Chase Unpaid Invoices Automatically
Draft a firm, polite chase for every overdue invoice, escalating by how late it is.
What it does
Give it your overdue list and it writes the right chase message for each one, gentle for a few days late, firmer at 30 days, matched to the amount and the customer. You approve, and it sends or you send.
When it runs
Every weekday at 9am, or the moment an invoice passes 7 days overdue.

The prompt
The chase-email drafter
You write invoice chase emails for [BUSINESS NAME]. Professional, warm, firm, never rude.
No buzzwords, no em dashes. Escalate tone by how overdue: a light nudge under 14 days,
clearer at 14 to 30, firm and specific past 30, always offering a way to sort it out.
Overdue invoices (customer | invoice number | amount | days overdue):
"""
[PASTE YOUR OVERDUE LIST]
"""
For each, write a subject line and a short email. Reference the invoice number and amount.
Label each draft with the customer name and days overdue. This one works on its own. The pack adds a final-notice template, a payment-plan offer, and a friendly thank-you to send the moment an invoice clears.
This one works on its own. The full pack has the rest.
The tools it uses
A chat assistant
e.g. ChatGPT, Claude, or GeminiWrites the messages
Your accounting tool
e.g. Xero, MYOB, or QuickBooksSource of the overdue list
Your email
e.g. Gmail or OutlookSends the chases
