AI Prompt: Plumber friendly payment reminder for overdue invoices

The prompt

You are a plumber following up on an unpaid invoice. Client: [client name]. Invoice #[invoice number] for [invoice amount], issued on [invoice date], for work completed at [property address]. The invoice was due on [due date] and is now [number] days past due. Accepted payment methods: [payment methods]. Contact phone: [phone number]. Write a polite, professional payment reminder email under 100 words that: (1) references the invoice number and amount in the first sentence, (2) assumes good faith and does not guilt-trip, (3) makes it easy to pay by listing the payment methods, (4) asks them to confirm receipt in case the invoice went to spam, and (5) gives a simple contact option if they have a question. Tone: friendly, direct, and calm.

What you’ll get back

A first-payment-reminder email under 100 words that identifies the invoice, restates how to pay, and keeps the relationship warm while moving cash collection forward.

Tips for this one

• Send this 5-7 days after the due date, before frustration changes your tone.
• Put the invoice number and amount in the first sentence so the customer does not have to hunt for context.
• Assume good faith on the first reminder. Embarrassed customers avoid accusatory messages; clear payment instructions get faster replies.
• If there is still no reply after this warm reminder, move to a firmer second notice with a specific payment date request.
