The verdict in three sentences
For a construction business that prices more than 500 quotes a year, an AI-assisted quoting tool pays for itself in under 12 months. The gain comes less from the AI itself than from the structured library of work items and prices it requires, and from automatically calculated MaPrimeRénov' grants that reassure the customer. Budget EUR 12,000 to 28,000 excl. VAT for a custom tool, with 8 to 14 weeks to go live.
Where the time goes in a renovation quote today
In an energy renovation company, a quote for insulation, a heat pump or a full renovation takes on average 3 hours: technical visit, measurements, supplier price lookups, grant calculation, formatting and follow-ups. Across 900 quotes a year, that is 2,700 hours, almost two full-time site managers or technical sales staff.
| Quote step | Manual time | With AI | What the tool does |
|---|---|---|---|
| Measurements | 45 min | 10 min | Quantities extracted from photos and PDF plans |
| Choice of work items | 40 min | 5 min | Suggests items from the internal library |
| Supplier prices | 30 min | 0 min | Prices synced with negotiated catalogues |
| Grant calculation (MaPrimeRénov', CEE) | 35 min | 5 min | Scale by income and zone, kept up to date |
| Formatting and legal notices | 20 min | 5 min | RGE-compliant template, 5.5% or 10% VAT |
| Follow-ups | 10 min | 5 min | Automatic reminders at D+3, D+7, D+15 |
| Total | 3 h | 30 min |
These times are a 2026 order of magnitude observed in companies with 15 to 50 employees. The technical visit stays human: AI speeds up office work, not on-site diagnosis.
What an AI quoting tool costs in 2026
There are three options. Off-the-shelf quoting software (Batappli, Obat, Tolteck and similar) is cheap but rarely includes photo-based measurements or fine-grained grant calculations. Custom software costs more upfront and fits your standard work items.
| Option | Upfront cost | Annual cost | AI measurements | Grants built in | Lead time |
|---|---|---|---|---|---|
| Standard quoting software | EUR 0 to 1,500 | EUR 600 to 2,400 | No | Partial | 2 weeks |
| Standard software + AI module | EUR 3,000 to 6,000 | EUR 3,000 to 6,000 | Basic | Partial | 4 weeks |
| Custom, core scope | EUR 12,000 to 18,000 excl. VAT | EUR 2,500 to 4,000 | Yes | Yes | 8 to 10 weeks |
| Custom, full scope | EUR 20,000 to 28,000 excl. VAT | EUR 4,000 to 6,000 | Yes, plans and photos | Yes, with out-of-pocket simulation | 12 to 14 weeks |
| AI API cost (included above) | EUR 0.05 to 0.40 per quote |
The full scope adds a connection to your accounting software, e-signature, MaPrimeRénov' file tracking and a conversion dashboard per salesperson.
What really lifts conversion
The move from 28% to 35% signed quotes comes from three measurable levers: speed (a quote sent within 24 h instead of 5 days), clarity on the out-of-pocket cost (the customer immediately sees the amount after grants) and consistent follow-ups. The first workstream is not technical: you need to structure 150 to 300 standard work items with their cost prices, which takes 3 to 5 weeks with your design office.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Thomas runs a 30-employee energy renovation company near Nantes, issuing 900 quotes a year at an average of EUR 14,000 excl. VAT. At 28% conversion he signs 252 jobs, or EUR 3.53M excl. VAT. After a custom tool at EUR 22,000 excl. VAT, quoting time drops from 2,700 h to 450 h: 2,250 hours freed, valued at EUR 45 an hour, or EUR 101,250. Conversion rising to 35% adds 63 jobs, or EUR 882,000 excl. VAT in extra revenue. Even with a cautious 31% assumption, payback comes in under 4 months.
FAQ
Can AI take reliable measurements from photos?
For wall, attic or window surfaces, accuracy reaches 90 to 95% with a size reference in the photo. The technician always validates the final measurement, which takes 5 to 10 minutes.
How are MaPrimeRénov' scales kept up to date?
Scales are stored in an editable table, updated with each regulatory change, usually once or twice a year. Updates are included in the annual maintenance of EUR 2,500 to 6,000.
Do we need to change accounting software?
No. The tool exports signed quotes to your existing software via API or file, which accounts for EUR 2,000 to 4,000 of the initial budget.
How long does team training take?
Plan half a day per salesperson and 2 weeks of supported use. Most teams produce quotes in 30 minutes from the second month.
Is customer data protected?
Hosting is in Europe, GDPR-compliant, and photos are not used to train AI models. This is written into the contract with the API provider.
