Data & AnalyticsAdvanced★ 2,580⑂ 198AI score 9/10Last updated: Nov 5, 2026

What it does

Reproduces the work of a French commissaire aux comptes across seven sequential phases.

  • Mandatory intake: company identity (SIREN, legal form, tax regime), the audited fiscal year, and the list of available documents — missing critical facts are asked for, never assumed (can auto-load company.json)
  • Phases 1–7: planning and materiality thresholds → FEC ledger-file conformity (18 pipe-separated columns, debit/credit balance, sequence, dates, PCG account roots) → balance sheet → income statement → trial balance and general ledger → tax return forms (2033-A/B/C/D/E, 2572-SD) → bank reconciliation, cut-off, regulated agreements, subsequent events
  • Cross-checks accounts against bundled open data: data/pcg_YYYY.json (French chart of accounts) and data/nomenclature-liasse-fiscale.csv (tax-return boxes)
  • Outputs a report with an explicit opinion (unqualified / qualified / adverse / disclaimer), a per-phase ok–warning–fail table, observations, recommendations and the list of documents examined

Who it's for

  • Founders of French companies who want a dry run on their annual accounts before filing
  • Accountants and audit assistants working under French GAAP (PCG) and CNCC standards
  • Small SaaS businesses with deferred revenue (PCA) and payment-platform payout reconciliation issues

Examples

  1. "Check my 2024 FEC export" → flags column-format breaks, unbalanced entry numbers, out-of-period dates, non-PCG accounts
  2. "Reconcile the balance sheet, trial balance and form 2033-A" → line-by-line comparison with the exact differences
  3. "Draft the audit report" → qualified-opinion report with the per-phase summary table and remediation recommendations
