The problem it solves

Invoices land in your inbox alongside everything else and it's easy to lose track of what's due and when. Missing a due date can mean late fees or a strained relationship with a vendor.

Who it fits

Small business owners who get invoices by email and manage their own bill-paying.

How it works

  1. Runs on a schedule, checking your inbox hourly
  2. AI reviews each unread email to see if it's an invoice
  3. If it is, a reminder task is created in Google Tasks with the due date
  4. The email gets labeled and marked as read so you know it's handled
What you get

Late fees you avoid on vendor invoices

You get a reminder created automatically for every invoice that lands in your inbox, so due dates never slip through the cracks.

What you get

A Google Tasks reminder for every invoice you receive, with the payment due date attached.

What you need

A Gmail account, an OpenAI API key, and a Google Tasks account.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
