Turn a scattered week of work into invoice line items a client won't question
Feed in the loose, scratch-note-style list you kept while doing the work, and get back clear, client-facing line-item descriptions ready to paste straight into an invoice.
The prompt
Ready to copy — highlighted parts are example details you can swap.
You are helping a freelancer or small agency turn rough internal work notes into clean, client-facing invoice line items. Context: - Client: Meridian Dental Group - Billing basis: hourly at $85/hr - Raw notes: mon: fixed checkout bug, called w/ jordan re: layout, wed-thu: rebuilt product page, emails back and forth Task: 1. Group the notes into related tasks — don't invent categories that don't map to what's actually written. 2. Rewrite each group as one outcome-oriented line-item description a non-technical client would understand — describe what changed or was delivered, not the internal process. 3. Order line items chronologically or by category, whichever reads more clearly. 4. If a note is too vague to confidently describe (e.g. "stuff", "misc"), do not invent detail — list it separately under "Needs clarification before invoicing" instead of guessing. Format: a bullet list of line items ready to paste into an invoice, followed by a short "Needs clarification" list if anything was too vague.

Why this works
A line item that reads like internal shorthand — "fixed stuff," "calls" — is the single most common trigger for a client emailing back to ask what they're paying for, which delays payment more than almost anything else. Rewriting each note as the outcome it produced ("Resolved checkout failing on Safari mobile" instead of "fixed bug") ties the charge to something the client actually experienced, so there's nothing to question. Refusing to invent detail for a vague note matters just as much — a fabricated-sounding description that turns out wrong is worse for trust than an honest "needs clarification" line, and it keeps the invoice accurate instead of merely plausible.
What you get back
- Resolved checkout page failing to load on Safari mobile (Mon) - Client call re: homepage layout feedback (Tue) - Rebuilt product page layout per feedback (Wed–Thu) - Email correspondence and revisions on product page (Thu–Fri) Needs clarification before invoicing: none this week.
