Shoebox: a small model reads your receipts overnight, slowly, and never guesses a number

Description and use

Shoebox automatically processes receipt photos overnight, verifies arithmetic, files them, and produces a daily expense summary.

Problem

Freelancers and small‑business owners spend hours manually entering receipts into spreadsheets.

Outcome

In a test month, Shoebox filed 7 receipts, flagged 3 for review, and reported a total spend of 756,127 in the expense sheet.

Workflow

• Photograph receipts and drop photos into Shoebox/Inbox
• Every night at 2 AM Shoebox runs on the local machine
• Gemma 4 copies all printed lines, totals, discounts, taxes, cash paid and change
• Shoebox performs arithmetic checks to confirm totals
• If all checks pass, rename and file receipt under month/category and update monthly expense sheet
• If checks fail, move receipt to Check me/ with discrepancy notes
• Generate Good morning.txt with filing summary
• Allow user to query results via shoebox ask command

Evidence

Shoebox reads the new ones on your own computer with Gemma 4, checks each one's arithmetic, files it by month and category with a sensible name, and writes the month's expense sheet.

Source

Filed 7 receipts overnight; 3 would not add up and wait in “Check me”. This month so far: 756,127 (Books/expenses-2026-10.csv).

Source

The arithmetic decides whether to believe it. A receipt is filed only when its total is confirmed by other figures printed on the same receipt.
