GSTFLY vs OpenFiskal TSE & RKSV for POSfor Shopify (2026)

GSTFLY and OpenFiskal TSE & RKSV for POS are both Shopify apps in the 'Taxes' category, but they cater to drastically different needs and markets. OpenFiskal focuses specifically on providing fiscalization compliance for Shopify POS merchants in Germany, Austria, and Switzerland (DACH region). It offers features directly related to meeting KassenSichV and RKSV regulations, like secure receipt signing with QR codes, automatic Z-reports, and cash book management. GSTFLY, on the other hand, has no user reviews or ratings and lacks any descriptive information to define its functionalities or target market. Given the complete absence of information and social proof for GSTFLY, it is impossible to ascertain its value proposition. OpenFiskal, supported by a perfect rating and 37 reviews, is clearly positioned as a solution for merchants in the DACH region needing to adhere to stringent fiscal regulations. It streamlines accounting processes through features like CSV exports for bookkeeping and dedicated exports for audits (TSE data, DSFinV-K, and DEP7), alongside direct integration with FinanzOnline for Austrian RKSV compliance. Its integration into the Shopify POS system is a key selling point.
