Where door & window manufacturers lose deals online

Three problems, one fix

01

The catalog maze

A homeowner replacing their entry door has 40 questions. Your website answers zero. They scroll, get overwhelmed, and leave — or call a dealer who spends 30 minutes on discovery that should've taken five.

02

Leads your dealers won't work

A name and an email arrive. No product. No budget signal. Dealers who don't know what the buyer needs don't call back. And you've spent money generating pipeline that never converts.

03

One site, three audiences

A homeowner, a contractor, and an architect all land on the same page. They need completely different experiences. Your website gives them all the same one.

The solution

An AI agent that sells the way your best rep does

Your best rep doesn't hand a buyer a catalog and walk away. They ask what the project is, what the house looks like, what the budget is — and then recommend the right product, the full package, and the upgrade path.

Threekit puts that expertise on your website. The agent asks the right questions, narrows your full product line to the right fit, and hands off a lead that already has a door or window selected, a style preferred, and a budget indicated.

Dealers get leads they can actually close. Your website stops being a catalog and starts doing sales work.

What it does

Built for how door & window buyers actually shop

Guided product selection

Walks buyers through style, material, size, and application — in plain language, not spec sheets. Works for homeowners, contractors, and architects on the same platform.

Photo upload & instant match

Buyer uploads a photo of their current door or window. The agent analyzes the style, identifies compatible replacements and upgrades, and builds a recommendation — no form fields required.

Bundle & upsell builder

A buyer comes in for a front door. The agent surfaces the sidelights, the frame, the hardware finish, the storm door. Buyers leave with the full solution. AOV goes up.

Dealer lead routing

Every lead routes to the right dealer automatically — with product selected, budget signaled, and intent attached. The first call starts with context, not cold discovery.

Multi-audience paths

Homeowners get a simple, visual experience. Contractors and architects get spec-level depth. One agent. One platform. No duplicate builds.

Live in 90 days

Sits on top of your existing product data, pricing tools, and CRM. No rip-and-replace. Marketing moves without waiting on IT to greenlight a multi-year infrastructure project.

Social proof

Guided selling recommends styles based on architectural design preferences, then passes the selection to back-end pricing tools to generate a quote.

The outcomes

What changes when your website does the selling?

Increased CVR

More leads from existing traffic

Buyers who get guided convert. Buyers who hit a catalog and can't navigate leave. The agent eliminates the drop-off.

Higher AOV

Higher average order value

Buyers guided to complete solutions spend more than buyers who find a single SKU and stop. The agent always asks the next question.

Less time to close

Better dealer follow-through

Leads arrive with product selected, budget signaled, and intent attached. Dealers know what to say on the first call — so they make it.
