Size, veneer, glazing, hardware and opening side, previewed in 3D and validated against your production rules, priced live. The spec reaches production without retyping. The code is yours.
A wrong width, the wrong opening side, a different veneer shade. Ordering by phone and email produces these regularly. A configurator removes them at the source, because the customer orders exactly what they see and the rules block what cannot be made.
Minimum and maximum widths and heights, allowed combinations of glazing, frame and opening side. The customer cannot order what you cannot build.
Veneer, colour, glazing, handle and opening side change the view live. Nobody has to guess what "natural oak" looks like on their door.
Surcharges for size, glazing type and hardware, plus separate distributor price lists, all calculated on the server and impossible to tamper with.
If you sell through partner outlets, everyone orders the same way with the same validation. No more mixed forms and handwritten notes.
There is no door and window demonstrator in the public gallery yet. These are adjacent made-to-opening products on the same engine, so you can judge the build quality.

Infill, height and colour with dimension validation. The closest match for made-to-opening joinery.

sauna3d.grodev.plA fixed price after a short call, not a range with a hidden "from". One-off, no subscription.
A configurator for one range, for example interior doors: real-time 3D, dimension validation, server-side live pricing, mobile-tuned, lead or cart output.
The full catalogue of doors and windows, a complete rule set, an admin panel your staff run, distributor price lists and shop or ERP integration.
Against an off-the-shelf SaaS at €8,000 to 100,000 per year, a one-off build usually pays for itself inside 12 to 24 months. Full custom-vs-SaaS breakdown on the main configurator page.
A short note on your range, your size rules and how you price is enough. I reply within 48h with a fixed quote and a timeline.
