The module reads your Dolibarr invoices and calculates, to the cent, your CERFA 3310-CA3 return. You review, you file.

Your day-to-day transactions are allocated to the correct CERFA CA3 boxes from your actual accounting data — invoices and general ledger —, with French tax rules applied automatically.
Collected and deductible VAT calculated by cross-referencing your invoices with the accounting allocation in the general ledger, multi-rate (20%, 10%, 5.5%, 2.1%, DOM 8.5%).
Intra-community acquisitions of goods and non-EU services (art. 283-2), collected/deductible neutrality by design.
Exports, non-taxable transactions, and the OSS scheme for intra-EU B2C distance sales.
Twelve consistency rules checked and blocking before validation: filing an inconsistent return is impossible.
The VAT credit is carried forward automatically from one quarter to the next — no more forgotten line 22.
A value entered “as filed”? The module detects it, asks for a reason and keeps it: dedicated block in the return sheet and in the PDF.
Tracking of gaps between calculated and filed values with the time bar (art. 208), plus adjusting journal entries proposed and reversible, including the 19/20 reclassification and non-deductible VAT.
Lodging expenses carrying VAT, restaurant receipts entered entirely at 20%: flagged without ever blocking, acknowledged in one click.
Generation of a PDF reproducing the full return sheet, plus quarterly and annual dashboards.
No figure pulled from a black box: every amount comes from your actually validated invoices and their accounting allocation in the general ledger (accounts that were actually posted to). The module uses only the entries that matter, applies the CERFA rules, and lets you review and justify every line before filing.
