AutoACCT — Bookkeeping Skill for Claude Code

English | 简体中文

A Claude Code skill that turns a receipt image (optionally with a caption) into a structured row in a Google Sheet, with automatic HKD conversion.

Intended to be invoked manually inside Claude Code today, and wired up to a WhatsApp webhook later.

What it does

1. Reads a receipt / invoice / payment-screenshot image via vision.
2. Extracts: date, merchant, category, amount, currency, payment method, line items, raw OCR, caption note.
3. Converts the amount to HKD at that day's ECB reference rate via frankfurter.app (free, no API key).
4. Appends one row to a configured Google Sheet (14 columns — see schema.md).
5. Replies with the row and flags any field it had to guess.

Install

Clone into your Claude Code skills directory:

git clone https://git.deepknow.site/Knowit/AutoACCT.git ~/.claude/skills/bookkeeping

Then follow scripts/setup.md for the one-time setup:

• Python deps: pip install google-api-python-client google-auth
• Create a GCP service account + download its JSON key
• Create a Google Sheet, add 14 header columns, share with the service account email
• cp config.example.json config.json and fill in sheet_id + service_account_path

Use

In a Claude Code session, drop a receipt image in and say "log this" (or similar). The skill auto-triggers on receipt-image requests — no slash command needed.

Caption is optional; use it to add context (payment method, split, category hint, free-text note).

Files

File	Purpose
SKILL.md	Entry — Claude reads this to invoke the skill
categories.md	Fixed category list (14 categories)
schema.md	Google Sheet column order (A–N)
config.example.json	Template → copy to config.json (gitignored)
scripts/fx_convert.py	Currency → HKD via frankfurter.app
scripts/append_row.py	Writes one row to Google Sheets
scripts/setup.md	One-time setup steps

Roadmap

• WhatsApp webhook layer (Meta Cloud API or Twilio) so images can be sent from a phone.
• Optional Google Drive upload so the Receipt column becomes a clickable image link.
• Monthly summary script (totals by category, currency breakdown).
