The verdict in three sentences
In renovation, the first quote received is often the one signed: going from 7 days to 24 hours matters more than a few euros of price difference. An AI that turns a dictated site visit and photos into a structured quote, based on your price library, costs EUR 10,000 to 25,000 excl. VAT and frees 8 to 10 hours a week for the owner. Human review remains mandatory: the AI prepares 90% of the quote, the professional validates quantities, contingencies and margin.
How the AI builds a renovation quote
During the visit, the owner or site manager dictates observations on their phone ("bathroom 6 m², remove wall tiles, rework plumbing, low-profile shower tray 90 × 120") and takes 10 to 30 photos. The system transcribes, structures by trade (demolition, plumbing, electrical, tiling, painting), finds the matching work items in the company's price library, calculates quantities and proposes a quote in the usual format, with VAT at 10% or 5.5% depending on the nature of the works in France. Photos help spot forgotten items and document the initial condition.
| Step | Manual method | With AI quoting |
|---|---|---|
| Note-taking during the visit | Notebook, 45 min | Dictation + photos, 45 min |
| Transcription and take-off | 1 h 30 to 2 h | 5 min, automatic |
| Looking up prices and items | 1 h | Automatic from the library |
| Quote formatting | 45 min | Automatic |
| Review and margin adjustment | 15 min | 20 to 30 min |
| Time to send to the client | 5 to 7 days | 24 h |
Project cost in 2026
The core of the value is the price library: 300 to 1,500 work items with material costs, labour time and margin coefficients. If it already exists in software (Batappli, Obat, Tolteck, EBP Bâtiment), it is reused; otherwise building it is a significant part of the project.
| Item (2026 order of magnitude) | Essential version | Advanced version |
|---|---|---|
| Reuse or creation of the price library | EUR 2,000 to 4,000 | EUR 5,000 to 8,000 |
| Site visit app (dictation, photos) | EUR 3,000 to 5,000 | EUR 5,000 to 7,000 |
| AI structuring and pricing engine | EUR 3,000 to 5,000 | EUR 5,000 to 7,000 |
| Export to quoting software or PDF | EUR 1,000 to 2,000 | EUR 2,000 to 3,000 |
| Quote tracking and automatic follow-ups | Not included | EUR 1,000 to 2,000 |
| Total project | EUR 10,000 to 15,000 excl. VAT | EUR 18,000 to 25,000 excl. VAT |
| Monthly cost (AI, transcription, hosting) | EUR 100 to 200 | EUR 200 to 400 |
These amounts are estimates for a company of 10 to 50 employees. Digitalisation grants for small businesses (regions, chambers of trades) may cover part of the budget depending on the area.

The AI knows neither the real condition of a wall behind tiles nor the client's temperament. Three rules apply: every quote is reviewed and signed by an authorised person; risky items (structural repairs, asbestos, old networks) trigger an alert and a contingency line; the minimum margin per trade is locked to prevent a quote below cost. The typical schedule is 6 to 8 weeks, including 2 weeks of tests on already-priced jobs to compare the AI with real quotes.
Mini case study
Julien, owner of a 20-employee renovation company in Bordeaux, issues 25 quotes a month averaging EUR 18,000 excl. VAT and signs 25% of them. He spends 12 hours a week on them. With an AI quoting tool at EUR 18,000 excl. VAT, that time drops to 3 hours: 9 hours saved per week, about 400 hours a year redirected to site supervision. Thanks to 24-hour turnaround, his signing rate rises from 25% to about 28.75% (+15%), i.e. nearly 11 extra jobs a year out of 300 quotes. At a 12% net margin, that is about EUR 23,800 of additional margin. The project pays back in under a year on that effect alone.
FAQ
Can the AI quote without a visit? For simple work (painting, equipment replacement), an indicative quote from client photos is possible. For heavy renovation, the visit remains essential and the AI only cuts office time by 70 to 80%.
What happens when material prices rise? The library can be indexed to supplier price lists or updated by quarterly import. A 5% increase on one trade flows into all new quotes within a minute.
Do we need to change quoting software? No, most projects export to the existing software. A dedicated connector usually costs EUR 1,000 to 3,000 excl. VAT depending on the available API.
Are mandatory legal mentions included? Yes, templates include ten-year liability insurance, reduced VAT with certificate, payment terms and validity period. Their legal check is done once, during setup.
How long until the team is autonomous? Learning the site visit app takes about 2 hours. After 20 to 30 quotes, the team validates a full quote in under 30 minutes.
