On Center Software, commonly referred to as On Center, is a software company that develops construction estimating and digital takeoff tools. The firm's products are designed to help construction professionals measure, quantify, and price work directly from digital plans and drawings. The company serves general contractors, subcontractors, design-build teams, and suppliers who rely on efficient, accurate takeoffs and estimates to support bidding, budgeting, and project planning.

The flagship product is On-Screen Takeoff (OST), a digital takeoff solution that lets users view drawings on a computer screen, perform measurements, and markups, and export quantity data. Another core product is Quick Bid, an estimation application that enables users to assemble cost estimates, manage areas or assemblies, and produce bid-ready documents. The products are designed to integrate with common CAD, BIM, and spreadsheet workflows, and can exchange data with other estimating and project-management tools.

Delivery methods include desktop installations and cloud-enabled options, with features for collaboration, version control, and centralized project libraries. Users can create reusable takeoff templates, manage revisions, and generate reports to support bidding and project execution.

History and positioning: On Center Software established its niche in the construction software market in the 1990s and has since expanded its product line to address digital takeoff and estimation needs across various market segments. The company emphasizes training and customer support to help firms implement digital estimating workflows.
