# Configurable Building Products: Windows, Doors & Cabinetry Quoting

> How sellers of made-to-order windows, doors, and cabinetry run configure-to-quote: dimension-driven pricing, validated specs, and quotes that convert.

## Frequently asked questions

### Why can't made-to-order windows and doors be sold through a normal cart?

Because the price depends on dimensions and options that must be computed per configuration, manufacturing constraints and code requirements limit what is orderable, and custom units cannot be returned. An unverified dimension flowing straight to production is scrap with freight attached, so the flow ends in a verified quote rather than a checkout.

### What is configure-to-quote?

A flow where the buyer builds a complete, validated specification self-serve, series, dimensions, options, finishes, priced live against configuration rules, and submits it as a quote request. A rep verifies measurements, site conditions, freight, and lead time, and the approved quote converts to an order carrying the full spec into manufacturing.

### How does the quote step prevent dimension errors?

Two ways: the configuration exists as structured data, so revisions change the record instead of spawning new documents, and the approved specification flows to manufacturing as a bill of materials without retyping. Most dimension errors in made-to-order work are transcription errors, and the flow removes the transcription.

### Do builders and dealers use the same configurator as homeowners?

The same configuration logic with a trade account wrapped around it: trade pricing applied automatically, saved spec templates for repeated orders, and quotes organized by job or lot. A builder's forty-first door from a saved template is a two-minute task instead of a fresh specification.
