Prompts for Freelancers: From Quote to Unpaid Invoice

The client writes: "Just a small tweak, it should take you two minutes." You know it's half a day, outside the quote. You also know your answer is going to set the tone for the rest of the engagement. That's where AI does you a favor as a freelancer, far more than writing your bio: it helps you at the moments when you're alone making the call, with no colleague to ask for an opinion.

Here's a set of prompts, organized along the course of an engagement. Before using them, check your contract: many include a confidentiality clause. Replace the client's name and sensitive data with neutral terms, and read your tool's terms.

Before signing: read a brief like a wary partner

A vague brief quickly becomes a project that goes off the rails. Rather than rushing into the proposal, first have it look for what's missing.

Prompt

I'm a [FREELANCE PROFESSION], and I just received this brief (client name removed):
[PASTE THE BRIEF]

My usual terms: [DAY RATE OR FLAT FEE, AVAILABILITY, WHAT I DON'T DO]

Analyze this brief the way a cautious partner would:
1. What is explicitly requested.
2. What is implied and could cost me unpaid time (revisions, meetings, content to be supplied, sign-off by several people).
3. The warning signs, quoting the relevant sentence.
4. The 5 questions to ask the client before pricing, ranked by impact on the price.

Don't give me a price: I'll do the pricing myself. If part of the brief is too vague to conclude, say so.

A writer will notice that "a few articles" gives neither the number nor the pace. A developer will see that "simple admin interface" can hide a whole permissions system. The most valuable result is often the list of questions, which shows the client you understood their need. It all depends on the context you give the AI: your usual terms, in particular, change the reading.

Write a proposal centered on the client's problem

A proposal generated in one go usually opens with your background and ends up a catalog. Flip the logic.

Prompt

Client's answers to my questions: [ANSWERS]
Problem they want to solve, in their words: [QUOTE OR SUMMARY]
What I'm offering: [DELIVERABLES, STEPS, TIMELINES]
Price: [PRICE AND TERMS]
Real proof I can cite: [AUTHORIZED SIMILAR PROJECT, OTHERWISE "NONE"]

Write a proposal of 300 words maximum, in this order:
1. What I understood of the situation, in 3 sentences, without flattery.
2. What I'll do, deliverable by deliverable, with a number of revisions included.
3. What isn't included.
4. Schedule and what I need from them.
5. Price and next step, in one sentence.

No "passionate," no "tailor-made solution," and no reference or result I haven't given you.

The "what isn't included" part will serve you the day the small tweak arrives. If the tone doesn't sound like you, don't throw it all out: fix one point at a time, as explained in our guide to iterating.

Respond to an out-of-scope request without damaging the relationship

Back to our "small tweak." The bad reflex is to do it for free, with resentment building up. The weak prompt gives you a text that apologizes three times:

Prompt

Politely tell my client this isn't included in the quote.

The useful version puts the decision in their hands:

Prompt

My client is asking me for this: [REQUEST, IN THEIR WORDS]
What the signed quote says: [EXCERPT]
Estimated actual time: [DURATION]
Price for this extra: [AMOUNT]
Relationship: [E.G.: GOOD CLIENT, SECOND ENGAGEMENT]

Write a reply of 80 words maximum, friendly and without apology, that:
- welcomes the request
- explains in one sentence that it falls outside the planned scope, without citing the contract aggressively
- gives the cost and the timeline
- offers two options: add it now or save it for a later phase

End with a question that calls for a simple answer.

Offering two options changes the tone of the exchange: you're not refusing anything, the client chooses. Keep this message in your library of reusable templates, it will come back.

Prepare for a negotiation by being pushed around

Before a call where the client will haggle over your rate, practice. The AI can play the difficult counterpart, and stumbling in front of it costs nothing.

Prompt

You're playing [CLIENT'S ROLE, E.G.: MARKETING DIRECTOR AT A SMALL BUSINESS], who finds my quote too expensive. She has a limited budget and is hesitating with a cheaper competitor.

My offer: [SUMMARY AND PRICE]
What I can give up: [SCOPE, PAYMENT SCHEDULE]
What I won't give up: [FLOOR, TERMS]

Raise one objection at a time and wait for my answer. Be realistic and a little tough, without caricature. After 5 exchanges, drop the role and tell me where I gave in too fast, where I talked too much, and what I could have asked for in return.

What you'll mostly hear are your own reflexes, like lowering your price before anyone has asked. The floor, for its part, has to come from your own calculations: the AI knows neither your expenses nor your status, and your accountant will be a better guide if you need to work it out.

Chase an unpaid invoice in stages

Between businesses in France, a late payment in principle triggers penalties and a fixed €40 fee for recovery costs, which must be stated in your terms of sale and on your invoices. Check yours. With a private individual as the client, the rules differ, and for a disputed case, talk to a legal professional.

Prompt

Invoice no. [NUMBER], amount [AMOUNT], overdue by [NUMBER] days.
Client: business, relationship [GOOD / STRAINED].
Terms on my invoice: [EXCERPT: PENALTIES, FEE]
Previous exchanges: [SUMMARY]

Write 3 messages:
1. Reminder that the due date has passed: short, no blame, treating it as a possible oversight, with the invoice attached.
2. Firm follow-up, one to two weeks later: precise deadline, reminder of the terms above.
3. Last message before formal action: factual, no threats or legal exaggeration, announcing the next step, which is [FORMAL NOTICE (MISE EN DEMEURE), MEDIATION].

Don't invent any legal reference or procedure. Use only the terms I've given you.
