What the alternative costsThe alternative is writing the reminder yourself or using a bookkeeping service; no price for either alternative is supplied in the available tool data.

If this goes wrong: the customer receives an inaccurate or overly forceful message, which you can usually correct with a prompt apology and the right invoice details.

What to actually do

  1. Do it yourself

    The route this page recommends

    A chat interface, no skill needed, and roughly 15 minutes until you can act on the result.

    How to actually do it

    1. Open the invoice and your accounting or bookkeeping records for the customer.
    2. Gather the customer name, invoice reference, exact amount, invoice date, due date, payment terms, payment method and contact details.
    3. Paste those facts into the prompt and ask the chatbot to produce the reminder.
    4. Compare the draft line by line with the invoice and accounting records, correcting every amount, date, reference and payment instruction before sending.
    5. Send the checked message from your normal business email and record the reminder in your credit-control notes.

    Prompt

    Write a friendly UK business payment reminder email using only the facts below. Do not invent or alter any amount, date, invoice reference, payment method, bank detail, contractual term or consequence. Keep the tone polite and assume this may be an honest oversight. Do not threaten legal action, add late-payment charges or make legal claims. State the invoice reference, amount due, original due date and how the customer can pay. Ask the customer to confirm if payment has already been made and give a neutral contact route for questions. Use plain British English, a concise subject line and an email of no more than 150 words.

Customer name: [customer name]
Invoice reference: [invoice reference]
Amount due: [amount and currency]
Invoice date: [invoice date]
Due date: [due date]
Payment terms: [payment terms]
Payment method or link: [payment method or link]
Contact name and contact details: [contact details]
Preferred tone, if different: [tone]

    Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

  2. Use a tool built for this

    Second choice

  3. Hand it to a person

    The distant third

    A person who owns the outcome does this end to end, worth it when the failure is dear.

What it gets wrong

  • AI cannot know whether the customer has already paid unless you provide current accounting records.
  • AI cannot decide whether this customer needs a gentle nudge, a firmer escalation or a phone call based on your trading relationship.
  • AI cannot apply your credit-control policy or check whether a late-payment charge is permitted by your contract.
  • AI cannot take responsibility for an incorrect amount, recipient or payment instruction.

Even on a YES, the friction has a name: relationship and judgement under ambiguity.

FAQ

Can ChatGPT write a payment reminder email?
Yes. Give it the invoice facts and a clear tone instruction, then check every figure and date against your records before sending.
How do I write a polite overdue invoice reminder?
State the invoice reference, amount and due date, ask whether payment has already been made, and provide a straightforward way to pay or ask questions. Keep the first message neutral and do not add threats or charges that you have not checked.
Can AI chase unpaid invoices for me?
AI can draft the messages and help organise a repeatable process, but it cannot safely decide when to escalate or know whether a payment has arrived without current records. You still need to check and send each message.
Is it safe to use AI for credit control?
It is suitable for drafting routine reminders when you remove unnecessary personal data and verify the details against your records. It is not professional advice, and a serious dispute or threatened legal action needs advice from a solicitor or accountant.
