A dedicated estimator needs different tools from a contractor who has one bid to get out between site visits. Start with the plan, the people doing the takeoff, and the price basis you need to defend.
Choose the tool around the work you do most. On-Screen Takeoff gives an estimator direct measurement tools, plan overlays, optional AI Takeoff Boost, and a path into Quick Bid. Portravo starts with an AI draft from a plan PDF, requires you to confirm each quantity, then prices confirmed lines with a dated reference basis.
Compare workflowsSTACK is built for plan management, direct digital takeoff, estimate worksheets, and team collaboration in a cloud workspace. Portravo is a narrower route from a plan PDF to one reviewed, priced estimate, with a required human check before each line is priced.
Compare workflowsUse one representative plan set and one real supplier quote. Compare how you correct quantities, trace the price basis, handle plan revisions, and export the estimate. Keep unsupported trades and the time spent building your library in the decision.
Portravo gives you a sample project at signup. Its Sacramento material figures are dated reference benchmarks, not live supplier quotes. Other supported metros use a labeled regional index. Confirm procurement pricing before a bid leaves your desk.
