paper/spreadsheet system running while technicians learn the CMMS. Expect the transition to take longer than the vendor says.
7. Set PM compliance targets and review monthly. The metric to track is PM compliance rate: (PMs completed on time / PMs scheduled) × 100. A new system should reach 80%+ within 3 months.

Free CMMS options for small teams

Several CMMS products offer genuinely usable free tiers for small maintenance operations. The limitations are real but acceptable for a team of 1–3 technicians getting started:

• Typical free tier limits: 1–2 active users, limited asset count (50–200), no advanced reporting, no API access, sometimes no mobile app.
• What free works for: a single-site operation with one or two maintenance technicians, mostly preventive maintenance, and no compliance reporting requirement.
• What free does not work for: multi-site operations, more than 2–3 technicians, spare parts inventory management, compliance reporting for ISO or regulatory bodies.

Free tiers are a good way to test whether CMMS adoption is viable before committing to a paid plan. Run a 60-day pilot on the free tier with 2–3 real assets and real WOs before deciding.
