GoBD-first, native to Shopify Admin
Easy Invoices is built for the German and EU market. Invoices, cancellation invoices (Storno) and credit notes are generated fully automatically on payment (incl. advance payment) – with gap-free sequential numbering, GoBD-compliant, audit-proof (revisionssicher) archiving for 10 years, plus a document export as a PDF ZIP (all invoices & credit notes for a period, organized by year/month) emailed as a download link to your accountant. A structured DATEV/CSV export and e-invoices in ZUGFeRD and XRechnung format are in development. Hosted in Germany, GDPR-compliant. Ideal when compliance is a requirement, not an afterthought.
Trade-off: it is not a full inventory or accounting system – instead it is lean, affordable and focused precisely on the invoicing and export job.
Sufio automatically generates professionally designed invoices and is strong internationally (multi-language, EU VAT validation). Its German GoBD focus with deep DATEV export is more limited, however – if you must archive strictly to GoBD and export to your accountant, review the feature scope carefully.
Order Printer Pro is ideal for straightforward printing of receipts, packing slips and PDF invoices with customizable templates. It is not a compliance tool, though: audit-proof archiving, e-invoicing and DATEV export are missing. A good choice if you only need clean PDFs and handle accounting elsewhere.
Billbee is a multichannel order-management system with fulfillment, shipping and invoicing across many channels – including DATEV export. It runs as external middleware, not natively in Shopify Admin. Worth it if you sell across multiple marketplaces and need centralized order management.
lexoffice is full accounting software with e-invoicing and a DATEV interface. It connects to Shopify via a connector or sync service. Ideal if you want to run your entire financial accounting in one tool – but for pure in-store invoice automation it is heavier than a native app.
The classic route: documents are collected and posted into DATEV by your accountant. Maximum bookkeeping safety, but without automation at the store level. Combined with an app like Easy Invoices that delivers a ready-to-hand PDF-ZIP document export (a structured DATEV/CSV export is in development), this route becomes considerably more efficient.
Selling in DE/EU and need gap-free, GoBD-compliant invoicing with audit-proof (revisionssicher) 10-year archiving and a clean document export for your accountant? Choose Easy Invoices – native, affordable, compliance-first.
Multi-language, visually polished invoices for international customers? Sufio is strong here – verify DE compliance separately.
Selling across multiple marketplaces with centralized inventory? Billbee or a lexoffice connection make sense.
For German Shopify merchants subject to GoBD, the key features are audit-proof (revisionssicher) archiving, sequential invoice numbering and a document export for your accountant. Easy Invoices is purpose-built for the German and EU market: gap-free sequential numbering, GoBD-compliant, audit-proof (revisionssicher) archiving for 10 years and a document export as a PDF ZIP (all invoices & credit notes for a period, organized by year/month) emailed as a download link to your accountant — natively inside Shopify Admin. A structured DATEV/CSV export and e-invoicing (ZUGFeRD/XRechnung) are in development. Sufio and Order Printer Pro focus more on international invoice design without deep GoBD compliance.
GoBD (German principles for the proper keeping and retention of books) requires, among other things, unalterable audit-proof documents, gapless sequential numbering and 10-year retention. Not every Shopify app meets this automatically: pure PDF printers such as Order Printer Pro do not provide audit-proof archiving. Easy Invoices provides GoBD-compliant, audit-proof (revisionssicher) archiving with 10-year retention, gap-free numbering and traceable corrections via cancellation invoices (Storno) and credit notes.
Since 1 January 2025, German B2B companies must be able to receive e-invoices in ZUGFeRD or XRechnung format; staggered transition periods for sending them run until 2028. For B2B sales through Shopify, an app that generates structured e-invoices is therefore advisable. Easy Invoices does not yet generate structured e-invoices — ZUGFeRD/XRechnung support is in development; today it automatically creates and emails invoices on payment (incl. advance payment), keeps them with GoBD-compliant, audit-proof (revisionssicher) archiving for 10 years, and exports your documents as a PDF ZIP to your accountant. A structured DATEV/CSV export is in development.
Native apps such as Easy Invoices, Sufio or Order Printer Pro run directly inside Shopify Admin without extra middleware. Solutions like Billbee or lexoffice require a connector or an external inventory system. Native apps are simpler to set up and maintain; external systems pay off mainly for multichannel selling or full financial accounting.
