## The problem

Monthly books close slowly because someone has to manually enter 200 receipts. Accountants charge for manual data entry that a computer can do. Mistakes happen at 4pm on the 30th of the month. Receipts get lost; expenses go uncategorized.

## The outcome

Every receipt or invoice hitting a shared inbox (or dropped into a shared folder) gets parsed: vendor, date, amount, category, tax, currency. Clean rows go to QuickBooks/Xero/Notion. Anomalies (amount > threshold, unknown vendor, duplicate) get flagged for human review before auto-posting.

## Why [IronClaw](https://openclawdatabase.com/ironclaw/)

Financial data + strict audit log = IronClaw. Every extraction is logged with source, model used, confidence score. If something's wrong, you can trace it. For regulated businesses, this trail is mandatory.

### Alternatives worth considering

- **[OpenClaw](https://openclawdatabase.com/openclaw/)** — For small businesses where audit requirements are lighter — faster to set up
- **[Hermes](https://openclawdatabase.com/hermes/)** — If you want the agent to also remember vendor patterns over time and improve categorization accuracy

## Setup steps

1. ### Step 1: Set up the inbound channel

 A dedicated email (receipts@your-domain) or a shared Dropbox folder. Don't pipe your regular inbox — agents and financial data need isolation.
2. ### Step 2: Configure the extraction schema

 Vendor, date, total, line items, tax, currency, category. Categories match your chart of accounts. Explicit schema means the output plugs straight into bookkeeping without reformatting.
3. ### Step 3: Add the anomaly rules

 Flag: amount over [threshold], vendor never seen, duplicate (same vendor + amount + date), foreign currency, missing tax field. Flagged items go to a human queue.
4. ### Step 4: Integrate with your bookkeeping tool

 QuickBooks/Xero/FreshBooks/Notion all have APIs. Clean rows auto-post; flagged rows sit in a queue until approved.
5. ### Step 5: Add monthly reconciliation

 End of month, the agent pulls the bank statement, matches each transaction to a processed receipt, flags any unmatched. You only look at the exceptions.

## Example prompt

```
Extract from this receipt: vendor, date, total, line items with amounts, tax, currency, suggested category from [chart of accounts]. Output a confidence score 0–1. If confidence < 0.8, flag for human review with a specific reason.
```

## Pitfalls to avoid

- **Trusting OCR on low-quality photos.** A crumpled receipt photo at 2pm after lunch yields garbage. Have the agent output a confidence score; below threshold → human review.
- **Auto-categorizing everything.** Categories matter for tax time. A misclassified 'meals' vs 'entertainment' can cause audit issues. Auto-categorize confident matches; defer ambiguous ones.
- **Not testing the recovery path.** If the agent fails for a week, can you catch up manually? Build in a weekly 'show me what hasn't been processed' report.

## Cost breakdown (monthly)

| Item | Cost |
| --- | --- |
| Model API (vision + text) | $10–40 |
| IronClaw hosting | $0 |
| Bookkeeping tool integration | $0–20 |

Total: **$15–60/month**. Costs assume typical usage; heavy use can run higher.
