The verdict in three sentences
When a staircase quote takes 14 days, the installer signs with the competitor who answers in 48 hours. A custom quote configurator turns the design office's pricing rules into an online tool with a 3D view and an instant price. The real gain comes downstream: the bill of materials goes straight to production, with no re-keying and no dimension errors.
The hidden cost of hand-made quotes
The managing director of a 65-employee timber and steel staircase maker in Brandenburg, just outside Berlin, receives 450 requests a month: 70 % from installers in his network, 30 % from homeowners. Two technicians price each request from sketches, photos and often incomplete measurements. Result: 14 days average turnaround and an 18 % conversion rate.
| Indicator | Today | Target with a configurator |
|---|---|---|
| Average quote time | 14 days | instant for 70 % of cases, 48 h for the rest |
| Technician time per quote | 1 h 45 | 20 min (review only) |
| Requests handled per month | 450 | 450 to 600 |
| Conversion rate | 18 % | 24 to 28 % (2026 order of magnitude) |
| Dimension errors in the workshop | 4 to 6 a month | under 1 a month |
| Re-keying into production | 30 min per order | zero, automatic export |
At 450 requests of 1 h 45, pricing absorbs nearly 790 hours a month, more than two technicians can supply. Hence the delays.
What the configurator must do
The catalogue holds about 1,800 useful combinations: woods (oak, beech, ash, walnut), shapes (straight, quarter turn, half turn, spiral), stringers, treads, risers and balustrades (wood, steel, glass, cable). Not all are compatible, and that is where the value lies: the design office's rules, including DIN 18065 stair geometry, become constraints in the tool.
| Feature | Generic market configurator | Kolonell custom build |
|---|---|---|
| Measurement entry (opening, rise, going) | simple form | walking comfort check (DIN 18065, step formula) |
| Compatibility rules | limited | all design office rules |
| 3D view | fixed models | generated from dimensions and choices |
| Pricing | single price list | separate trade and homeowner prices |
| Bill of materials and cutting list export | no | yes, to the ERP or as CSV for CNC |
| Installer portal with history | rare | included |
| Cost | 300 to 1,500 EUR a month as SaaS | 3,810 to 22,870+ EUR (2.5 to 15M+ FCFA) depending on complexity |
This scope falls in the complex band of our grid, 10,670 to 22,870+ EUR (7 to 15M+ FCFA), with a 4 to 6 month timeline. Maintenance is 53, 114 or 183 EUR a month. The interface with the production ERP is quoted based on its API.
The installer network as a sales lever
Installers want a fast price to show their end client. The installer portal gives them trade pricing, their past quotes, the option to add their own fitting margin and a PDF on their letterhead. The manufacturer becomes the easiest supplier in the market, which builds loyalty better than another discount. Homeowners get an indicative range and are routed to the nearest installer.
One more design choice matters: what the homeowner sees. Showing a range rather than a firm price, for example 6,800 to 8,200 EUR installed, protects installer margins and keeps the manufacturer out of price disputes. The configurator stores every configuration, so the sales team can follow up on the 60 % of homeowners who leave without requesting a visit, with a reminder after 7 days.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Matthias, the managing director, runs the numbers. Technician time drops from 1 h 45 to 20 minutes per quote: 450 × 1.42 h = about 640 hours freed each month. Conversion rises from 18 % to 24 %, so 27 more orders a month on 450 requests. At a gross margin of 1,400 EUR per staircase, that is 37,800 EUR of extra margin a month. For a configurator budgeted at 22,000 EUR plus Premium maintenance at 183 EUR a month, payback is measured in weeks, even if the real uplift is only half the assumption.
FAQ
Does the 3D view slow the site on mobile?
The model is lightweight, around 1 to 2 MB, and loads in under 3 seconds on 4G. A 2D fallback view shows on older devices.
Can we change prices without a developer?
Yes, a back office lets you update wood and balustrade prices with a full history. A 5 % rise in oak goes live in a minute.
What about the 30 % of unusual requests?
The configurator flags out-of-rule cases and sends them to the design office with all dimensions already captured, cutting pricing to about 45 minutes.
Can the bill of materials feed our CNC machines?
Yes, the export lists cuts, dimensions and machining. The exact format depends on your CAM software and is agreed at kickoff.
How long until the first launch?
Allow 4 to 6 months, starting with straight and quarter-turn stairs, which often make up 70 % of requests.
