ContractorCounter - 2026 Pricing, Features, Reviews & Alternatives

ContractorCounter is a browser-based solution for construction drawing markup and quantity takeoff that enables contractors, estimators and construction reviewers to annotate PDF documents, perform calibrated measurements and organize plan sets without desktop installation. The platform is designed for preconstruction teams requiring fast access to measurement and annotation tools for residential, commercial and infrastructure projects. Users can upload PDF plan sets into structured folder hierarchies to group sheets by project or phase and return to the exact drawing location when needed. The interface supports standard annotation tools such as text boxes, callouts, arrows, highlights, revision clouds and custom stamps applied directly to the PDF layer.

The calibration system allows users to establish scale from a known dimension on the drawing and obtain real world measurement results for linear dimensions, perimeters, areas and volume estimates. The count tool enables placement of numbered markers that can be grouped, split or merged as scope definitions evolve and the resulting counts flow directly into a bill of quantities feature. Measurement and count edits update live numerical values when geometry is adjusted. Markup layers, calibrated measurements and quantity data persist within the workspace and can be exported as clean PDF documents and structured quantity lists.

ContractorCounter operates entirely within the browser and stores all drawing files and markup data in a secure cloud environment accessible from any modern web browser. The platform does not replace estimating or project management systems and instead prepares more accurate quantity data for downstream pricing and proposal workflows. Advanced features include an AI assistant that interprets natural language requests to automate counts, takeoffs and quote generation. Collaborative workspaces support multiple users reviewing the same drawing sets and sharing comments within the platform. Enterprise deployments can leverage single sign on capabilities and dedicated onboarding support to meet organizational requirements.
