XRechnung and ZUGFeRD e-invoices for Shopify

If you sell in Germany or to European businesses with Shopify, your customers are starting to ask for e-invoices. Since 1 January 2025 German businesses must be able to receive B2B e-invoices, and issuing them becomes mandatory in stages in 2027 and 2028. This app creates the e-invoice for every order on its own, with no separate invoicing software. If your company is in Poland, it also sends it to KSeF in FA(3).

What the app does

• ZUGFeRD 2.3 / Factur-X 1.07 PDF (PDF/A-3 with the XML inside) and XRechnung 3.0 (UBL), following the European standard EN 16931.
• Automatic invoice when the order is paid or when it ships, as you prefer, or by hand from the app.
• Automatic credit notes (Gutschrift) on full or partial refunds, linked to the original invoice.
• Sequential numbering with no gaps, with your own pattern (prefix, year, digits).
• VAT ID, company and Leitweg-ID at cart for B2B customers and public bodies. If you already use our VIES app, the VAT ID it validates is reused.
• Reverse charge on sales to businesses in another EU country, and Kleinunternehmer mode (§ 19 UStG).
• Invoice link on the order, ready for your notifications, and a ZIP export of any period for your accountant.
• Invoices in German, English, French, Spanish, Italian, Dutch or Polish.

Poland: KSeF (FA(3))

If your company is based in Poland, the app sends every invoice to KSeF (Krajowy System e-Faktur), the national e-invoicing system, in the FA(3) schema with your KSeF token. From 1 January 2027 KSeF is mandatory for all Polish businesses.

• KSeF number and verification QR code on every invoice PDF, and the UPO (official receipt) stored.
• Corrective invoice (KOR) sent to KSeF on every refund, linked to the original invoice.
• Buyer’s NIP in the cart and gap-free numbering.
• Sales in other currencies at the NBP exchange rate.
• KSeF TEST environment to try it before sending real invoices.
• Invoices and admin in Polish. KSeF is included in the same plans.

Important

Files are checked with the public XRechnung (KoSIT) and ZUGFeRD (Mustang) validators. The app creates the invoices and only sends them to an authority in one case: to KSeF, if your company is in Poland and you turn it on. It does not send them to Peppol. VAT rates are yours to set in Shopify: we do not give tax advice.

Data in the EU and 24/7 support

The app is hosted in the European Union (GDPR). Our support is excellent, immediate and always available, 24/7, in German too: appsupport@lineagrafica.es.

Plans and pricing

• Free: up to 50 invoices a month, everything included.
• Unlimited: $9.99 a month. Unlimited invoices, 7-day trial. Credit notes never count.

Going over the limit loses nothing: orders wait and are issued when you change plan or the month starts. Plans are billed by Shopify in US dollars on your Shopify invoice.

FAQ

Do I need invoicing software?

No. The app numbers and creates the invoices with your company details and each order's data.

What is the difference between ZUGFeRD and XRechnung?

ZUGFeRD (Factur-X in France) is a readable PDF with the XML inside; XRechnung is XML only and is what German public bodies ask for. The app creates both for every order.
