Scope Change Order Generator

Turn a client's 'small extra request' into a clear change order with the added price, the new delivery date and an approve button, before you start the work.

Economics

Pricing example
$19 lifetime (free version adds a small footer credit)
Daily math
1 sale a day x $19 = $19/day; about 32 sales a month averages $20/day.
Target if you hit the daily math
Target: $550 - $800 / month if the daily math is hit

Audience and urgency

Audience: Freelance designers, developers, video editors, copywriters and small agencies working on fixed-scope projects.

Urgency: Extra requests arrive mid-project in chat messages. Without a short written change with a price and a date, freelancers either do the work unpaid or have an awkward money conversation at invoice time.

MVP scope

  • ✓ Project profile: client, original scope summary, hourly or day rate, currency, original delivery date
  • ✓ Change form: paste the client's request; optional AI helper rewrites it into clear scope bullets that the freelancer edits
  • ✓ Pricing by hours x rate or fixed price per item, plus the new delivery date and payment terms
  • ✓ Share link with an 'Approve change' button that records the client's typed name and a timestamp, plus a PDF copy
  • ✓ Change log per project with a running total of approved extras; Stripe Payment Link removes the footer credit

Omitted features

  • - Do NOT present the document as a legal contract or give legal advice
  • - Do NOT collect payments or build invoicing in Day 1
  • - Do NOT build project management, tasks or time tracking

One-shot master prompt

Build a "Change Order Generator" web app in React with Tailwind CSS and Supabase.
Core requirements:
1. Projects: client name and email, original scope summary, rate type (hourly/day/fixed), rate, currency, original delivery date. Store in Supabase with magic-link auth.
2. New change order: textarea for the client's request plus an optional "Tidy into bullets" button calling an LLM; the user edits the bullets. Add line items as hours x rate or fixed price, a new delivery date, and payment terms (e.g. 50% before start).
3. Live A4 preview showing original vs new totals and dates; export to PDF.
4. Public share link /co/[random-id] (noindex) where the client types their name and clicks "Approve change"; store name, timestamp and IP and show an "Approved" stamp on both the page and the PDF.
5. Project change log with running totals of approved and pending extras. Free version adds a footer credit; a Stripe Payment Link ($19) unlocks removal via a licence code.
