Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureFrom 2027 and 2028, invoices between businesses in Germany must be e-invoices, whether or not your customer has a VAT ID (§14(2) UStG). Faktora creates XRechnung and ZUGFeRD from every order, including gross prices, discounts and partial refunds; the format is tested with the official KOSIT validator. Refunds become credit notes, automatically if you like.
Invoice9 automatically generates EU-compliant invoices for every Shopify order. It detects the buyer's country, selects the correct format (ZUGFeRD for Germany, Factur-X for France, PEPPOL for Belgium and Netherlands), validates EU VAT numbers via VIES, and sends the invoice by email — with no manual steps.
