Quick Reference

Process Summary

1. Capture — Receive invoice (email attachment, photo, direct PDF). Copy to inbox/.
2. Extract — OCR if needed, parse fields (provider, date, amounts, tax).
3. Validate — Check required fields, detect duplicates.
4. Organize — Rename, move to archive/YYYY/MM/, update entries.json.
5. Confirm — Show extracted data, allow corrections.

See process.md for detailed workflow.

Critical Rules

• Never delete originals — Keep PDFs permanently. Legal requirement (4-6 years depending on country).
• Detect duplicates — Same invoice number + provider = duplicate. Alert, don't overwrite.
• Validate tax math — Base + tax should equal total. Flag discrepancies.
• Provider normalization — "HETZNER ONLINE GMBH" = "Hetzner". Maintain provider aliases.

Alerts

• Invoice pending >48h in inbox
• Payment due in <7 days
