The problem it solves

Sorting through vendor invoices and receipts by hand eats up time you don't have, and it's easy to miss one buried in your inbox. Newsletters and spam mixed in with real bills make manual triage even messier.

Who it fits

Finance teams, freelancers, and operations managers who handle vendor invoices and expense receipts by email.

How it works

  1. A new email arrives in your invoice inbox
  2. AI checks whether it's a real financial transaction, ignoring newsletters and spam
  3. AI reads the invoice, whether it's a PDF attachment or text in the email, and pulls out the amount, vendor, and category
  4. The system checks the numbers for errors and assigns a spending category
  5. The record is added to Google Sheets and a confirmation email is sent, with errors logged separately
What you get

Invoice records ready for your approval

You get every vendor invoice and receipt read automatically, with the amount, vendor, and category logged to your spreadsheet and ready for your final approval.

What you get

A running, categorized log of invoices and receipts in Google Sheets, ready for approval.

What you need

A Gmail account, a Google Sheets account, and OpenAI and Google Gemini API access.

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.
