What they did

Who chases unpaid invoices when you don't have time? Instead of chasing them or hiring someone, this small company built a billing agent, gave it its own email address and put it to work. Two past-due invoices were paid the day after one reminder. They say it's one of about 46 agents running their company.

How it went

Polite reminders sent on schedule and a weekly list of what's still unpaid.

Worth knowing

  • Short post; the company sells tech and process consulting, but the post describes its own use and pitches nothing. Two invoices is a small sample.

Prompt

Cleaned version rewritten from the source — not a direct quote.

You're our billing assistant, using your own email address [address]. Every Monday, check [invoices / accounting tool] for anything past due. Send each client a short, polite reminder with the invoice number, amount, due date and how to pay. If they reply with a question, forward it to me. Never threaten, add fees or change amounts without my approval. Send me a weekly list of what's still unpaid.

Ask your bot for a security review of an email that passed every check

An email from [email protected] landed in a Tesla engineer's inbox. It passed SPF, DKIM and DMARC (the checks that confirm who sent an email) and showed the blue check, but something felt off, so he asked his Grok Bot to do a security review. It found a hidden phishing link, explained why every safety check had passed, and wrote a report to xAI with a proposed fix. He then had it add a security routine that checks his email for anything phishy going forward.
