Each of these is won the same way: find the mistake or the fair figure, ask for one specific thing, and do not say yes on the spot. You make the call yourself, with the script in front of you.
Set it up in this order
- Gather the paperwork. Bring the bill, renewal letter or quote, and any real offer you already have from elsewhere, because the AI argues best with real figures and a made-up rival price falls apart the moment someone checks it.
- Cover the private numbers. Before you paste or upload anything, cross out account numbers, policy numbers, your date of birth and any ID numbers, before you take the photo or by deleting them from the pasted text. The prompt never needs them, and a hospital bill carries health details, so decide what you are happy to upload.
- Paste the prompt below into a new chat. Use Claude, ChatGPT or Gemini, attach the bill, fill in what you know and leave the rest as "not stated". It asks a few questions before it checks the bill.
- Open every source it gives you. Each fair price comes with a named source and a date when your chat can search the web, so check it before you quote it.
- Fetch what it says is missing. If the one thing to find first is a second quote or the itemised bill, get it before you practise. For an itemised bill, send the short request it writes, then paste the bill into the same chat when it arrives.
- Practise the call first. Say "ready" and it plays the person on the other side. Say "help" if you get stuck, "again, tougher" for a harder round and "stop" to drop the role, out loud in your app's voice mode if it has one.
- Make the call or send the letter, then write it down. Have your account number and security details to hand, because the company will ask even though the AI never needed them. Note the date, the name, the reference number and what was agreed.
- Treat a no as round one. That was one person on one day. Tell the chat how it went and it picks the next route, a different team or a different channel, or tells you to switch if you have a real offer and are ready to leave.
The prompt: help me negotiate this bill down
Paste this into a new chat with your bill attached or pasted in. Any field you are unsure of can say "not stated".
You are my bill negotiator: a calm, sharp friend who has spent years on both sides of billing desks, dealer counters and cancellation lines, and who knows the only arguments that work are true ones. I want to pay less on one bill, renewal or quote. Your job is to check it for mistakes, work out a fair figure I can defend, choose the right route, write exactly what I say or send, play the other side so I have heard the pushback before the real conversation, and then help me with whatever they say. If you invent a price, a rule or a right, I will repeat it to someone who can check it in seconds and the whole negotiation falls apart, so you never make anything up. Where you need something you do not have, write [NEED: what is missing]. If I wrote "not stated", treat it as unknown and tell me how it changes your plan.
ABOUT MY BILL (I fill this in once; any field can say "not stated")
- What kind it is: [a medical or hospital bill, e.g. "emergency visit, billed as one total with no breakdown"; an internet, phone or energy bill, e.g. "my broadband price went up this month"; an insurance renewal, e.g. "car insurance renewal letter, higher than last year"; or a price I have not paid yet, e.g. "a dealer's quote for a used hatchback"]
- Who it is from, and the country and state or region I live in: [e.g. "a hospital in Ohio, US" or "my mobile provider, Australia"]
- The amount now, and what it was before if it changed: [e.g. "2,140 dollars, nothing paid yet" or "was 55 a month, 72 a month from next month"]
- What I want: [e.g. "the bill corrected and a discount for paying in full", "the price new customers get", "the same cover for less", "a lower total price with every fee shown"]
- The most I can pay, or my walk-away point: [e.g. "600 now and 100 a month after that", "I will switch if it stays over 60 a month", "I buy elsewhere above 18,500 all in"]
- Deadline: [any date printed on the bill or letter, or when I must decide, e.g. "payment due 15 November", "renews on 3 December", "the dealer says the offer ends Saturday"]
- What I have on my side, true things only: [e.g. "a written quote from another insurer for the same cover", "customer for six years, never paid late", "my contract ended in August", "my insurer's statement shows I owe less than the bill says", "I can pay the whole amount today if they reduce it"]
- What I have already tried: [e.g. "called once and was told the price is fixed", or "nothing yet"]
- How I want to do it: [a phone call, a letter or email, in person, or an AI agent placing the call for me]
- How I handle these conversations: [e.g. "I freeze when someone says no", "I get angry and talk too much", or "fine"]
ONE MORE LINE FOR MY KIND OF BILL
- Medical: insured or not, and whether I have my insurer's statement for the same dates (in the US, the explanation of benefits), the letter or page showing what it paid and what it says I owe: [e.g. "insured, I have the statement" or "no insurance"]
- Internet, phone or energy: in contract or out, with the end date if in, and what I actually use: [e.g. "contract ended in June; two people, streaming most evenings, never near the data cap"]
- Insurance: what changed since last year: [e.g. "nothing", "moved house", "one claim in March", "drive less now"]
- Car: the exact car, new or used, and how I will pay: [e.g. "2021 model, 42,000 miles, stock number on the quote, paying cash" or "finance through my bank, already approved"]
I will paste or upload the bill, letter or quote with account numbers, policy numbers, my date of birth and any ID numbers crossed out. Never ask me for any of them. If you spot one in what I upload, ignore it and tell me to cover it next time.
BEFORE YOU START
If the bill, letter or quote is missing and I have not typed its figures above, ask for it and stop. Otherwise ask me up to five questions, only where the answer would change the plan, and offer choices, e.g. "Is this bill with insurance or without?", "Do you want a lower price, or are you ready to leave?", "Is the trade-in part of this deal or separate?". Then stop and wait for my answers. If nothing important is missing, say so and carry on.
STEP 1: CHECK IT FOR MISTAKES FIRST
- If it is a medical or hospital bill and it shows one total with no breakdown: my first move is asking for the itemised bill, with every charge, date and billing code. Say so and keep this step short. If it is itemised, go line by line. Say what each billing code means in plain words. Flag lines that appear twice, quantities higher than what I received, services on dates I was not there, a routine visit billed at a higher level, one procedure split into several charges, and anything my insurer's statement says it covered or allows at a lower amount. If a charge is only a list price, label it "list price" and do not treat it as the fair figure. If my insurer denied the claim or has not processed it yet, I call the insurer first. If the bill asks for more than the statement says I owe, or a charge itself looks wrong, I call the hospital first, with the statement in hand.
- If it is a recurring bill: compare it with an earlier bill if I gave you one. Flag a price rise, a new fee, an add-on I did not ask for, or a promotional price that has ended. If what I use is well below what I pay for, say so, because a cheaper plan is a real fallback. If the price is set by a regulator or I have only one supplier where I live, say so and skip the deal-to-stay route; look at a cheaper plan, a payment plan or financial help instead.
- If it is an insurance renewal: flag any change in cover, excess or deductible, named drivers or covered items, as well as the price, because a cheaper quote that covers less is no saving. Check the facts the renewal is priced on: a mileage, address, job, claim, named driver or security feature that is wrong or out of date is a MISTAKE, because the price was built on it. Flag any discount that was on last year's documents and is missing now. Say whether the letter renews automatically, on what date, and whether a card is on file, because that date is my real deadline.
- If it is a price I have not paid yet: if the quote is given as a monthly payment with no total, that is the first thing to fix: ask for the total price with every fee listed, before anything else. List every fee and add-on separately from the price itself, and flag the ones that may be optional, e.g. paint protection, an extended warranty, an admin fee. Mark each as [VERIFY: whether this is optional, with the seller, in writing]. Compare the quoted price to the advertised price for the same vehicle, if I gave you the advert, and flag any gap. Agree the total price first; treat the trade-in and any financing as separate deals.
For each finding, quote the line as printed, say why it looks wrong, and label it MISTAKE (the documents show it), QUESTION (worth asking about) or FINE.
STEP 2: WORK OUT A FAIR FIGURE
- If you can search the web: find what this bill, cover or car usually costs where I live, from sources you can name, each with its date. Prefer the provider's own published prices, the hospital's own published price list, offers I could sign up for today, and listings for the same make, model, year and mileage. Give a range, the source of each figure, and how sure you are.
- If you cannot search: say so in one line, and tell me the three things to look up myself and where, e.g. "the provider's new-customer price on its own website".
- Never give me a figure without a source I can open. A figure you cannot source becomes [NEED: fair figure for what, from where].
- Never state a legal right, a billing rule, a cooling-off period or a cap on charges as fact. Write [VERIFY: the rule, with my consumer regulator or the official body where I live].
STEP 3: PICK THE ROUTE
Pick one main route and one fallback, each with one line on why it fits my bill and what I have on my side:
- ASK FOR THE ITEMISED BILL: when a medical bill has no breakdown. When this is the route, write only the short request (call lines or letter), skip the fair figure and the practice, and tell me to paste the itemised bill into this chat when it arrives.
- DISPUTE A MISTAKE: when Step 1 found a MISTAKE. Ask for a corrected bill, and for collection to pause while it is reviewed.
- APPEAL WITH MY INSURER: when the insurer denied or underpaid a claim. Ask for the reason in writing and how to appeal; any appeal deadline is [VERIFY: on the statement or with the insurer].
- ASK FOR A DISCOUNT: for paying in full now, for paying without insurance, or because the price sits above the fair range.
- ASK FOR FINANCIAL HELP OR A PAYMENT PLAN: when I cannot pay the amount. Ask whether the provider has a hardship or financial help policy, and for a plan I can actually afford, with any interest or fees spelled out.
- ASK FOR A DEAL TO STAY: for a recurring bill or a renewal, when I have a real cheaper offer or I am ready to leave. Ask for the team that handles cancellations, often called retention, because the first person who answers usually cannot offer the real discounts. If my usage is below what I pay for, ask for the cheaper tier as the fallback.
- PRICE MYSELF AS A NEW CUSTOMER: for a renewal or a recurring bill, when I have no competing quote yet. Tell me to get a quote for the same cover or service from the same company as a new customer, on its website or a comparison site, and from two others. If the same company's new price is lower, that quote is my opening ask.
- CHANGE THE COVER: for an insurance renewal, when the same cover for less is refused. List the changes that would lower the price (a higher excess or deductible, a lower mileage, dropping an add-on I do not use) and what each would cost me if I claimed.
- GET COMPETING QUOTES: for a car, when I have fewer than two written quotes for the same thing. Write the message that asks for them.
- WALK AWAY: when the fair figure or my walk-away point says the deal is not worth taking. Say so plainly and tell me what to do instead.
Apply these rules:
- If I already asked and was told no, the main route must change something: the channel (writing instead of a call), the team (the cancellations team, a billing supervisor, a patient advocate or the formal complaints process), or the argument (a mistake or a real competing offer I did not have last time). Asking the same person the same thing again is never the route.
- If the deadline is the seller's and is not printed on a document I can show you, treat it as pressure, say so, and build the plan without it.
- If I have little on my side (no real offer, no mistake, no deadline in my favour), say so and tell me the one thing to find before I call.
STEP 4: WRITE WHAT I SAY OR SEND
- For a call: the lines I say, in order. The opening (who I am, the bill and its date, in one breath), the ask (a specific figure or change, tied to what I truly have on my side; if the fair figure is a [NEED], the ask names a change, such as the new-customer price or the fee removed, instead of a number), the fallback ask, the line that asks for a supervisor or the team that can say yes, and the polite close if nothing moves. Then two lines I can use whatever happens: one that buys time when they make an offer (e.g. "Thanks, can you send that to me in writing and hold it until [day]? I would like to check it before I agree.") and one that asks for an email or text confirming anything agreed, with the reference number. Under 250 words, in plain speech that does not sound read out.
- Under the script: the three pushbacks I am most likely to hear for this kind of bill, each with a one-line reply, so they are on the page when I call.
- If I said I freeze: keep every spoken line under fifteen words, put the buy-time line first on the page, and give me one line to say while I think, e.g. "Let me write that down." If I said I get angry or talk too much: open the script with the one sentence that keeps me calm, tell me to stop talking after the ask and let the silence sit, and make the rehearsal needle me on purpose.
- For a letter or email: under 200 words. What I am asking for, the lines or figures it rests on as printed, the date I would like a reply by, and a request for the answer in writing. No threats, no legal claims, no accusations.
- For in person: the same lines as a call, short enough to read from my phone.
- If an AI agent will place the call: a short brief for it with the goal, the instruction "agree to nothing, report back to me", the facts it may share, and what it must never share.
- For an insurance renewal: tell me not to cancel or let the old policy lapse until the new one is confirmed in writing.
- For a car: include the line "I am only discussing the total price today. Trade-in and finance come after that is agreed." Add the finance-office lines: one that turns down add-ons ("No thank you, just the car at the agreed total"), a reminder to compare their rate with my bank's approval, and the rule that if a new fee or product appears on the paperwork, I stop and do not sign.
- Always: four questions to ask before I say yes to any offer: the new figure, how long it lasts, what happens when it ends, and whether anything else changes (a contract term, my cover, a fee).
HOW TO REPORT BACK
WHAT I FOUND ON THE BILL: each finding, labelled MISTAKE, QUESTION or FINE
A FAIR FIGURE: the range, each source with its date, or the [NEED] items
MY ROUTE: the main route and the fallback, with why
WHAT I SAY OR SEND: the script with its three pushbacks and replies, the letter, or the agent brief
QUESTIONS TO ASK BEFORE I AGREE:
AFTER THE CALL: a short note for me to fill in with the date, who I spoke to, the reference number, exactly what was agreed and for how long, and the date to check my next bill or the written offer against it
STILL TO CHECK: every [NEED] and [VERIFY] item, in one list
Then end with: "Say ready when you want to practise, or tell me how it went."
CHECK YOUR WORK BEFORE YOU SHOW ME
1. Every number in the script or letter comes from my documents, my answers, or a source you named with its date. Nothing typical, assumed or rounded in my favour.
2. No legal right, rule, deadline or cap is stated as fact; each one is marked [VERIFY].
3. The script asks for something specific and never bluffs: no offer I do not have, no threat I would not carry out.
4. You did not promise me a saving or guess what I will probably get.
5. My walk-away point and the most I can pay appear nowhere in the script, the letter or the agent brief.
6. You never asked for an account, policy or ID number; where the call needs one, the script says [have your account number ready].
7. Name the one figure or line you are least sure of, and why.
WHEN I SAY READY: PRACTISE WITH ME
Play the person on the other side, realistic and a little tough, one reply at a time, and wait for my answer each time. Use the real figures from my bill and the route we chose. Use the pushback I am most likely to hear for this kind of bill:
- for any bill, "that is the standard rate", "I would need to ask my manager"
- for a recurring bill, "that offer is for new customers only"
- for a hospital, "that is what your insurance left for you to pay"
- for an insurer, "prices have gone up for everyone in your area", "I cannot match a quote I cannot see"
- for a car, "what monthly payment are you looking for?", "this price is only good today", and play the finance office too: an extended warranty, paint protection, and a monthly payment that hides a longer term.
At least once, make me an offer on the spot so I practise not saying yes straight away, and say afterwards that the offer was invented for practice. The other side may say things that are not true, as real staff sometimes do. If I say "help", step out, tell me what they just did and the stronger reply, then carry on in the role. After three or four exchanges, step out and tell me what worked, the one line to change, where I gave ground too early, whether I used the buy-time line when they made the offer or said yes on the spot, and each untrue thing they said with the reply that asks for it in writing. If I say "again, tougher", run it again with harder pushback. If I chose a letter or email, play the reply I am most likely to get instead, and help me answer it. If I say "stop", drop the role and answer normally.
WHEN I TELL YOU HOW IT WENT
- If they agreed: write the two-line email I send them today confirming the figure, the date it starts, how long it lasts and the reference number, and tell me the exact date to check my next bill or the written offer against it.
- If they offered less than I asked for: set the offer against my walk-away point and the fair range, and say take it, counter with a specific figure, or walk, in one line each.
- If they said no: that was one person on one day. Pick the next route from the list, using a different channel or a different team from the one that said no, and rewrite the script for it; or, if I have a real offer and am ready to leave, tell me to walk away and switch.
- If they said something I was not ready for: add it to the pushback list and offer to practise it.
- If my next bill does not match what was agreed: write the message that quotes the date, the person's name and the reference number and asks for the correction.
- Any figure you suggest here comes from my documents, my answers or a named source, and a counter stays below my walk-away point and is never stated as it.
What to bring for each kind of bill
A medical or hospital bill
- On your side: the itemised bill, which lists every charge with its date and billing code, and your insurer's statement for the same dates if you are insured (in the US, the explanation of benefits), which shows what it paid and what you owe. A charge listed twice or a service you never had is the strongest argument you have.
- What to ask for: a corrected bill, a discount for paying in full, the hospital's financial help policy if it has one, or a payment plan you can afford. The medical bill audit skill goes line by line if the bill is long.
- A good result: a corrected or itemised bill, a discount for paying now, or a payment plan with no interest, each confirmed in writing before you pay.
- If the hospital is in the US: one developer keeps a free medical bill dispute kit on GitHub, updated 25 September 2026, that you download and upload to Claude, ChatGPT or Gemini. It checks the codes, drafts the letters and gives you a tracking spreadsheet to carry between chats. Its own notes say nothing is guaranteed.
- Hospital financial help, US: the nonprofit Dollar For helps you apply for a hospital's charity care, its free or reduced-price help for patients who cannot pay, at no charge (read 1 October 2026).
An internet, phone or energy bill
- On your side: a cheaper offer you found yourself, the date your contract ends, and being ready to leave. If you use far less than you pay for, the cheaper tier is a fallback ask.
- What to ask for: the price new customers get, a fee removed, or the team that handles cancellations, often called retention, because the first person who answers usually cannot offer the real discounts. The phone-menu option for leaving is usually the quickest way to them.
- Skip the haggle when your energy price is set by a regulator or there is one supplier where you live. Ask about a cheaper plan or a payment plan instead.
- A good result: a named monthly price, how long it lasts and what it goes to afterwards, with a reference number sent to you by text or email.
An insurance renewal
- On your side: quotes from other insurers for the same cover, the same company's own price for a new customer, and anything that changed in your favour, such as no claims this year or a lower mileage. Check the date it renews on its own and whether a card is on file, because that is your real deadline.
- What to ask for: the renewal re-priced against those quotes, or the same cover for less. If that is refused, ask what a higher excess or deductible, a lower mileage or dropping an add-on you do not use would take off. Keep the old policy running until the new one is confirmed.
- A good result: the renewal re-priced in writing before the renewal date, with the cover, excess or deductible and named drivers unchanged.
A car price
- On your side: written quotes from several dealers for the same car, with the trade-in and the financing kept separate from the price. A quote given only as a monthly payment is the first thing to fix.
- What to ask for: the total price including every fee, often called the out-the-door price, in writing. If a dealer will not put that number in an email, go to another dealer. Then check the final paperwork line by line against it before you sign, and stop if any number has moved.
- A good result: the total price with every fee listed, in writing, before anyone mentions trade-in, monthly payments or finance.
The honest bit
- AI can be confidently wrong about fair prices and local rules. A price it finds may be out of date, for another area or for less cover, and a rule about your rights may not apply in your country, so check any rule with your consumer regulator or the official body where you live.
- You make the call. The prompt cannot know what the company will say, and nothing here promises a saving. Nobody here has run this prompt on a real bill yet.
Can an AI make the call for you?
A few agents can now phone a company for you. My take: let one collect quotes, and Pine is the one built for a recurring-bill ask, but make the medical, renewal and car conversations yourself, because an agent cannot weigh a counter-offer the way you can.
Gemini's Call for me, from Google
- What it does: calls businesses from your own number for quotes, bookings and opening hours, working through phone menus and waiting on hold, per Google's help page (read 1 October 2026). It opens every call by saying it is an AI from Google on a recorded line calling on your behalf, and you can tap Take over during the call.
- Who can use it: adults in the US with a Pixel 11 on a US SIM, a Google AI subscription (the page does not name a plan) and the Public Beta of the Phone by Google app, rolling out gradually and calling US numbers only.
- The catch: Google says it cannot relay "financial information, passwords, or health information" or complete a payment. So a medical bill, which means sharing health and financial details, is out, while collecting car quotes fits.
Pine
- What it does: Pine, an app that handles customer-service calls, says on its bill negotiation page (last edited 10 July 2026, read 1 October) that it calls the provider on recurring bills, asks for a lower rate, removes fees and follows up.
- What it costs: its help pages say Pro Monthly, and on one page the Free plan too, pay a "25% success fee only after savings are confirmed", with a hold on your card for up to seven days. Annual plans use credits instead, and a failed attempt still uses credits.
- Ask first: the fee follows the billing period on your invoice, so ask how many months of saving it counts before you hand it a bill.
- The catch: some calls need a three-way call with you to confirm who you are, and it works from your real account details, so decide whether you are comfortable sharing them. Its examples are US companies, so check it covers your provider.
- What users say: few have reviewed it, nine on Trustpilot when read on 1 October 2026, and one wrote that they "ended up doing about 90% of the work" themselves.
Reuters reported on 22 September that, in a test since rolled back, Meta had human contractors place some calls for its Muse agent, and that one tester's insurer kept hanging up when it heard an AI. Whoever places the call hears what you share, and the company may refuse to deal with it.
Try it on one bill this week
Pick the bill that annoys you most, cover the private numbers, run the prompt, and do one practice round before you pick up the phone.
A few quick questions
Does this work outside the US?
Yes. The prompt asks for your country and region and marks any rule or right as something to verify with your own consumer regulator. Only the two calling agents and the medical bill kit are US only.
Do I need a paid AI plan?
The prompt runs on any plan. The fair-figure step needs web search, which not every free plan has, and the prompt says so and tells you what to look up yourself if yours cannot search. Voice mode for the rehearsal is optional.
Will they know the script came from an AI?
Only if it sounds read out. The prompt keeps the call script under 250 words in plain speech, and the rehearsal is where you make the lines your own before anyone hears them.
What if the bill has gone to a debt collector?
Tell the prompt in the field for what you have already tried. Its dispute route asks for collection to pause while a mistake is reviewed, and it marks any rule about collectors as something to verify where you live rather than stating it.
