KNTRCTR is web-based subcontractor management software for heavy civil and general contractors. Prime contractors can post job dates, scope, requirements and attachments once for invited crews, then compare and level bids while retaining the original bid for reference. Rex AI scans bids for outliers, unanswered items and past reviews, and can read attachments before an award. It presents analysis rather than selecting a subcontractor; the user makes the award decision. Invited subcontractors can open jobs, ask questions and submit bids for free. After an award, a shared job workspace supports contacts, insurance details and a checklist. Performance reviews stay double-blind until both parties submit them. KNTRCTR works alongside existing estimating and project management systems, but is focused on organizing bids and tracking subcontractor performance rather than takeoffs, scheduling or cost control. The first prime-contractor seat is 250.00 USD per month, with the first 30 days free; extra seats are 50.00 USD per month. Invited bidders have a free plan.
