Shopify accounting & e-invoicing: the complete 2026 guide

June 18, 2026 · 8 min · zrapp.group

For Shopify merchants, accounting is more than "writing an invoice": it is about compliant documents, correct taxes across borders and a clean hand-off to your bookkeeping. This guide maps out every building block and links to the detailed how-tos.

Key takeaways

Shopify accounting has three building blocks: compliant documents, correct taxes and connecting to your accounting software.
B2B e-invoicing (ZUGFeRD/XRechnung) becomes mandatory in stages through 2028.
Taxes depend on the case: domestic, OSS (EU B2C), reverse-charge (EU B2B) or the §19 small-business rule.
With belegio (documents) and zrapp (accounting connection) the whole process can be automated.

Block 1: compliant documents

Shopify does not create § 14-compliant invoices, only order confirmations. You need real, GoBD-compliant documents, created automatically. Start here: create Shopify invoices automatically.

Plus other document types: delivery notes and credit notes and cancellations.

Block 2: e-invoicing (ZUGFeRD & XRechnung)

B2B e-invoicing becomes mandatory in stages through 2028. The timeline is covered in e-invoice mandate 2025–2028, the format difference in ZUGFeRD vs XRechnung, and the B2B workflow in receiving & sending e-invoices.

Block 3: getting taxes right

The tax case depends on the customer and country. EU consumers fall under the OSS scheme, EU B2B under reverse-charge, and small businesses under the §19 rule.

Block 4: connecting to your accounting

Paid orders should land in your accounting automatically, not by hand. Here is how to connect Shopify to sevdesk or Shopify to Lexware Office. The mechanics are in auto-posting orders, and tool selection in the accounting apps comparison.

Frequently asked questions

Do I need a separate accounting app for Shopify?

Yes. Shopify does not cover document creation, e-invoicing or the accounting connection. Apps like belegio (documents) and zrapp (connection to sevdesk/Lexware Office) close that gap.

What is the first step?

Automating compliant invoices. After that, enable e-invoicing and set up the accounting connection.

Does this also apply to AT and CH?

The core principles yes; tax rates and thresholds differ per country. The linked detailed guides cover the specifics.
