B2B catalogue landing with an interactive calculator for price-per-ton including delivery.

Clients wanted an instant «how much will a truck of crushed stone delivered to my site cost» — not a form and a phone call.
Built a transparent calculator: material → volume → address → price. The lead lands in the manager's pipeline pre-filled.
Lead conversion grew 27%, time-to-first-touch dropped from 2 hours to 15 minutes.
30 minutes — and you'll have a sense of scope, timeline and price.
