Send invoices and chase late payments

“Clients pay late and I hate writing the reminder emails.”

AI can draft invoices from a template, keep a list of what's overdue, and write polite reminders that get firmer over time. You approve before anything goes out.

Fix it yourself in 3 steps

Keep one sheet of invoices: client, amount, sent date, due date, paid date.
Ask the AI to list what's overdue and draft a reminder for each, matched to how late it is.
Review and send yourself; mark paid ones as soon as money arrives.

Copy this prompt

Here's my invoice list: [sheet]. List every unpaid invoice past its due date, how many days late, and draft a reminder for each: friendly at 1–7 days, firmer at 8–30, final notice after 30. Include the invoice number and amount. Don't send anything — stop after the drafts.

Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
