The verdict in three sentences
In industrial joinery and similar made-to-order manufacturing, the first credible quote the customer receives often wins the job, and a 2 to 4 day quoting delay costs points of win rate. An off-the-shelf configurator (EUR 10,000 to 40,000 in licences) works well for catalogue products, but it cannot read an architect's specification or a PDF drawing. A custom AI automation that extracts the request, applies your costing rules and prepares a quote for the estimating team to approve (EUR 25,000 to 55,000, roughly USD 27,000 to 60,000, over 3 to 4 months) brings turnaround down to a few hours and targets a 10 to 25% uplift in conversion.
The real cost of an overloaded estimating team
In a 20 to 100 employee manufacturer of doors, windows and fit-out, an estimator handles 6 to 10 requests a week. Each quote takes 2 to 5 hours: reading the specification, taking off dimensions, choosing timber species and hardware, calculating machine and installation time. In Birmingham or Toronto, an estimator costs EUR 48,000 to 60,000 a year fully loaded.
| Requests per month | Quoting hours (3.5 h average) | Estimated monthly cost (EUR 32/h) | Average response time | Deals lost to delay (estimate) |
|---|---|---|---|---|
| 40 | 140 h | EUR 4,480 | 2 days | 8 to 12% |
| 80 | 280 h | EUR 8,960 | 3 days | 12 to 18% |
| 120 | 420 h | EUR 13,440 | 3 to 4 days | 15 to 22% |
| 160 | 560 h | EUR 17,920 | 4 days | 18 to 25% |
| 200 | 700 h | EUR 22,400 | 4 to 5 days | 20 to 30% |
The issue is not just the hourly cost: while estimators are quoting, they are not preparing production, which also stretches delivery lead times.
Off-the-shelf configurator or custom automation
| Criterion | Off-the-shelf configurator | Custom AI automation |
|---|---|---|
| Upfront cost | EUR 10,000 to 40,000 in licences and setup | EUR 25,000 to 55,000 |
| Recurring cost | EUR 200 to 1,000 a month + 15 to 20% annual maintenance | EUR 400 to 1,200 a month (hosting, AI, maintenance) |
| Reading requests (email, PDF, drawings) | No, manual re-entry | Yes, AI extraction of quantities, dimensions and finishes |
| Non-catalogue products | Difficult | Business costing rules and coefficients |
| Link to ERP or production software | Depends on vendor | Custom integration (items, times, bills of materials) |
| Human control | Full data entry | Review of a draft in 15 to 30 minutes |
| Time to deploy | 2 to 6 months | 3 to 4 months |
A configurator remains relevant if 80% of sales are standard catalogue products sold through dealers. Custom automation is justified when you answer tenders, developers or architects with mixed-format specifications.
How AI prepares the quote
The flow has four steps. AI reads the request (email, specification, schedule of quantities, PDF drawing) and extracts each item: type, dimensions, species, glazing, hardware, quantity. The rules engine, built with your estimating team, calculates material, machine time, finishing and installation. The estimator approves or corrects a draft. The quote goes out in your layout and feeds the CRM.
| Indicator | Before | After 3 months | After 6 months |
|---|---|---|---|
| Quoting time per request | 3.5 h | 1 h | 40 min |
| Response time | 3 days | 1 day | 4 to 8 hours |
| Quotes sent per estimator per week | 8 | 20 | 28 |
| Win rate | 22% | 25% | 26 to 28% |
| Gap between quote and actual cost | 8 to 15% | 6 to 10% | 4 to 7% |
The costing rules remain your property: they are documented and can be adjusted by the head of estimating without a developer.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
James, managing director of a joinery manufacturer near Birmingham (55 staff, EUR 7.5 million revenue), receives 100 requests a month and converts 22% of quotes, with an average order of EUR 18,000. His estimating team takes 3 days to respond. The custom project is quoted at EUR 42,000, plus EUR 800 a month. If the win rate rises to 26%, he signs 4 more jobs a month, EUR 72,000 of extra revenue. With a 30% contribution margin, the gain reaches EUR 21,600 a month. The project pays back in about 2 months of operation, before counting the 250 hours a month freed for production planning.
FAQ
Can AI really read an architect's drawing?
It reliably extracts door and window schedules, annotated dimensions and text specifications, with 85 to 95% accuracy. Poor-quality scanned drawings still need checking by the estimator.
Who sets prices and coefficients?
Your estimating team. The engine applies your rules and supplier prices; AI never sets a price on its own and every quote is approved by a person.
Do we need to change ERP?
No. The integration plugs into your existing software (Sage, Epicor, Dynamics, joinery-specific software) for EUR 4,000 to 10,000 depending on available APIs.
How long to go live?
Allow 3 to 4 months: 4 weeks formalising rules with the estimating team, 6 to 8 weeks of development, then 3 to 4 weeks of testing on real quotes.
Can we start with one product family?
Yes, and it is recommended. A first phase on internal doors or windows costs EUR 25,000 to 30,000 and proves the gain before extending.
