TradeOff
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.
