NineDigit eKasa vs OpenFiskal TSE & RKSV for POSfor Shopify (2026)
NineDigit eKasa and OpenFiskal TSE & RKSV for POS are both Shopify apps designed to address fiscal compliance for in-person sales, but they cater to vastly different markets and operate under distinct regulatory frameworks. NineDigit eKasa focuses specifically on Slovakian eKasa compliance, offering a solution certified by the Financial Administration of the Slovak Republic. Its core value proposition is to eliminate the need for an external point-of-sale system by integrating eKasa document issuance directly within Shopify. A key requirement is the integration with a protected data storage from Nine Digit, s.r.o., indicating a dependency on their proprietary hardware. OpenFiskal TSE & RKSV for POS, on the other hand, targets merchants in Germany, Austria, and Switzerland (DACH region) needing to comply with KassenSichV and RKSV regulations. It emphasizes secure transaction signing with QR codes printed on receipts, automatic Z-reports for simplified bookkeeping, and comprehensive support for audits. Its features, like FinanzOnline integration and DSFinV-K export, are specifically tailored to the DACH region's stringent accounting requirements. With significantly more positive reviews, OpenFiskal offers a proven solution, while NineDigit eKasa remains untested by user feedback at the time of evaluation.

Our Verdict
For a Shopify merchant operating in Slovakia and needing to comply with eKasa regulations, NineDigit eKasa is the specifically designed option, assuming the merchant is willing to integrate the required hardware from Nine Digit. The lack of user reviews represents a risk, but if compliant functionality is paramount, it's currently the only option directly advertised for that specific region.
However, for merchants selling in person within the DACH region, OpenFiskal TSE & RKSV for POS is the clear choice. Its high rating, positive reviews, comprehensive feature set covering TSE/RKSV compliance, and strong bookkeeping integration makes it a significantly more reliable and feature-rich solution.
Common Questions
Which app is easier to set up and use?
Based on the description, OpenFiskal likely offers a simpler setup as it integrates with existing Shopify-compatible printers. NineDigit eKasa requires specific hardware, potentially adding complexity to the installation process.
Which app offers better support for accounting and auditing?
OpenFiskal clearly offers better support for accounting and auditing, with features like automatic Z-reports, CSV cash book export, and specific exports for audits (TSE data, DSFinV-K, and DEP7). NineDigit eKasa lacks these features as it prioritizes simple eKasa order registration.
Which app is more cost-effective?
Cost-effectiveness depends on pricing, which isn't provided. However, consider that NineDigit eKasa requires purchasing a separate protected data storage, adding to the overall cost.
What happens if I move my business from Slovakia to Germany? Can I keep using NineDigit eKasa?
No. NineDigit eKasa is designed specifically for Slovakian eKasa compliance. You would need to switch to a solution like OpenFiskal TSE & RKSV for POS that supports German regulations.
Does either app integrate with other accounting software?
