States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.

Subdex is the subcontractor management app built for general contractors, builders, remodelers, and construction professionals who need a better way to organize subcontractors, trade contacts, and crew communication. Whether you manage residential remodeling, commercial construction, renovations, additions, roofing, plumbing, electrical, carpentry, tile, painting, drywall, flooring, masonry, HVAC, or finish work, Subdex helps you keep your subcontractor network organized and easy to access. General contractors often rely on scattered phone contacts, text threads, notes apps, spreadsheets, and memory to keep track of subcontractors. Subdex gives you one clean place to manage subcontractor contacts by trade, specialty, and working relationship so you can quickly find the right subcontractor for the right job. Instead of digging through your phone or losing track of who does what, you can organize your construction contacts in a simple system designed specifically for the way contractors work. Built for contractors Subdex is not a generic CRM. It is a contractor app designed for real construction workflows. Organize subcontractors by tags such as electrical, plumbing, roofing, finish work, tile and flooring, doors and windows, painting, carpentry, drywall, framing, masonry, excavation, concrete, HVAC, siding, landscaping, demolition, cleaning, and more. This makes it easier to search, sort, and manage your subcontractor list when pricing jobs, staffing projects, or finding trusted trades on short notice. Designed for general contractors If you are a general contractor managing multiple subcontractors across multiple jobs, Subdex helps you stay organized without adding complexity. Use it as your subcontractor directory, trade contact manager, construction phonebook, subcontractor organizer, and relationship management tool. Keep your crew network structured so you can move faster, communicate better, and reduce missed opportunities.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
