E-Invoice Auditor: every received invoice is checked
From 1 September 2026, your suppliers send you electronic invoices. The embedded XML must be valid, consistent with the readable PDF, and compliant with EN 16931. ERHA audits each invoice and delivers a clear control report.

Why e-invoices are a problem
An electronic invoice is not a PDF with an XML file stuck to it. The EN 16931 standard requires that structured content (XML UBL or CII) be consistent with the visual representation (PDF or readable invoice). Yet approved platforms only transmit: they do not check arithmetic consistency, detect duplicates, or flag malformed XML. Document verification is exactly the kind of repetitive task an AI can take over.
ERHA reads the embedded XML, recalculates totals and VAT, compares with the visual rendering, and detects duplicates by cross-referencing references and amounts. Every anomaly is flagged in a French report, with a link to the invoice concerned. The same compliance checking mechanics apply here, adapted to the Factur-X format.
What ERHA checks on every invoice
XML validity
The embedded XML file is parsed and validated against the Factur-X/UBL/CII schema.
Arithmetic consistency
Totals, subtotals and VAT amounts recalculated and compared line by line.
PDF ↔ XML cross-check
Amounts shown in the readable PDF are cross-checked against structured XML values.
Duplicate detection
Cross-reference of invoice numbers, dates and amounts to spot multiple submissions.
EN 16931 compliance
Verification of mandatory fields and European standard rules.
French report
A clear document, line by line, with anomalies flagged and justified.
How it works in practice
Five steps between receiving the invoice and the control report.
- 001
Receive
You forward invoices by email or drop them in your space.
- 002
XML read
ERHA extracts and validates the embedded XML against the appropriate schema.
- 003
Audit
Totals recalculated, PDF/XML compared, duplicates detected.
- 004
Check
Discrepancies and anomalies are re-checked and marked for validation.
- 005
Report
You receive a detailed control report in French, ready to archive.
Frequently asked questions
Which e-invoice formats are accepted?
Factur-X (PDF/A-3 with CII XML), UBL and CII. All formats compliant with European Directive 2014/55/EU are supported.
What happens if an invoice is not compliant?
Every anomaly is explicitly flagged in the report: invalid XML, VAT discrepancy, PDF/XML mismatch, or duplicate detected. You keep the trace and can send it back to the supplier.
Do I need technical skills?
No. You forward invoices by email or drop them in your space. ERHA runs the audit and returns a readable report. No XML or advanced accounting knowledge required.
