The verdict in three sentences
If your maintenance fits into work orders and a preventive schedule, an off-the-shelf CMMS at USD 3,300 to 16,000 a year is enough and goes live in 2 to 3 months. Once you want maintenance triggered by your PLCs (run hours, vibration, temperature) and downtime costs tracked line by line, a custom CMMS at USD 38,000 to 76,000 (EUR 35,000 to 70,000) pays back within 18 to 30 months. The deciding factor is your hourly cost of downtime, not the licence price.
What each option really costs over 5 years
A maintenance manager at a plant in the Toronto manufacturing belt (automotive parts, plastics, food processing) typically oversees 350 assets, 8 to 12 technicians and a maintenance budget of 4 to 6% of revenue. Comparing licences is not enough: configuration, integrations and changes must be counted.
| Cost item | SaaS CMMS (SMB tier) | Enterprise CMMS package | Custom CMMS |
|---|---|---|---|
| Setup | USD 3,300 - 8,700 | USD 16,000 - 43,000 | USD 38,000 - 76,000 |
| Annual subscription or maintenance | USD 3,300 - 7,600 | USD 8,700 - 16,000 | USD 5,400 - 10,800 |
| PLC integration (OPC UA, MQTT) | Often limited or add-on | USD 10,800 - 27,000 | Included in scope |
| Rollout time | 1 - 3 months | 4 - 8 months | 5 - 8 months |
| 5-year total cost (2026 estimate) | USD 20,000 - 47,000 | USD 70,000 - 150,000 | USD 65,000 - 130,000 |
| Ownership of code and data | No | Data yes, code no | Yes, fully |
Custom is not necessarily pricier over 5 years than a heavy package with connectors. It clearly is compared with a simple SaaS: if you do not need machine data, do not go custom.
The KPIs that justify the investment
A CMMS is judged on three numbers: availability of critical assets, the share of preventive work in maintenance hours, and breakdown costs. Plants moving from spreadsheets to a connected CMMS typically see the following gains, as an order of magnitude.
| KPI | Before (spreadsheet or paper) | After 12 months of connected CMMS |
|---|---|---|
| Critical asset availability | 88 - 91% | +3 to +5 points |
| Preventive share | 30 - 45% | 65 - 75% |
| Annual breakdown cost | Index 100 | Divided by 1.8 to 2 |
| Time spent finding parts | 25 - 40 min per job | 5 - 10 min |
| Spare parts inventory | Index 100 | -15 to -25% |
| Work order close-out time | 3 - 7 days | Same day |
Levers specific to custom: condition-based maintenance triggered by PLC thresholds, an offline-capable mobile app for technicians in dead zones of the shop floor, and a downtime cost dashboard per line shared with production.
Mini case study
Claire, maintenance manager at a plastic parts plant near Toronto, suffers 180 hours of unplanned downtime a year on 4 critical lines, at USD 1,300 of lost margin per hour, or USD 234,000. She chooses a custom CMMS at USD 63,000 connected to her Siemens PLCs. Within 12 months, preventive work rises from 40% to 70% and downtime falls to 95 hours: USD 110,000 of margin recovered in year one. With USD 7,600 of annual maintenance, payback comes in about 7 months, and spare parts inventory drops by USD 19,000 along the way.

FAQ
What does a CMMS cost for a mid-sized manufacturer in 2026?
A simple SaaS costs USD 3,300 to 7,600 a year; an enterprise package USD 16,000 to 43,000 to set up plus maintenance. A custom CMMS ranges from USD 38,000 to 76,000.
Can a CMMS connect to our existing PLCs?
Yes, through OPC UA or MQTT on most recent Siemens, Schneider or Rockwell controllers. Budget USD 10,800 to 27,000 if the vendor sells it as an add-on.
How long to reach 70% preventive?
Usually 9 to 15 months, the time needed to clean up the inventory of 350 assets and maintenance routines. The first 3 months are mostly data collection.
Is there funding for this kind of project in Ontario?
Provincial and federal programmes for manufacturing digitisation often cover 20 to 50% of eligible costs, subject to criteria; check current calls before committing.
What happens to a custom CMMS if the vendor disappears?
You own the source code and documentation, delivered at acceptance. Another integrator can take over maintenance after 2 to 4 weeks of onboarding.
Let's scope your project. We price your CMMS from your asset base (number of assets, PLCs, sites), with an indicative budget between USD 38,000 and 76,000 and a 5 to 8 month rollout. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
