Chase unpaid client invoices with AI, for accountants

Unpaid invoices sit on your ledger while you dread typing out awkward reminder emails between client meetings. AI reads your aging report and drafts calm, polite notes matched to how late each bill is.

What to gather first

Your current accounts receivable aging report
Three past reminder emails that worked
Your standard payment terms and link

Which app

For this one, a plain AI chat window is enough: ChatGPT, Claude, or Gemini. Open the chat, paste what you gathered, and type the message below. First time? Read how to talk to an AI.

How to do it

Export the aging report. Download your current receivables as a clean text file or table. Strip out tax numbers and personal phone lines. Leave the client names, dates, amounts, and notes on current work.
Paste the prompt and data. Open your AI chat window and paste the prompt below. Add your report and the examples of your normal firm voice right after it. Send the message.
Review the sorted drafts. AI sorts the clients by how long the balance has stood. It writes a gentle nudge for recent dates and a firmer check-in for older balances. Read every draft against your knowledge of the client relationship.
Copy and send from your inbox. Adjust any fee details or personal pleasantries that need your human touch. Paste the text into your email and send it yourself. Mark your ledger with the follow-up date.

What to type first

Here is our accounts receivable report and three reminder emails I wrote in the past. Group these unpaid clients by how late they are. Draft a separate reminder email for each one, using my firm's calm tone. Keep recent ones light and older ones clear about pauses on work. Do not send anything.

Change the words to match your business. AI follows what you say, so say what done looks like.

Before you trust it

Check that the dollar amounts match your billing software exactly.
Verify that the client is not currently waiting on a deliverable from your team.
Confirm that your direct payment link is included in each draft.
