Connect Shopify to Lexware Office (lexoffice)

June 14, 2026 · 5 min · zrapp.group

Lexware Office, known until recently as lexoffice, is the accounting tool of choice for many Shopify merchants. Getting every order there automatically and tax-correct needs a reliable connection. This article shows how that works with zrapp.

Key takeaways
  • lexoffice was recently renamed Lexware Office. The principle and API connection stay the same.
  • zrapp creates an invoice in Lexware Office for every paid order automatically.
  • Taxes are determined correctly per order (domestic, EU B2B, OSS, § 19).
  • E-invoicing is supported, ready for the obligation through 2028.

Lexware Office instead of manual entry

Connecting your Shopify store to Lexware Office removes manual order entry. Revenue, taxes and customer data flow into your accounting automatically — the basis for a correct VAT return and a smooth export to your tax advisor.

The name changed (from lexoffice to Lexware Office), but the API connection and the principle stay the same.

What gets transferred automatically

zrapp syncs via webhook in real time:

  • Paid orders as invoices in Lexware Office
  • Refunds as credit notes
  • Customer data as contacts
  • Invoice status back as a metafield on the Shopify order

Correct taxes for every order

zrapp determines the right tax case automatically: domestic sales at the standard rate, intra-EU B2B with a valid VAT ID (reverse-charge), EU B2C via OSS at the local rate, and the § 19 small-business rule. For international orders this automation is crucial.

Using sevdesk instead? Then connect Shopify to sevdesk will help.

E-invoicing & 2028-ready

With the e-invoicing obligation being phased in through 2028, the structured invoice format becomes mandatory. zrapp supports e-invoices so your documents meet the upcoming requirements. For background, see create Shopify invoices automatically.

Set up in a few steps

Install zrapp from the Shopify App Store, connect your Lexware Office account via the API key and configure tax status and options. New orders are then transferred automatically; older ones can be pulled in via the historical import.
