Change Order & Scope-Creep Documenter
Mid-job additions get a verbal 'sure, no problem' and then vanish — unbilled, undocumented, and disputed later.
You get
A written change-order draft the moment scope changes: what changed, what it costs, customer sign-off text.
- Who it's for
- Any trade where the job that was quoted isn't the job that gets done.
- When to use it
- The same hour a customer asks for 'one more thing.'
- What it needs
- What the customer asked to add or change
- Price and schedule impact (your numbers)
- Your Business Profile
- What it produces
- A change-order message with scope, price, and schedule impact, ready to send for confirmation.
- Files you receive
- Three formats, so it works with whatever you already use:
- Claude — Installable skill package (.zip). In Claude: Settings → Capabilities → Skills → Create skill → Upload a skill. Upload the ZIP without unzipping it, then turn the skill on.
- ChatGPT — Custom GPT instructions (.md). In ChatGPT: create a new Custom GPT, then paste the instructions file into the Instructions field.
- Universal — Copy-and-paste prompt (.md). Open the file, copy the whole thing, and paste it into a new chat with any AI assistant.
- Time to first result
- Recovers billable work that used to evaporate
The owner says
"While we're here she wants the hallway painted too. It's about $400 and half a day."
It hands back
A friendly change-order text confirming the hallway addition at $400 and the revised finish day, asking for a simple 'yes' before the crew starts it.
Illustrative example — not a customer result.
How it works
- 1Tell it what changed and your numbers
- 2It drafts the confirmation in your voice
- 3Customer replies yes in writing
- 4The addition makes it onto the invoice
Catches what is slipping
The verbal yes that would have become a billing dispute.

What gets flagged
- Any scope change without written confirmation → change-order draft
- Schedule impact > half a day → completion-date update included
You set the price and hit send. It makes the paper trail painless.
What you need to run it
You need an account with an AI assistant — Claude, ChatGPT, or another. Installing skills in Claude and creating Custom GPTs in ChatGPT both need those providers' paid plans; the copy-and-paste version works on any plan. See Anthropic's help center for what your plan includes. (Last verified 2026-08-02.)
