The problem it solves

Your finance inbox fills up with invoices and receipts that someone has to open, read, and manually enter into a spreadsheet. Mistakes creep in, categorization is inconsistent, and it takes real time away from higher-value work.

Who it fits

Small business finance teams and bookkeepers managing invoices by email.

How it works

A new invoice or receipt email arrives
AI checks whether it is actually finance-related before proceeding
AI reads the email and pulls out vendor, amount, date, and tax details
The details are checked for errors and sorted into an expense category
The invoice is logged as a new row in your Google Sheet

What you get

An up-to-date expense ledger in Google Sheets with every invoice logged and categorized.

What you need

A Gmail account 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.
