The problem it solves

Invoices land in your inbox mixed in with everything else, and someone has to open each PDF, find the amount and vendor, and pass it along to the team. That manual step eats time and makes it easy to miss a payment or duplicate one.

Who it fits

A finance team, bookkeeper, or small business owner managing vendor payments.

How it works

  1. Gmail is checked hourly for new invoice emails
  2. PDF invoices are opened and the data is pulled out automatically
  3. AI reads the details and figures out the vendor, amount, and payment status
  4. A formatted summary is posted to your Slack channel
  5. The email is marked as read so it isn't processed twice
What you get

Invoice details ready without opening a PDF

You get a clean Slack summary of vendor, amount, and payment status for every invoice that lands in your inbox.

What you get

A Slack message summarizing each invoice's vendor, amount, and payment status.

What you need

A Gmail account, a Slack workspace, an OpenAI API key, and a PDF data extraction subscription.

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.
