What they did
Keep invoices in one Google Sheet, connect Sheets and Gmail, and have the bot draft polite reminders for overdue ones. An auto-review rule makes every external email wait for your yes; reminders get firmer each round and are logged in the sheet.
Result (as claimed)
Saved as an "invoice chaser" skill on a Monday 9am routine.
Tools they used
Cost: Grok Bot: from $30/mo.
Set it up
Gather the documents
Collect statements, bills, invoices or tax documents for the period you want reviewed.
Ask for an audit, not actions
Have Grok Bot list findings, amounts and suggested next steps before it does anything.
Approve each action
Approve cancellations, disputes or payments one at a time. Never give an agent open-ended access to move money.
Track the result
Record what changed and what you saved so you can check it next month. This is not financial advice.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
