Trust the Takeoff

If you are a pro at manual takeoff, On-Screen Takeoff (OST) will seem natural to you. It’s construction estimating software that thinks the way you do, only faster. It calculates everything you need for your estimates on your computer screen with a few clicks and drags of a mouse. OST automatically saves your takeoff calculations for quick access to incoming change orders, and a headstart on your next bid.

Reduce errors and rework

Rework eats up to 20% of the cost of the average construction project. On-Screen Takeoff is swift and accurate and automatically saves your takeoff calculations for incoming addendums before bid day, change orders and revised specs on the job, and gives you a head start on your next bid. It gives you detailed backup on changes to scope, which helps eliminate warranty claims.

Key Features

Auto-Count Objects, Annotations, and Callouts

Optical Character Recognition (OCR). This feature allows you to count out objects of the same shape and size within the drawings. If you have to take off 125 studs on a wall, and you have a room with four walls, OST will auto-count the studs.

Intelligent Paste Logic

Selects takeoff objects and pastes them into a similar distance, space, and directions. This feature is a huge time-saver for ceilings, and multi-room takeoff, with the same layouts such as hotels, apartments, condos, and dorms.

Multi-Condition Takeoff

You can select any number of conditions and draw the takeoff once. On-Screen Takeoff places the appropriate takeoff objects on the plan, automatically, all at the same time!

No Paper. Point, Click, & Drag

Walls, doors, sidings, windows and more. You name it, and OST can take it off. Our software has some time-saving takeoff tools and setup options that will save you lots of time. OST has some of the most advanced takeoff options on the market.


Save multiple hours of exhausting plan review with the overlay feature. When comparing two versions of a drawing, deleted items are in red, and added items are in blue.

Style Sheets & Templates

Streamline project setup by creating typical takeoff conditions called “styles.” Combine styles into sets to quickly drop in multiple conditions to your bid.
