Preparing accounting with Shopify has never been so easy....

Connect to Shopify with just a few clicks

With just a few clicks, you can connect your Shopify account to AccountOne. We'll take care of the rest for you together with your tax advisor. You can find out how easy the connection is in our helpdesk. We also provide your tax advisor with comprehensive support during onboarding.

Fully automated data retrieval

Our API interface retrieves data from Shopify several times a day and provides it as accounting data on a monthly basis.

Reconciliation with Payments

The revenue transactions are automatically assigned to the payments (provided the payment system is also connected to AccountOne). The fee items and payouts are also posted fully automatically.

100% DATEV compatible export

Our exports are fully batch processable. This means that no import profiles have to be created in the accounting department, but can be imported directly using the DATEV board tools.

Minimally invasive integration

AccountOne integrates into the existing API and tech stack without interfering with other systems.


Directly accessible via web browser without installation. 24/7 Up-to-Date!

The data is retrieved fully automatically via API. To connect Shopify, a private app with the corresponding authorizations must be created in Shopify. Simply follow our step-by-step instructions: Shopify Connection Guide

Each order from Shopify is individually evaluated in detail for VAT purposes. This is the only way to ensure that the 100%ig revenue postings arrive correctly in the accounting department. Revenues are booked by us using the individual booking procedure. In other words: Each order receives its own entry in the accounting.

In addition, we read the payments and fees from Shopify and also create postings for the tax consultancy. In this way, a payment transaction can be assigned to each individual revenue posting in accounting.

Shopify orders are posted using the single entry method - each order receives at least one entry line. If there are different tax circumstances, the posting may be split to reflect mixed tax rates.

AccountOne provides a DATEV-compatible CSV record for the orders from Shopify every month. This is regularly checked with the DATEV checking tools and guarantees a smooth import to DATEV. In addition, our export to DATEV is batch processable.

You therefore do not have to create an ASCII import, but can use the DATEV board tools to read in the data. This prevents errors during import.
