NederlandsA DSFinV-K export is a standardised cash register data file required by German law. Properties using Mews as their electronic recording system must provide it on request during a tax audit or cash register inspection. Property administrators and accountants can download the export from the Fiskaly Dashboard, outside of Mews Operations. Having the export ready means you can respond to an audit quickly, with no manual data preparation needed.

What is a DSFinV-K export?
DSFinV-K, short for Digitale Schnittstelle der Finanzverwaltung für Kassensysteme, is Germany's mandatory cash register export format under KassenSichV. When a tax auditor requests an audit or cash register inspection, your property must provide a ZIP file that documents your cash register transactions, including product names, VAT breakdown, and payment methods.
Do I need to set anything up?
No. Mews activates DSFinV-K automatically for all German properties using Mews PMS as their cash register system, provided they have an active SIGN DE integration. There is no additional cost and you need no additional configuration. Mews automatically submits a daily Cash Point Closing to Fiskaly in the background, so when you receive an audit request, the export is ready to download.
What credentials do I need to access the Fiskaly Dashboard?
You need your existing Fiskaly credentials. Mews provided these when setting up your SIGN DE integration. If you have lost access, contact your Mews account manager.
How do I download my DSFinV-K export?
In the Fiskaly Dashboard, go to Germany > DSFinV-K > DSFinV-K Exports and click Trigger DSFinV-K Export. Select ZIP as the file format, as it works with the most common validation tools. TAR format is also available, but Mews does not recommend it.
Once you download the ZIP file, you can hand it to the auditor or your accountant.
What does the export contain?
The ZIP file contains human-readable CSV files documenting the following for the selected date range:
- Every cash register transaction
- Product names and quantities
- VAT breakdown by rate
- Payment method breakdown
- Master data: company name, address, VAT number, and cash register details
My organisation has multiple properties. Do I need to download separately for each one?
Yes. Each property has its own cash register data in Fiskaly. You need to download the export separately for each property you need to cover.
What if the export fails during an active audit?
Contact Mews Support immediately via the Mews Help Center. Mews treats export failures during an active audit as a priority issue.
What if I need data from before July 2026?
DSFinV-K exports cover data from 1 July 2026 onwards. If you are audited for a period before this date, contact your Mews account manager, who can arrange a backfill on a case-by-case basis.
With DSFinV-K set up automatically and your Fiskaly credentials in hand, you are ready to respond to any tax audit request quickly and confidently.
