The verdict in three sentences
If your CMMS is only 40% filled in because technicians have to walk back to the office to log work, the problem is the interface, not the software. An offline mobile app connected to your existing CMMS costs 25,000 to 60,000 EUR excl. VAT and lifts the logging rate from 40% to 90% within three months. For a plant with 320 assets and 12 technicians, payback lands around 8 to 12 months.
Why the CMMS stays empty on the shop floor
In a plant around Grenoble, from Pont-de-Claix to Moirans, the pattern is the same: the CMMS (Carl Source, Mainti4, Coswin, SAP PM or another) runs on fixed workstations, technicians jot notes in a notebook or keep them in their heads, then log at the end of the shift, when they log at all. Production areas often have poor Wi-Fi coverage, which rules out standard web apps.
| Barrier to logging | Observed effect | Mobile app answer |
|---|---|---|
| Fixed workstation far from the shop floor | Logging delayed by 4 to 8 hours | Entry on a rugged smartphone next to the machine |
| No network in production areas | Web forms lost | Offline mode, sync when network returns |
| Searching for the asset in a tree | 2 to 3 minutes per work order | Machine QR code scan in 3 seconds |
| Too many mandatory fields | Rushed or abandoned entries | 4 essential fields, the rest optional |
| No visual evidence | Hard diagnosis for the next shift | Photos and voice notes attached to the order |
| Spare parts not tracked | Wrong stock, shortages | Part issue scanned from the job |
The goal is simple: a work order closed in under 90 seconds, standing up, wearing gloves.
What the app costs by scope
2026 orders of magnitude for a plant with 8 to 30 technicians, native or cross-platform development (Flutter, React Native), CMMS connector included.
| Level | Scope | Price (EUR excl. VAT) | Timeline | Annual maintenance |
|---|---|---|---|---|
| Core | Work orders, QR codes, photos, offline, CMMS API connector | 25,000 to 35,000 | 8 to 10 weeks | 3,500 to 5,000 |
| Standard | + daily preventive tasks, checklists, part issues, signature | 36,000 to 48,000 | 10 to 14 weeks | 5,000 to 7,000 |
| Advanced | + meter readings, LOTO lockout, dashboard, CMMS without API (database connector) | 49,000 to 60,000 | 14 to 18 weeks | 7,000 to 9,000 |
Add industrial QR labels (2 to 4 EUR each, so 640 to 1,280 EUR for 320 assets) and rugged smartphones (350 to 700 EUR per technician).
| Option | 3-year cost for 12 technicians | Fit with your processes | Limit |
|---|---|---|---|
| Paper and office entry | 0 EUR direct, about 100,000 EUR of lost time | Full | Incomplete data |
| CMMS vendor's mobile module | 15,000 to 35,000 EUR (40 to 80 EUR per user per month) | Medium | Heavy interface, partial offline |
| Custom Standard app | 51,000 to 69,000 EUR | Complete | Upfront investment |
| Full CMMS replacement | 80,000 to 200,000 EUR | Complete | Migration, 12-month project |
The vendor module is the right answer if technicians like its interface during a two-week trial. Otherwise, a dedicated app keeps your CMMS and history intact.
Driving adoption: the numbers to track
| Indicator | Before | Target at 3 months |
|---|---|---|
| Work orders logged | 40% | 90% |
| Delay between job and logging | 6 hours | Under 10 minutes |
| Preventive completion rate | 55% | 85% |
| Orders with a photo | 0% | 60% |
| Spare parts inventory variance | 12% | Under 4% |
Three rules make the difference: involve two technicians in the design from week one, remove the paper form on cutover day, and post the logging rate per team every week.

Mini case study
Julien, maintenance manager at a components plant in Grenoble, leads 12 technicians across 320 assets. Each technician spends 25 minutes a day logging at the office, versus 8 minutes with the app: 17 minutes saved × 12 technicians × 220 days = 748 hours a year, or 33,660 EUR at 45 EUR per loaded hour. Preventive completion rises from 55% to 85% and avoids about 20 hours of unplanned downtime a year at 1,500 EUR an hour: 30,000 EUR. Total gain: 63,660 EUR a year. Standard project: 42,000 EUR excl. VAT plus 6,000 EUR annual maintenance. Payback in about 9 months.
FAQ
Does our CMMS need an API?
It is preferable, and most CMMS products on the market offer one in 2026. Without an API, a database connector is still possible for an extra 6,000 to 12,000 EUR excl. VAT.
Does the app work without a network?
Yes, work orders, drawings and asset histories are stored on the phone. Sync happens as soon as Wi-Fi or 4G returns, usually in under 30 seconds.
Which phones should we choose?
An IP68 rugged smartphone between 350 and 700 EUR lasts 3 to 4 years on the shop floor. For 12 technicians, budget 4,200 to 8,400 EUR of hardware.
How long does technician training take?
A 2-hour session is enough if the app keeps only 4 mandatory fields. The logging rate usually exceeds 75% in the first month.
Can we start with a single production line?
Yes, a 6-week pilot on a line of 40 to 60 assets costs about 30% of the project. It lets you measure the gain before full rollout.
