The verdict in three sentences
An online quote configurator costs EUR 35,000 to 70,000 excl. VAT in 2026 for a window manufacturer selling through a network of installers. It cuts the quoting time for a window from 2 days to 5 minutes and divides measurement errors by four, because the software enforces manufacturing rules instead of relying on one estimator's memory. 3D rendering remains an option (EUR 10,000 to 20,000) worth paying for only on product lines where it actually sells.
Why manual quoting costs more than it looks
Take a uPVC and aluminium window manufacturer, the kind found around Lille or in the English Midlands, with 300 installer resellers. Each request comes in by email or phone with rough dimensions. An estimator checks feasibility (min and max sizes, sash weight, hardware compatibility, glazing), applies the installer's discount and sends back a PDF. Average turnaround: two working days.
Meanwhile the installer chases, the homeowner compares with a competitor who answers within an hour, and part of the quotes never convert. Data entry errors are paid for in the factory: a window built to the wrong size means material, machine time and a second delivery.
| Item | Manual quoting | With a configurator |
|---|---|---|
| Average quote turnaround | 2 working days | 5 minutes |
| Quotes per estimator per day | 12 to 15 | Special cases only |
| Measurement error rate in production | 2 to 3% of orders | 0.5 to 0.7% |
| Average cost of an error (remake + delivery) | EUR 350 to 600 | Same, but 4 times less often |
| Installer discounts | Applied by hand from a spreadsheet | Automatic by price list |
| Hand-off to the factory | Re-keyed into the ERP | Direct export (CSV, XML or API) |
| Quote conversion rate (estimate) | 25 to 30% | 35 to 40% |
What a window configurator includes in 2026
A serious configurator is not just a form. Its core is a rules engine that encodes the constraints from your technical sheets: allowed sizes per range, opening direction, number of sashes, glazing type by surface area, options (roller shutter, glazing bars, dual colour), and price calculation from materials and labour.
| Module | Scope | 2026 budget (estimate) |
|---|---|---|
| Manufacturing rules engine | Constraints per range, compatibility, alerts | EUR 12,000 to 22,000 |
| Pricing and installer price lists | List price, multipliers, per-account discounts | EUR 6,000 to 12,000 |
| Installer portal | Accounts, history, quote duplication, branded PDF | EUR 7,000 to 14,000 |
| Production export | Cutting lists, ERP or joinery software export | EUR 5,000 to 12,000 |
| Pricing back office | Material price updates without a developer | EUR 3,000 to 6,000 |
| Testing, training, go-live | Pilot with 10 installers | EUR 2,000 to 4,000 |
| 3D rendering (option) | Window preview, colours, inside and outside view | EUR 10,000 to 20,000 |
| Maintenance and hosting | Fixes, minor changes, servers | EUR 600 to 1,500 per month |
The base total therefore sits between EUR 35,000 and 70,000 excl. VAT, depending on the number of ranges and the complexity of the export. The biggest budget driver is data quality: if your technical rules live in clean files, scoping takes a week. If they live in two estimators' heads, plan three to four weeks of interviews.
Custom build, joinery software module or SaaS?
Specialist joinery software vendors offer quoting modules, usually strong on the factory side but rigid for installers. A generic configure-price-quote (CPQ) SaaS is billed per user, which gets expensive with 300 installers. A custom build makes sense when your ranges have their own rules and the installer experience is a sales argument.
| Option | 2026 cost | Strength | Limit |
|---|---|---|---|
| Module from your factory software vendor | EUR 8,000 to 25,000 + licences | Native link to production | Dated installer interface, little customisation |
| Generic CPQ SaaS | EUR 40 to 120 per user per month | Fast start | 300 installers = EUR 12,000 to 36,000 per month |
| Custom configurator | EUR 35,000 to 70,000 + maintenance | Your rules, your brand, your discounts | Requires rigorous technical scoping |
Mini case study

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Thomas, sales director of a window manufacturer near Lille, handles 1,800 quotes a year. Two estimators spend the equivalent of 1.2 full-time jobs on them, about EUR 55,000 in annual loaded cost. A 2.5% error rate on 900 orders means 22 remakes at EUR 450, or EUR 9,900 a year.
With a EUR 52,000 configurator, estimator time on quotes drops to 0.3 of a job (saving EUR 41,000 a year) and errors fall to 6 a year (saving EUR 7,200). Gaining 5 conversion points on 1,800 quotes at an average order of EUR 2,400 adds margin well beyond that. Payback: about 13 months on savings alone, before any revenue growth.
FAQ
How long does it take to launch a window configurator?
Plan 12 to 16 weeks from scoping to go-live for 3 to 5 product ranges. The longest phase is formalising technical rules, often 3 to 4 weeks.
Can prices differ by installer?
Yes, each installer account gets its own multiplier or discount list, from 15 to 40% depending on volume. Homeowners browsing the site never see those terms.
Is 3D rendering essential?
No. For standard windows, a dimensioned 2D drawing is enough and costs EUR 3,000 to 5,000. 3D (EUR 10,000 to 20,000) pays off for entrance doors and bespoke sliding doors, where looks drive the decision.
How does the configurator talk to the factory?
Through a structured export (CSV, XML or API) to your ERP or joinery software. That module costs EUR 5,000 to 12,000 and removes re-keying.
Who updates prices when aluminium goes up?
Your team, from a back office: one material multiplier changed updates every quote within seconds, with no developer involved.
Let's scope your project. Send us your product ranges, number of installers and factory software: we will price a configurator between EUR 35,000 and 70,000 with a 12 to 16 week plan. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
