What is a Factur-X type 386 deposit invoice?

Type 386 (Prepayment invoice) is the Factur-X code for a deposit invoice. It indicates that VAT is immediately due on the deposited amount, per CGI art. 289. Without this code, the deposit invoice is non-compliant with EN16931.

Is VAT calculated on the deposit amount or the total quote?

VAT only applies to the invoiced deposit amount (30%, 50% or fixed). It is immediately due on the invoice date. Residual VAT on the balance will be calculated in the balance invoice.

Can I create a deposit invoice without a quote?

Yes. By passing invoice_type: 'deposit' in invoices.create, you create a standalone deposit. The quote reference (parent_quote_id) is then absent. Factur-X type 386 compliance is maintained in both cases.

Is the Factur-X type 386 file accepted by Chorus Pro?

Yes. Scell generates a PDF/A-3b with embedded CII XML, compliant EN16931, FNFE schematron passed. Chorus Pro accepts this format for B2G transactions. For B2B via Peppol, the file also passes Peppol validators.

How are deposit invoices stored?

Each invoice is stored on Scaleway S3 with Object Lock COMPLIANCE (11-year preservation, technically impossible to delete). The SHA-256 hash is recorded in the ISCA ledger. Two independent proofs: S3 WORM + hash chain.

Can I have an IBAN on the deposit invoice?

Yes, via the iban field of the issuing Company (Factur-X tag BT-84). If filled, the wire transfer payment tag is included with IBAN + BIC (BT-86). If absent, the invoice uses payment code 42.

Are L441-10 legal notices automatically included?

For B2B invoices, late payment penalty notices (3× legal rate + €40 flat fee) are automatically generated in payment_terms. For B2C invoices (buyer_is_individual: true), these notices are omitted per regulations.

What is the difference between Factur-X, UBL and CII formats?

Factur-X is the Franco-German format (PDF/A-3b + XML CII). UBL is the European format used in the UK, Belgium, Netherlands. CII is the ISO standard of the XML embedded in Factur-X. Scell generates all three. For France, Factur-X is the DGFiP-recommended standard.

The problem

→Missing or malformed type 386 — consumer tools generate a standard PDF without the invoiceTypeCode 386 tag. Result: EN16931 non-compliance, FNFE validator rejection, VAT dispute.
→Incorrectly calculated due VAT — without CGI art. 289, deposit VAT is not declared at the right time. The rate is applied to the full amount instead of the deposit amount.
→No link to source quote — the deposit is not linked to its quote. Tax audit impossible, ISCA chain broken.

Our solution

→Automatic and validated type 386 — convertToDeposit or invoice_type: 'deposit' sets the 386 tag in CII XML, validated via FNFE schematron. Zero configuration.
→VAT calculated on deposit amount — percent or amount → immediate VAT CGI art. 289, calculated on deposit tranche only, deductible from balance BG-22.
→Automatic parent_quote_id — the quote link is written to the invoice and ISCA ledger. Full traceability, fiscal FAC-YYYY-NNNN sequence.
