Process Summary
- Capture — Receive invoice (email attachment, photo, direct PDF). Copy to
inbox/. - Extract — OCR if needed, parse fields (provider, date, amounts, tax).
- Validate — Check required fields, detect duplicates.
- Organize — Rename, move to
archive/YYYY/MM/, updateentries.json. - 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
- Unusual amount (>50% higher than same provider average)
- Missing expected recurring invoice
