The problem

Factur-X = 400 pages of spec. One missing field = Peppol rejection.

Each transaction type (deposit type 386, balance type 380, credit note, delivery BG-13) has its own mandatory fields. No mainstream invoicing SaaS produces valid Factur-X via API.

EN16931 spec

400 pages of BT-* and BG-* fields. One mistake invalidates the document.

2026 reform

Non-negotiable deadline for all French B2B issuers.

Strict Peppol

Schematron FNFE/CEN blocks any non-compliant file. Zero margin for error.

Features

One API call, one PDF/A-3b with EN16931-compliant CII XML.

BT-84 (IBAN), BG-22 (deposit deductions), type 386/380 fields are calculated automatically. The ISCA SHA-256 ledger records each document in a hash chain, anchored on Bitcoin.

How it works

Production in 1 day. 3 steps.

Unlimited sandbox, no credit card. Switch to production by simply changing the API key prefix.

Sign up + sandbox key

Account in 2 minutes. sk_test_* key immediately active. No manual validation.

First invoice locally

PHP/TypeScript SDK + builder pattern. You provide the buyer and lines, the API generates Factur-X.

Switch to production

Replace sk_test_* with sk_live_*. ISCA ledger starts. Your invoices become legally binding.

“We had 2 weeks to switch to Factur-X. The PHP SDK generated a compliant file on the very first call.”
