About

TradeOff is cloud-based software for takeoff, estimating, and progress billing that streamlines workflows from blueprint analysis to client payment. The platform enables users to upload PDF drawings directly into their browser, where scale calibration, trace, and count tools simplify quantity aggregation. An AI assistant enhances this process by extracting quantities, detecting scales, and suggesting rates. The estimating matrix provides a spreadsheet-style grid for pricing, while progress billing features support schedule-of-values billing, retainage tracking, and tax compliance like CIS deductions and VAT reverse charges. Payment processing is supported through Stripe and BACS, complemented by team collaboration roles and one-click PDF exports for branded estimates and payment applications.

Pros & Cons from Real Users

Pros

  • As an old school QS/Estimator, who was brought up on using paper drawings and take-off sheets, this has been mind blowing. I have been using a free on line take-off system, that has no back up and will eventually be taken down, together with my own take -off and estimating Excel spreadsheets. I love the ability to screen shot my mark ups and add them to my take-offs for future reference. I have seen others using Bluebeam and I would consider Purple Hammer to be above and beyond this system. The ability to compare drawing revisions is a great feature. We all know the architects who like to push out drawing revisions and not actually cloud the revisions.

Cons

  • The only con at the moment is my own limits. I'm looking forward to Ari Isaacs showing me how to incorporate my own take-off sheets. Looking forward to being able to exploit it's features
