The verdict in three sentences
A custom CMMS plans work orders, manages the spare-parts stock and tracks every asset, with a mobile app in the technicians' hands. Budget 40,000 to 95,000 EUR (excl. VAT) over 14 to 24 weeks, with the field app alone accounting for 20 to 35% of the budget. The return shows as downtime avoided and a shift from reactive to preventive maintenance.
Off-the-shelf CMMS vs custom
Mobility Work or DIMO Maint cover the essentials as SaaS but charge per user and frame your processes. Custom fits your asset base and maintenance procedures. 2026 orders of magnitude for a site of 10 to 60 technicians.
| Criterion | SaaS CMMS (Mobility Work/DIMO) | Custom |
|---|---|---|
| Setup | 10,000 - 60,000 EUR | 40,000 - 95,000 EUR |
| Subscription | 30 - 70 EUR/user/mo | 0 EUR (hosting) |
| Specific maintenance procedures | Standard | Total |
| Offline mobile app | Vendor-dependent | Custom |
| MES/ERP/stock link | Connectors | Native |
| Code ownership | No | Yes |
For 40 technicians at 50 EUR/month, SaaS costs 24,000 EUR/year, i.e. 120,000 EUR over 5 years: custom prevails once procedures and assets are specific.
The field mobile-app line item
A CMMS's value plays out on the ground: a technician logging work in real time, even without a signal, feeds reliable data. Indicative 2026 breakdown.
| Mobile feature | Effort (days) | Cost (2026) |
|---|---|---|
| Work orders + offline entry | 12 - 18 | 9,000 - 14,000 EUR |
| Asset/part QR scan | 5 - 8 | 4,000 - 6,500 EUR |
| Spare-parts consumption | 6 - 10 | 4,500 - 8,000 EUR |
| Photos, checklists, signatures | 5 - 9 | 4,000 - 7,000 EUR |
| Preventive/urgent notifications | 4 - 7 | 3,000 - 5,500 EUR |
A complete mobile app represents 25,000 to 40,000 EUR: it is the lever for maintenance-data reliability.

| Metric | Before | After CMMS | Effect |

| Equipment lifespan | baseline | +10% | Cost of ownership |
Mini case study
Antoine, maintenance manager at a 40-technician food-processing site near Rennes, suffers about 300 h/year of unplanned downtime on his lines. Each downtime hour costs 1,200 EUR in lost production, i.e. 360,000 EUR/year. Cutting downtime by 15% through preventive work and parts availability saves 54,000 EUR/year. His custom CMMS costs 72,000 EUR plus 11,000 EUR/year maintenance: the project is paid back in about 16 months, before counting fewer part stockouts and longer equipment life.
FAQ
Does the mobile app work without a signal in the workshop? Yes: it is designed with an offline mode that syncs as soon as the connection returns, essential in poorly covered technical areas.
Can it manage the spare-parts stock? Yes: the CMMS tracks consumption per work order, triggers reorder thresholds and prevents stockouts on critical parts, one of the main sources of gain.
Does it connect to the MES or ERP? Yes, via API: MES machine stoppages can generate work requests, and part purchases flow to the ERP, removing double entry.
How long to get started? Expect 14 to 20 weeks for a work-orders base plus mobile app; preventive maintenance and reliability analysis are added later in increments.
What annual maintenance budget? Plan 12 to 18% of the build per year, i.e. 9,000 to 17,000 EUR/year on a 72,000 EUR project, hosting included.
