The verdict in three sentences
For a fit-out and finishing contractor in Amsterdam (35 staff, 600 quotes a year, 25% won), an AI quote generation tool costs between EUR 40,000 and 80,000 in 2026, plus EUR 150 to 450 a month in AI usage. It reads PDF drawings, extracts areas and lengths, applies the company's price library and produces a quote ready for review. Time per quote drops from 3 hours to 1 hour, 1,200 hours recovered a year, and replies go out in 48 hours instead of a week.
What the tool does, step by step
The estimator uploads the PDF drawing or bill of quantities from the architect. The AI detects rooms, measures tiling, ceiling and painting areas and lengths of skirting or ducts, then proposes quantities with a confidence score. The estimator validates or corrects, the tool applies unit prices and waste factors, then generates the quote on company letterhead.
| Module | Function | 2026 estimate (EUR) |
|---|---|---|
| PDF drawing reader | Room detection, dimensions, scale, area and length extraction | 12,000 to 23,000 |
| Price library | Work items, unit rates, suppliers, waste and labour factors | 7,000 to 14,000 |
| Quote generation | Trades, subtotals, 21% VAT, terms, PDF and Excel export | 6,000 to 12,000 |
| Validation and history | Correction screen, versions, won vs lost comparison | 5,000 to 10,000 |
| Price updates | Supplier price list imports (plasterboard, tiles, cables) | 4,000 to 9,000 |
| Training and historical quotes | 200 past quotes analysed to calibrate prices | 6,000 to 12,000 |
| Total | 40,000 to 80,000 |
Monthly AI cost depends on the number of drawing pages processed: about EUR 0.10 to 0.15 per page, so EUR 150 a month for simple jobs and up to EUR 450 for tenders with dozens of drawings.
Manual quotes, classic estimating software or AI: the comparison
| Criterion | Excel quotes | Classic estimating software | Custom AI tool |
|---|---|---|---|
| Upfront cost | EUR 0 | EUR 3,000 to 8,000 in licences | EUR 40,000 to 80,000 |
| Recurring cost | EUR 0 | EUR 80 to 200 per seat per month | EUR 150 to 450 a month plus EUR 500 maintenance |
| Time per quote | 3 hours | 2 hours | 1 hour |
| Automatic take-off from PDF | No | Partial, often from DWG or IFC | Yes |
| Local price library | Scattered files | Entered manually | Built from your past quotes |
| Average response time | 5 to 7 days | 3 to 5 days | 1 to 2 days |
| Quantity errors observed | 5 to 10% | 3 to 5% | 1 to 3% after validation |
AI does not replace the estimator: it removes the mechanical part of the job. On poor-quality drawings, photocopied or without dimensions, the confidence score drops and the tool flags it.
Why speed changes the win rate
On Amsterdam private projects (office refurbishments at the Zuidas, apartment fit-outs in Noord, retail units in the centre), the first complete quote the client receives has a clear edge. Replying in 48 hours instead of 7 days often lifts the win rate from 25% to 30 or 32%. The tool also lets the contractor answer tenders it currently turns down for lack of time.
Mini case study
Daan, managing director of a tiling, drywall and painting contractor in Amsterdam, employs 2 estimators at EUR 5,200 a month fully loaded. His 600 quotes a year at 3 hours represent 1,800 hours. With an AI tool at EUR 60,000, he saves 2 hours per quote, 1,200 hours, the equivalent of 0.75 of a role, about EUR 47,000 a year. More importantly, his win rate rises from 25% to 29% on an average job of EUR 45,000: 24 extra jobs a year at 12% margin, or EUR 130,000 of additional margin. With EUR 300 of AI and EUR 500 of maintenance a month, the project pays back in about 4 months.

FAQ
Does the tool work with scanned drawings?
Yes, if the scale is readable. On an average scanned drawing, the AI gets 85 to 90% of quantities right before correction, versus 95% on a vector PDF.
Can it read BIM models?
Yes, an IFC import can be added for EUR 6,000 to 10,000. Quantities then come straight from the model, with near-zero measurement error.
Do our prices stay confidential?
Yes. The price library is stored in your own environment and is not used to train a public model. Only drawings are sent to the AI model, never your margins, in line with GDPR.
How long until we are up and running?
Allow 10 to 14 weeks, including 3 weeks to rebuild the price library from 200 existing quotes.
Can payment be staged?
Yes, usually 40% at kick-off, 40% at delivery and 20% after one month of use.
