Construction takeoff software (sometimes spelled take-off or take off) is a collection of programs, processes and information used to perform a part of the cost estimating process in the construction industry. Estimators use construction blueprints, either manual or electronic, and start "taking off" quantities of items they will need from those blueprints in order to prepare part of the estimate. Examples of possible takeoffs include the number of light fixtures needed in a building or the amount of wiring needed for electrical work.

Takeoff can happen several ways. Some estimators perform manual takeoffs from field sketches, some conduct on-screen take offs using construction estimating software programs, and some use digitizers, which are electronic measuring devices that work on hard copy plans. Once takeoffs are on screen, measurements and calculations can be done automatically, increasing accuracy, efficiency and speed.

Takeoff software typically allows downloading of many different file types, including TIFF, PDF, DWF Adobe, JPEG and most CAD (computer-aided design) documents.
