Invoice and late-payment wording

Chasing money is awkward for most tutors. You like the families. You don't want to sound like a bank. An AI tool can help you strike a friendly tone, as long as it never makes up the terms.

Set your terms before you ask

The tool doesn't know your payment rules. It will invent them if you leave a gap. So decide the following, in your own words, before any draft.

• What you charge, and in which currency.
• When payment is due: before the lesson, on the day, at month end or within some number of days.
• How people can pay.
• What happens if they don't, such as pausing lessons.
• Whether you charge anything extra for late payment.

If you don't charge a late fee, say so to the tool and don't let it add one. A late fee you never announced is a poor surprise for a parent.

A prompt for the first invoice note

Write two friendly sentences to go with an invoice. The amount is AMOUNT in CURRENCY. It is due DATE. Payment methods: METHODS. Add no other terms, fees or deadlines.

That is the whole job. The invoice itself should come from your own invoicing tool or template. Keep the numbers in the invoice, not only in the chat message.

The reminder, step by step

Start kind, and only move to firm if you have to.

• First reminder. Assume a slip. "Just a quick note in case this got buried."
• Second reminder. Restate the amount and the due date and ask for a reply.
• Third message. Say what happens next, using only a step you've already told families about.

Ask the tool for a version at each level, then pick. Here is a prompt for the first one:

Write a short, friendly reminder that an invoice is unpaid. Don't blame. Mention the amount and due date I give you below. Don't add late fees or threats.

Don't let the tool invent terms

Chatbots can state false things as though they were fact¹. In a payment reminder, that can be an interest charge, a final-notice date or a mention of "debt recovery". None of that should appear unless you've set it.

Strike any sentence about fees, interest, collections or legal action. Keep it only if you chose it and know the rule behind it.

Tax invoices: check the official page

Some countries require a particular kind of invoice in some situations. In Australia, the tax office has a rule on this. If a customer asks, you must provide a tax invoice within 28 days, unless the sale is $82.50 (including GST) or less². That page was checked on 31 October 2026, and the amounts can change.

Whether this applies to you depends on your registration and on what you sell. Ask the ATO, or your own tax authority, and don't rely on an AI tool for tax advice.

Business customers are a different case

Some tutors invoice a school or a company, not a parent. In the UK, the government says you can claim interest and debt recovery costs if another business is late paying³. That page is about businesses invoicing other businesses.

It also covers what happens when no date is agreed. The payment is then late 30 days after the customer gets the invoice, or after you deliver the service if that's later³.

A parent paying for a child's lessons is usually a private customer, so read the page carefully before you assume it fits. If you aren't sure, ask an adviser or the government page itself. Other countries have their own rules.

Keep the tone steady

Money messages go wrong when they swing from sweet to stern. Keep the same voice at each stage, and keep the facts plain: what was billed, the date it was due, how to pay.

Don't mention pausing lessons in the first reminder. If you plan to pause for non-payment, put it in your terms early and in writing.
