Each tool does one back‑office job properly.
Small, focused apps for commerce compliance and bookkeeping. Nothing else bolted on.
Export für DATEV and EU Compliance Kit are Wix apps (with Shopify versions), one is a Shopify app, one is a web app for German and Austrian tax advisors, one is a free WooCommerce plugin, and E-Rechnung is an add-on for Google Sheets and Excel. Each has its own site, support address, privacy policy and terms.

Export für DATEV
Orders and refunds as a monthly DATEV posting batch (EXTF) for the merchant's German tax advisor. SKR03/SKR04, OSS, refunds, gift cards, and the quarterly OSS return as an upload file for the BZSt portal. Runs inside the Wix dashboard or the Shopify admin — one click per month, no file to move. In the Wix App Market · in the Shopify App Store · how it differs from Buchungsstapel.

EU Compliance Kit
Nine EU rules on the product page: Omnibus 30-day prior price, the withdrawal button, the EU legal guarantee notice, the price line, delivery time, battery and e-waste notices, GPSR safety details, the GARAN durability label and food information. Six are on the free plan on Wix. New since 27 September 2026, when the EU rules on environmental claims took effect: a check that reads product texts and flags wording such as “sustainable” or “climate neutral” that now needs proof or more precise wording, with suggested rewrites. Free on Wix. Also on Wix, in Pro: digital product passports with a QR code and a public passport page, ready for the EU battery passport from February 2027. In the Wix App Market.

Buchungsstapel
For German tax advisors: clients upload their shop's monthly order export (CSV) through a link, the DATEV posting batch (EXTF) arrives by mail with every gap flagged. Nothing stored. Kanzlei plan for many clients. Reads Shopify, WooCommerce, Wix, Shopware 6, Etsy, Kaufland and eBay (beta) exports, and books the marketplace fees of eBay, Etsy and Kaufland too. For Austrian advisors it writes the BMD NTCS posting import or the DATEV file RZL reads, on the Austrian chart with 20/10/13 % — free while in beta. The same posting batch as Export für DATEV, but from the file instead of the shop: no store access, any platform, any past month.
-
Buchungsstapel Order Export
WooCommerce has no order export in core. This free plugin adds one: pick a month under WooCommerce → DATEV-Export, download the CSV that Buchungsstapel turns into the posting batch. No settings, no database tables, nothing leaves the shop. What it exports, in German.
-
E-Rechnung
XRechnung and ZUGFeRD invoices from a spreadsheet, for the German e-invoicing mandate. Write invoices as rows; the add-on checks them against EN 16931 and XRechnung rules, points at the cell that is wrong, and creates the ZUGFeRD PDF or the XRechnung XML (CII or UBL). German tax cases from Kleinunternehmer to reverse charge, Leitweg-ID, GiroCode, a DATEV booking batch, and incoming e-invoices read back into the sheet. Invoice data stays in your Google account or your workbook. 30-day free trial. Plus a free XRechnung viewer that opens a received e-invoice in the browser without uploading it. In the Google Workspace Marketplace.
