Shopify TSE Help: KassenSichV Setup for German POS Stores

Shopify supports the app itself and setup takes a few screens. The work around it decides whether an audit goes smoothly.

Tax identifiers first. Setup asks for a VAT ID and a 13-digit Steuernummer. Have both ready before anyone opens the app, confirmed with your tax adviser.

Complete location addresses. TSE registration needs a full address for every store location, so gaps in Shopify's location settings get fixed before activation.

Every location selected. Shopify's setup asks you to include all retail locations, including ones that only handle refunds and exchanges.

Receipts that carry TSE data. Auditors check TSE data on printed receipts. Any receipt printer supported by the current Shopify POS works. A POS setup specialist handles hardware and the app update.

A DSFinV-K export you have tested. Pick a date range and a ZIP arrives by email with DSFinV-K data, TSE certificates and Shopify transaction data for current and past active locations.

The cash register declaration. You create a taxpayer profile in the app and export an XML declaration, which arrives by email within 24 hours. Your bookkeeper or VAT setup specialist should see it next.

Single-store shortcut. One German shop, a current POS app and tax numbers in hand: Shopify's own setup guide is enough.

Few Shopify specialists work on German cash register rules. Look for someone who knows Shopify POS well and works alongside your Steuerberater rather than replacing them. Shopify experts in Germany are a sensible place to start.

Ask what they need from you. A good answer lists the VAT ID, the 13-digit tax number, full addresses for every location, and which locations take payments, refunds or exchanges.

Ask how they test an export. They should run a DSFinV-K export for a short date range and confirm it holds TSE certificates and transaction data for every active location.

Ask about the declaration. Expect them to know the 2025 reporting duty and the XML export from the app's taxpayer profile.

Ask who gives tax advice. A Shopify specialist configures the app. What the law requires of your business is a question for a German tax adviser.

Distrust any guarantee that the tax office will accept your setup. Only the authorities decide that.

One location, one day, one export. Activate a single location, ring up a sale and a refund, print both receipts, then export that day and send it to your adviser.

Paid plans, priced per location. The app runs on all paid Shopify plans. Billing is $9 USD per store location per month from the install date, through the App Store, in addition to POS subscription fees.

The TSE lives in the cloud. In-store transactions are stored externally by Fiskaly, a third-party provider whose BSI-certified cloud TSE is the certified part of the setup.

Locations switch on and off. TSE activates per retail location and can be deactivated at any time. Exports still cover past active locations.

POS must be current. Shopify asks you to update the POS app to the latest version before setup.

The rule has applied since 2021. Shopify's help center states that German retail merchants must comply with KassenSichV from April 1, 2021.

Everything arrives by email. Transaction exports come as a ZIP, and declaration XML files can take up to 24 hours.

Two interface languages. The app is available in English and German.

Settings stay editable. Tax identifiers change under Settings, and active locations under Manage TSE.

German POS compliance work on Shopify usually comes in these pieces.
