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.

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.
