Features
The done-for-you EN 16931 e-invoicing readiness service for US/UK SaaS companies and sellers whose German and EU business customers can no longer process a plain PDF — invoice-format audit, field-gap map, validated sample pack, rollout checklist. Documents and format only, never tax advice.
What NormInvoice does for you
EN 16931 field-gap audit of your current invoice template, scored report, prioritised fix list.
Everything in Audit + sample validated e-invoice pack (your data, both German formats) + rollout checklist + AP-handover note you can send German customers. (Most popular.)
Mandate-change digest (Germany + ViDA), quarterly re-audit of your live template, rejection-risk alerts when rules or buyer requirements change.
How it works
Send us one real invoice (redact amounts if you like — we check fields, not your revenue) and tell us which system issues it.
Within 3 business days you get the field-gap map: every EN 16931 business term scored PASS / WARN / FAIL against your template, with the exact fix for each gap.
Pack buyers also get a sample validated e-invoice pack — field-complete XRechnung-oriented and ZUGFeRD-oriented examples built from your own invoice data — plus the rollout checklist your dev/finance team follows to go live.
Questions
Is this tax advice?
No. NormInvoice is a documents-and-format service. We check field presence, format, and internal consistency against EN 16931. VAT rates, reverse-charge treatment, registration, and filings stay with your tax adviser.
What do you need from me?
One sample invoice, the name of your billing system, and whether you have a German establishment/VAT registration (so we flag which duties are direct vs. customer-driven).
What formats do you cover?
XRechnung and ZUGFeRD (≥2.0.1, mandate-ready profiles), Peppol BIS Billing 3.0 readiness signals.
