Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.

States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.

Differentiate and validate

Hypothesis: Contractors need faster repeat invoices more than more templates.

First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.

The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.

Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

App Store description

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. Why contractors use Subdex Organize subcontractors by trade and specialty Keep all subcontractor contact information in one place Quickly find electricians, plumbers, roofers, painters, tile installers, carpenters, framers, and other trades Build a cleaner and more searchable construction contact list Reduce chaos across jobs, estimates, and project coordination Save time when hiring, calling, texting, or checking your subcontractor network Create a more professional system for managing trade partners Subdex is ideal for general contractors, home remodelers, construction managers, builders, handymen, renovation companies, project managers, and small construction businesses that want a faster way to manage subcontractors and trade contacts. Whether you are running kitchen remodels, bathroom renovations, deck builds, additions, basement finishing, roofing jobs, siding projects, or full home renovations, Subdex helps you stay organized and in control. Use Subdex to manage: Subcontractor contacts Trade partner lists Construction crews Specialty contractors Vendor and installer relationships Jobsite communication Contractor networking Trade directories Construction operations contacts Simple, fast, and contractor-focused Subdex is built to be easy to use in the office, at home, or on the jobsite. The interface is clean, modern, and made for speed so you can open the app, find the trade you need, and keep moving. No bloated CRM setup. No confusing features. Just a focused subcontractor management tool built for construction. As Subdex grows, it is designed to become even more useful for contractors by supporting stronger organization, better communication, and expanded subcontractor workflow management. The goal is simple: help general contractors manage their subcontractors more efficiently and create a stronger system for running jobs.

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
