Basis (estimate): Your own estimate: writing terms from scratch vs reviewing an AI draft. The bigger saving is unmeasured: disputes you never have. Not measured.
What does this setup do?
Draft clear payment terms: deposits, due dates, late fees, and project-stall rules
Who is it for?
A freelancer or small business owner who has been burned by vague payment agreements
How do you set it up?
Tools
- ChatGPT or Claude (free tier works)
- How you currently bill: project, hourly, retainer, milestones
Steps
- Write down how you bill today: when you invoice, when you expect payment, what goes wrong.
- Paste the prompt below with your details.
- The AI drafts payment terms covering deposit, due date, late fees, and paused projects.
- Read every line. Delete anything you would not enforce. Terms you will not enforce are worse than no terms.
- Check late-fee rules for your state. Some states cap them or restrict surcharges.
- Put the final terms on your quotes, your contracts, and your invoices. All three.
- When a client pushes back, negotiate scope or timing, not the existence of terms.
Example output
Illustrative. Your results will differ.
- This week's invoices: 4 sent, 2 paid, 2 overdue
- Reminder drafts ready for the overdue ones
- You approve each reminder before it sends.

Draft payment terms for my business. I am a [FREELANCER / CONTRACTOR / SERVICE BUSINESS] doing [TYPE OF WORK]. I bill [per project / hourly / monthly retainer]. My typical invoice is $[AMOUNT]. Write payment terms covering: 1) deposit required before work starts, 2) when the balance is due, 3) late fee for overdue payments, 4) what happens if the client pauses the project mid-way, 5) what happens if the client cancels. Keep the language plain and professional, no legalese. Note anywhere I should check local law.Newsletter

What usually goes wrong?
Where agents tend to stall on this job. More patterns in Where AI gets stuck.
- The AI writes terms you would never enforce. If you will not charge the late fee, do not list it.
- Late-fee caps vary by state. What is fine in one state may be restricted in another. Check yours.
- Putting terms only in the contract and not on the invoice. The invoice is what the client actually reads.
- Treating AI-drafted terms as legal advice. For big contracts, get a real review.

Common questions
- What is the difference between Net 30 and "due in 30 days"?
- Net 30 is the formal accounting term. "Due in 30 days" means roughly the same but is clearer to clients. Clarity gets paid faster, so use plain words.
- Should I offer an early payment discount?
- A small one, like 2 percent for payment within 10 days, can pull payments in weeks early. Do the math first: on a $5,000 invoice, 2 percent costs you $100 to get paid a month sooner.
- Can I add a late fee to an existing client?
- For new work, yes, with notice. For invoices already sent under old terms, no. Update your terms going forward and tell clients when they change.
What tips make it smoother?
- Shorter terms get paid faster. Try 7 or 14 days instead of the default 30.
- Write "due in 14 days" instead of "Net 14". Plain words get paid sooner.
- A 50 percent deposit on project work is standard and filters out unserious clients.
- State the late fee on the invoice, not just the contract. Clients read invoices.
