## If something goes wrong

| Symptom | Lead |
|---------|------|
| Accountant rejects invoice | Wrong SIRET, MINIMUM profile instead of EN 16931 |
| PDF VAT ≠ XML | WC per-line rounding, regenerate Factur-X |
| ETI client receives nothing | Check **PDP** deposit, not email alone |
| Numbering gaps | Tests on staging only |
