How to choose

Match the tool to your bottleneck.

If your bottleneck is the takeoff itself — the hours of counting and measuring before you can price — pick the most automated option (P2P). If you need a broad team platform and are fine measuring by hand, a mature tool like STACK or PlanSwift may fit. The fastest way to decide is to run a real blueprint through P2P free, with no login, and see how much of the bid is done for you.
