Automatically read invoices, route them for approval, and log the data

Reads invoices from email, Drive, or a form, extracts the details with AI, and routes them for approval before logging.

How the work actually flows

It branches. Exactly one path is taken; a person has to approve before it continues.

The problem it solves

You or your finance team spend hours retyping invoice details from PDFs into a spreadsheet, and invoices arrive from too many places to track consistently. Without a clear approval step, mistakes and duplicate payments slip through.

Who it fits

A finance team or small business that processes invoices from multiple sources and needs an approval trail.

How it works

An invoice arrives by email, is uploaded to Drive, or is submitted through a form
AI reads the PDF and extracts the vendor, amount, and due date
The invoice is categorized and sent for email-based approval
Approved invoices are logged in a spreadsheet, and rejections notify your finance team

What you get

A spreadsheet record of every invoice with its category, approval status, and reviewer notes.

What you need

A Google Workspace account (Drive, Gmail, Sheets) and an OpenAI API key.

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.
