About FlowManual
Summary
FlowManual builds takeoff and estimating software for general and MEP specialty contractors. It replaces disconnected spreadsheets and manual quantity counting by letting contractors measure drawings, count items, and price quantities in a single workspace, from the first sheet to the final bid proposal. The platform targets the pre-construction buying process, covering mechanical, ductwork, concrete, and general scopes.
Business model
Free to start, with paid plans above the free tier.
Go-to-market
Contractors start self-serve with no credit card required; a book-a-demo option serves teams that want a guided onboarding.
