Real use case

Hand off the monthly admin for a rental

The poster says keeping up with the admin for his rental, like bank transactions and utility invoices, used to need a coding agent and screen-scraping scripts. Now he says ChatGPT Work handles much of it, including running it on a schedule.

Copy this prompt

On the [DAY] of every month, go through the utility invoices in [FOLDER OR EMAIL LABEL] and the bank export I save to [FOLDER]. Match each invoice to its payment, and list any unpaid invoice, any payment without an invoice and any bill more than [10]% higher than last month. Put it in a table in [SHEET NAME]. Don't pay or email anyone.

Our own prompt, written from what the source describes. We haven't run it ourselves. Text in [BRACKETS] is what you replace.
