Built to Align Every Team From Sale to Install.

One wrong configuration during the appointment means a custom window that fits no other home, an order that costs thousands, and months of delay. Every feature below exists to make sure that never happens.

Visual opening maps

Create a visual map of every opening from photos of the home so sales reps, measure techs, and installers always know which window belongs where.

Configuration validation

Prevent reps from selling window combinations that physically can't work together. The system catches invalid configurations before the order is placed.

Size and type validation

Prevent reps from selling window types that physically can't fit the opening. Catch sizing and configuration problems before the order reaches production or install.

Faster multi-window quoting

Quote dozens of custom window openings in a single appointment without rebuilding every configuration manually. Give reps a faster path from measurement to signed contract in the home.

Good/Better/Best packaging

Turn hundreds of configuration options into three clear packages homeowners can actually compare. Keep complexity inside the system while making the buying decision simpler during the appointment.

Clear handoffs

Keep opening labels, measurements, photos, and product details organized in one place so measure techs can easily verify every window without digging through scattered notes, photos, or disconnected systems.

KEY INTEGRATION

Manufacturer Catalog Integrations

Pull manufacturer catalogs, SKU systems, pricing, and product configurations directly into the platform so reps can quote complex window jobs quickly without manually cross-referencing catalogs or rebuilding configurations from scratch.
