CMMS software cost: off-the-shelf vs custom
Off-the-shelf CMMS software typically costs $30-150 per user per month in recurring subscription fees, while custom-built CMMS software runs $40,000-150,000+ as a one-time project cost with no recurring per-seat license. Which is cheaper depends almost entirely on team size and how long you plan to run the system, not on which option is inherently "better."
The cost breakdown by approach
| Cost factor | Off-the-shelf CMMS | Custom-built CMMS |
|---|---|---|
| Upfront cost | Low: setup fees typically $2,000-15,000 | Higher: typically $40,000-150,000+ depending on scope |
| Recurring cost | $30-150 per user/month, indefinitely | Hosting and support only, roughly $500-3,000/month |
| Scaling cost | Grows linearly (or faster) with headcount | Flat regardless of user count added |
| Time to launch | Days to a few weeks | 2-5 months typically |
| Fit to unusual equipment | Limited to vendor's data model | Built to match your actual assets and workflows |
| Integration flexibility | Limited to vendor's API and partner list | Whatever your systems actually need |
| Ongoing vendor risk | Pricing changes, feature paywalls, acquisition risk | None; you own the codebase |
Doing the long-term math
The subscription model looks cheap in year one and gets expensive by year three, particularly as teams add users. A 25-user deployment at $75/user/month is $22,500 a year, or roughly $112,500 over five years, before counting the near-certain price increases most SaaS vendors apply annually. A custom build at $80,000 upfront plus $1,500/month hosting and support runs closer to $170,000 over five years for the same period, but that gap narrows or reverses entirely once you factor in headcount growth: at 60 users, the subscription model alone exceeds $270,000 over five years while the custom system's hosting cost barely moves.
The crossover point where custom becomes cheaper depends on your specific numbers, but as a rough guide, teams with 40+ regular CMMS users planning to run the system for 4+ years are the ones where the math most often favors building.
When custom actually makes sense
Cost alone isn't the only, or even the primary, reason to build custom. Three situations come up repeatedly with teams that move off an off-the-shelf platform.
Unusual equipment mix. Off-the-shelf CMMS products are built around generic asset models: pumps, motors, HVAC units. If your equipment is specialized (custom fabrication lines, proprietary machinery, mixed fleet plus facility assets in one system), you end up forcing your data into fields that don't fit, and workarounds accumulate.
Specific compliance needs. Some industries need maintenance records structured in a particular way for audits, inspections, or regulatory reporting. Generic CMMS platforms support the common frameworks well; less common or industry-specific requirements often need custom reporting or data structures the vendor won't build for one customer.
Avoiding subscription costs at scale. Once a maintenance team grows past a few dozen users, or once the CMMS needs to talk to ERP, SCADA, or IoT sensor data the vendor doesn't natively support, the per-seat model starts working against you rather than for you.
If none of those apply, off-the-shelf is usually the faster, cheaper, lower-risk starting point. If two or more do, it's worth running the actual numbers for your team size and time horizon. Our CMMS and maintenance management team can walk through that comparison against your specific equipment list and user count.
