Case Studies

Our own apps in action.

We don’t just talk about Shopify apps — we run them ourselves. These products are live in the App Store.

belegio

belegio.app

Invoices, delivery notes & credit notes — fully automated from Shopify, tax-compliant. Hosted in Frankfurt.

Challenge

Merchants create documents by hand — slow, error-prone and quickly overwhelming with e-invoicing, §19 or OSS.

Solution

Belegio creates documents automatically on payment — incl. e-invoices (ZUGFeRD & XRechnung, EN 16931) — and sends them to the customer. Made in Germany.

Digital Product Passport

zrapp.group/digitaler-produktpass

Digital product passports from Shopify — with the fields of the Battery Regulation, a QR code on the product and a public passport page.

Challenge

From 18 Feb 2027 every LMT, industrial and EV battery needs a product passport. Direct importers carry that duty themselves — and no shop system has the fields for it.

Solution

The app creates passports per model, batch or item, cites the legal source at every mandatory field, freezes published versions with a checksum and attaches QR code and link to the Shopify product.

zrapp

zrapp.de

Connects Shopify with sevdesk & Lexware Office — invoices, taxes and customer data automatically.

Challenge

Transferring order data to accounting by hand costs hours — with risk around tax rates and compliance.

Solution

zrapp transfers orders automatically via webhook, with smart tax automation (OSS, reverse-charge, §19) and e-invoicing — 2028-ready.
