CostLogic is browser-based construction takeoff and estimating software that helps contractors measure plans, create estimates, and manage invoices in one connected workflow. Users can upload construction PDF plans, navigate multi-page drawings, calibrate or automatically detect scale, and perform linear, area, count, angle, and polyline measurements directly on the plans.

The platform includes Auto Room for detecting rooms and areas, along with Onyx, an integrated AI assistant that can answer questions about projects, organize takeoff layers, and draft estimates. Measured quantities flow into line-item estimates with controls for markup, waste, tax, and deposits, reducing the need for manual data entry.

CostLogic also supports construction invoicing by converting approved estimates into invoices, sending branded PDF documents by email, maintaining customer records, and recording payments. Designed to run in a web browser without desktop installation, it provides tools for digital takeoffs, construction estimating, job costing, and invoice management from plan measurement through billing.
