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.

No surprises after the sale. ________________________________________ Calculate What Actually Matters Track the numbers that affect your take-home income: • Item price and shipping charged • Materials and packaging (flat or itemized) • Labor time and hourly rate • Marketplace and payment processing fees • Flat and per-item fees • Monthly overhead allocation • Equipment cost across its lifespan See exactly what you earn per product — not just revenue. ________________________________________ Built for Makers and Small Businesses Save products and compare margins across your catalog. Duplicate pricing scenarios to test adjustments in seconds. Archive, organize, and refine your pricing as your business grows. Whether you sell online or in person, True Margin helps you make informed pricing decisions. ________________________________________ Designed to Respect Your Work • One-time purchase • No subscriptions • No accounts required • All data stored locally on your device ________________________________________ True Margin Basic is not a budgeting app. It’s a focused pricing tool for people who want to run their business intentionally. Price with clarity. Protect your profit.

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.
