Track expenses in Google Sheets and get AI spending alerts by email

Reads your expense spreadsheet, sorts spending into categories, and emails you an AI-written summary when costs run high.

How the work actually flows

It branches. Every path runs; runs once per each expense row.

The problem it solves

You know your expenses are piling up in a spreadsheet, but nobody has time to sit down and categorize every line or spot the month you overspent. By the time you notice a budget problem, the money is already gone.

Who it fits

A freelancer, small business owner, or household that already tracks expenses in Google Sheets.

How it works

  1. New or updated expense rows are read from your spreadsheet
  2. Each expense is automatically sorted into a category like food, transport, or subscriptions
  3. Spending per category is totaled and checked against your budget limit
  4. AI writes a plain-English financial summary and advice
  5. You get an email alert, flagged high or normal, with results saved to a second sheet
What you get

Spending summaries that flag high-cost months

You get a plain-English summary of your spending by category, with an alert whenever costs run higher than your budget.

What you get

An updated spreadsheet of categorized spending plus an email report with AI financial advice.

What you need

A Google Workspace account (Sheets and Gmail) and a Google Gemini 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.
