FEC fields (Fichier des Écritures Comptables)

AI-generated content

This document was generated by an AI assistant from the 'Event Matrix Accounting' Google Sheet. Verify accuracy before relying on the details.

The FEC (Fichier des Écritures Comptables) is the format imposed by the French tax authority for any export of accounting entries during a tax audit. ADB's accounting events all carry these 19 fields; some are mandatory (the regulator requires them), some are optional but populated.

How this maps to events

The sheet's "Events × FEC matrix" tab marks, per event, which of these 19 fields is populated. The vast majority of events populate every TRUE row; the pending ones (Lettering, JE n°) are still being shaped — see the open questions below.

Open questions

  • JE n° (field 3) — the source flags it as "À clarifier". The ADB sequence service exists (accounting_sequence collection in adb-accounting) but it's not clear whether it follows the strict "continuous numbering" rule the FEC requires. Worth a focused review.
  • Lettering (fields 14–15) — flagged as "Pending" in the source. ADB doesn't expose a manual lettering UI today; the regulator accepts blank values as long as the sequence is auditable.
