Pay, then receive secure intake instructions
No public invoice-upload form. After verified payment, we arrange a controlled intake for a representative, minimised corpus and optional mapping file.
Find recurring UBL, CII & Factur-X failures in production.
Validate a representative UBL/CII/Factur-X corpus during go-live and production remediation; surface recurring source-system failures and mapping gaps, record explicit human review decisions, and receive a traceable evidence pack without replacing your ERP or Plateforme Agréée. For SMEs and micro-enterprises without a live 2026 receive/production issue, the issuance/e-reporting obligation begins on 1 September 2027, so readiness planning is the relevant job rather than buying a production-remediation review now.
Built for finance, ERP and application teams with a live France e-invoicing production, migration, structured-output, rejection or re-test problem. This is source-system evidence and remediation support, not another one-file upload validator.
Free demo: no email, account or invoice upload. Paid service: Stripe-hosted checkout · controlled intake after payment · tax applied where applicable.
Current France phase
Production is live from 1 September 2026
The buying problem is now production validation, rejection analysis and remediation evidence — not pre-cutover readiness.
Pinned technical reference
DGFiP external specification v3.2
Rule and runtime provenance stays explicit so a future standards update cannot silently rewrite an old result.
Why this exists
A free validator answers “does this file fail?” We answer “what keeps failing across the source system?”
Single-file validators are useful and should stay free where possible. InvoiceBatch FR is for the next problem: repeated failures, mapping gaps, release drift and re-test evidence across a representative batch.
The same EN16931 or France-rule failure repeating across a source-system corpus
UBL, CII or Factur-X profile drift between exports, releases or business units
Source-to-business-term mapping gaps that create repeatable downstream rejection risk
Duplicate or conflicting invoice identifiers and corpus-level consistency problems
A failed production or migration re-test where you need evidence of what actually changed
Delivery path
Pay → controlled intake → pinned validation → human review → evidence → bounded re-test.
02
Run the pinned local standards preflight
The corpus is checked through the release-pinned factur-x/Saxon/CodeDB stack, France readiness rules and corpus/mapping analysis. Missing validation layers fail closed.
03
Review findings and receive evidence
Review-only findings require explicit operator decisions. Deterministic blockers cannot be waived into a clear result. The evidence pack records hashes, findings, coverage, review state and source provenance without embedding source invoice bodies.
Proof before purchase
Use the no-signup demo and inspect synthetic evidence before sharing a corpus. The example is illustrative, not customer proof.
Multi-source production problem
Up to three source systems and 300 representative invoices.
Up to three source systems and 300 representative invoices total, consolidated comparison and two bounded re-tests.
Delivery target. €1,500 multi-source: target first evidence handoff within 3 UK business days after complete intake. These are target windows, not a guaranteed SLA. We confirm the dated handoff in writing before substantive review starts; incomplete or unsupported intake pauses the clock.

Claim boundary
`PREFLIGHT_CLEAR` is a bounded technical result for the tested corpus, pinned runtime/rule snapshot and resolved review items. It is not certification, legal/tax advice, transmission proof, filing proof or an acceptance guarantee.
