Why it matters now: a non-compliant invoice can cost your B2B customers their VAT deduction — the pressure to send proper e-invoices comes from your own buyers.

Everything the mandate requires. Nothing you have to think about.

Install, enter your company details once, and every new order gets a compliant e-invoice — in the right format for your customer's country.

Sequential gap-free invoice numbers including a linked credit note

Gap-free numbering

Sequential, audit-proof invoice numbering with configurable prefixes — the way tax auditors expect it.

Archive with tamper-evident hash chain verified across all documents

Long-term archiving

Invoices stored in their original format on EU servers for the full statutory retention period (8–10 years), with tamper-evident hashes and one-click export.

Compliance checks for a 0% VAT invoice showing the correct legal exemption reason

Built for your accountant

Bulk ZIP and CSV exports for tax filing. VAT ID capture with VIES validation and a German & French interface are on the roadmap.

How it works

From install to your first compliant invoice in under five minutes.

Install & set up

Add InvoNorm from the Shopify App Store. Enter your company details and VAT number once — the setup wizard does the rest.

Automatic invoicing

Invoices are created automatically for your orders, with the right format and tax treatment per country. Fine-grained rules (B2B-only, on request) are on the roadmap.

Forget about it

Invoices are generated, delivered and archived automatically. You get a monthly summary and your accountant gets clean exports.

See it validated

Compliance isn't a claim — it's a test result. Every invoice is checked against the official validators, and nothing ships unless every check is green.

Invoice compliance checks all green: EN 16931 semantic model, embedded factur-x.xml, XMP Factur-X metadata and SHA-256 hash chain

✓KoSIT validator

The official validator behind Germany's e-invoicing standard. Every invoice is checked against the full EN 16931 and XRechnung rules — semantics, not just well-formed XML.

✓veraPDF

The authoritative PDF/A validator. Every hybrid invoice is verified as a genuine PDF/A-3 with the XML embedded exactly the way bookkeeping systems expect.

✓Green before every release

Both validators run in our release pipeline. A single red check blocks the release — that's the bar for software your tax filings depend on.

No accounting software required

The usual route to compliant e-invoices runs through an accounting-suite subscription. InvoNorm runs natively in Shopify — one app, done.

Frequently asked questions

Do I really need e-invoicing for my Shopify store?

If you sell to business customers in Germany, France, Belgium or Poland — increasingly yes, by law. Germany already requires every business to be able to receive structured e-invoices, with issuing becoming mandatory from 2027. France requires all businesses to issue e-invoices by September 2027. Penalties apply for non-compliance.

What formats does InvoNorm generate?

At launch: Factur-X (France), ZUGFeRD 2.x (Germany) and XRechnung (German public sector) — all based on the European standard EN 16931 and tested against the official KoSIT and veraPDF validators on every release. UBL and Peppol BIS 3.0 network delivery are on the roadmap shortly after launch.

Does it work for B2C orders too?

Yes — invoices are generated for every order, and consumer invoices are compliant PDFs where structured formats are not required. Per-order rules (B2B-only, on request) are on the roadmap.

Where is my data stored?

All invoice data is processed and archived exclusively on servers in the European Union, with tamper-evident hashing and GDPR-compliant processing. A data processing agreement (DPA) is available for every plan.

When can I install it?

InvoNorm launches on the Shopify App Store in September 2026. Join the waitlist and early-access stores get 6 months of the Growth plan free.
