Builder Prime is an all-in-one CRM and business management platform built for home improvement contractors and remodelers. It combines lead and client management, appointment setting, estimating and price books, proposals and e-signature contracts, project and production scheduling, invoicing and payments, SMS and email communication, marketing automation, and sales reporting in a single multi-tenant web and mobile application. Each customer works from its own subdomain, and Builder Prime exposes a REST "Open API" plus webhooks and a Zapier app so contractors can push leads and pull client, employee, project and appointment data between Builder Prime and lead aggregators, call centers, financing partners, measurement tools and accounting systems.
