The problem it solves

Chasing down which invoices still need to go out, writing a polite email for each one, and then updating your records afterward eats up time you could spend on client work. It is easy to lose track of who has actually been billed.

Who it fits

Freelancers, agencies, or small businesses that bill multiple clients regularly.

How it works

  1. Pending invoices are pulled from a spreadsheet
  2. AI drafts a professional email for each client
  3. A formatted PDF invoice is generated
  4. The email and PDF are sent to the client through Gmail
  5. The spreadsheet is updated to mark the invoice as completed
What you get

Invoice emails drafted and PDFs attached automatically

Your clients receive a polished invoice email with a formatted PDF attached, and your records update the moment it's sent.

What you get

A sent invoice email with a PDF attachment for each client, and an updated billing record.

What you need

A Google Sheets account, an OpenAI account, a Gmail account, and a CraftMyPDF account.

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.
