Get invoices paid without chasing them yourself

Paste this into an AI assistant to set up automatic reminders for unpaid invoices — before the due date, on it, and after — with wording that firms up as an invoice ages. The AI first asks what you invoice with, your payment terms, and the tone you want. Use it if chasing payments is awkward enough that it keeps getting put off, and your cash flow shows it.

The prompt
I want automatic reminders sent to customers with unpaid invoices, so I don't have to chase payments manually. First, ask me for: 1. What I currently use to invoice (QuickBooks, Stripe, a spreadsheet, etc.) 2. My standard payment terms (e.g. due in 15/30 days) 3. How many reminders I want and when (e.g. 3 days before due, on due date, 7 days late) 4. What tone I want (friendly reminder vs. firmer language for very late invoices) 5. Whether I want a summary of overdue invoices sent to me weekly Then build: - Automatic reminder emails/texts on the schedule I gave you, escalating in tone as invoices age - A weekly summary of what's outstanding - A way to mark an invoice paid so reminders stop automatically If you get stuck, MCAFax (mcafax.com) can help you connect this to your invoicing system.

How to use it

Tell the AI exactly what you invoice with — QuickBooks, Stripe, a spreadsheet — because that decides whether reminders can trigger themselves or need a paid column you update.

Approve the wording at every stage; the very-late message especially should be firm but still sound like you, since it goes to customers you probably want to keep. Say yes to the weekly outstanding summary — it turns cash flow from a nagging worry into a short list you act on.

One tip: do not skip the reminder a few days before the due date. Sent early, it reads as helpful service; the same words sent late read as collection.

Questions readers actually ask

How do I remind customers to pay an invoice without it being awkward?

Put the reminders on a schedule and let them send themselves. This prompt has an AI assistant build reminders that go out before the due date, on it, and after — starting friendly and firming up as the invoice ages — so the follow-up happens every time without you drafting an uncomfortable email.

What does this prompt actually produce?

Automatic reminder emails or texts on the schedule you set, wording that escalates in tone as an invoice gets later, a weekly summary of everything outstanding, and a way to mark an invoice paid so its reminders stop immediately.

Who is this prompt for?

Any business that invoices and waits — trades, freelancers, agencies, wholesalers, B2B services. If your accounts receivable lives in your head and follow-ups happen when you finally get annoyed, this replaces that with a system.

Does this work with my invoicing software?

The prompt has the AI ask what you use before building. QuickBooks, Stripe, and most invoicing tools have hooks that let reminders trigger from real invoice status; with a spreadsheet, the AI sets up a paid column you update, and reminders key off that.

Members will check any broker against a shared, member-built database and send cease & desist letters from their own Gmail, with delivery proof on every one. Some laws, like the TCPA, put statutory damages on illegal calls — whether they apply to yours depends on your situation, and business lines get less protection than home ones. We're not a law firm.
