The Best Shopify Invoicing Apps Compared

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, and e-invoicing as ZUGFeRD — natively inside Shopify Admin. The import-ready DATEV booking batch (EXTF) and the configurable CSV export are currently in a closed beta. Other apps set other priorities: Sufio on international invoice design, Order Printer Pro on document printing, Billbee and lexoffice on processes outside the Shopify admin. Which one fits depends mostly on whether you want the bookkeeping inside the shop or in a system of its own — the table above sets the differences side by side.

GoBD (German principles for the proper keeping and retention of books) requires, among other things, unalterable audit-proof documents, gapless sequential numbering and the retention of the vouchers – for invoices eight years rather than ten since 2025 (§ 147 Abs. 1 Nr. 4 in conjunction with Abs. 3 AO). Not every Shopify app brings this along: apps that only offer document printing are no substitute for audit-proof archiving. Easy Invoices archives the documents created in the app audit-proof and, for as long as your subscription runs, for 10 years, with gap-free numbering and traceable corrections via cancellation invoices (Storno) and credit notes. Whether your bookkeeping as a whole is GoBD-compliant also depends on processes outside the app and is for you and your tax adviser to confirm.

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 optionally embeds a ZUGFeRD 2.x XML (EN 16931) into every invoice, credit note and cancellation and delivers the PDF as PDF/A-3 — an e-invoice format recognised by the German Ministry of Finance. XRechnung for public authorities is not produced. On top come GoBD-compliant archiving and the PDF archive for your accountant; the DATEV booking batch (EXTF) and CSV export are in a closed beta.

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.
