Artificial QA fixtures
日本 sample invoice files
These files are intentionally simple, clearly marked test data. They support parser, arithmetic, error handling and UI tests; they are not official authority samples or submission-ready invoices.
Test scenarios to add to your own suite
- Valid invoice, credit note, cancellation and correction
- Missing mandatory party or routing identifier
- Tax rounding, multiple rates, exemptions and reverse charge
- Duplicate submission, retry after timeout and webhook replay
- Deprecated schema version and invalid code-list value
- Readable rendering compared with the structured source
