The problem it solves

Every receipt your team collects means someone has to type the vendor, date, amount, and tax into your books by hand. That manual entry is slow, error-prone, and easy to fall behind on when receipts pile up.

Who it fits

Small business owners, bookkeepers, or field staff who need receipts logged without manual data entry.

How it works

  1. You send a photo or PDF of a receipt over WhatsApp
  2. The system reads the document with high-accuracy OCR
  3. AI extracts the vendor, date, amount, and tax details
  4. The receipt image is saved to Google Drive and the details are logged in Google Sheets
  5. You get a WhatsApp reply with the extracted details to confirm or correct
What you get

Receipts logged without typing them in yourself

You get receipts read from WhatsApp photos, logged into your spreadsheet, and saved to Drive, ready for you to confirm.

What you get

A logged spreadsheet row for each receipt, plus a stored copy of the original file.

What you need

A WhatsApp Business account, a LlamaParse account, an AI API key, and a Google Workspace 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.
