Stop building contractor estimates in scattered spreadsheets, handwritten notes, and disconnected proposal templates. Create professional project bids, calculate labor and material costs, apply taxes and discounts, manage bid history, track pipeline status, and generate polished proposal documents with one secure, fully offline contractor estimating system.
For contractors, builders, remodelers, and construction service providers, preparing accurate bids is one of the most important—and time-consuming—parts of winning profitable work. Every project requires careful cost breakdowns across labor, materials, phases, taxes, discounts, and margin targets. A small pricing mistake can wipe out profit, while an unprofessional proposal can cost you the job entirely.
The Contractor Bid Generator is a professional Single Page Application (SPA) designed for general contractors, renovation companies, subcontractors, estimators, and construction business owners who need a practical all-in-one system for preparing bids, managing project estimates, and generating professional client proposals. It combines a dynamic cost engine, work breakdown structure builder, bid history dashboard, client pipeline tracker, company profile settings, PDF proposal generation, Excel export, and local database backup tools into one streamlined contractor workspace.
Instead of jumping between spreadsheets, Word documents, calculators, and CRM notes, this tool gives you a single operational command center where you can build estimates phase by phase, calculate taxes and discounts in real time, save project bids, update statuses, and issue polished proposal documents with confidence.
Best of all, it runs 100% offline in your browser. No SaaS subscription, no monthly fees, and no risk of sensitive project pricing, client records, or internal cost structures being uploaded to third-party servers. Your contractor estimates, CRM records, proposal settings, and cost catalogs stay stored locally in your browser—giving you full ownership of your commercial data.
