OpenFiskal TSE & RKSV for POS vs WhatsApp Chat Button by AZDigifor Shopify (2026)
OpenFiskal TSE & RKSV for POS and WhatsApp Chat Button by AZDigi are both highly rated Shopify apps (5/5), but cater to drastically different merchant needs. OpenFiskal focuses on regulatory compliance for Point of Sale (POS) systems in Germany, Austria, and Switzerland (DACH region), specifically addressing KassenSichV and RKSV regulations. It automates fiscalization, ensuring secure receipt signing with QR codes, generating compliant Z-reports, and facilitating bookkeeping with CSV exports. Its target audience is Shopify POS merchants operating in the DACH region requiring compliance with fiscal regulations. WhatsApp Chat Button by AZDigi, on the other hand, is focused on improving customer communication and engagement. While its description is unavailable, its name suggests it adds a WhatsApp chat button to the storefront, likely enabling customers to easily contact the merchant. This app appears to be useful for any Shopify merchant looking to improve customer service and sales through direct WhatsApp communication. The vastly different functionalities and target audiences make these apps hardly comparable in a direct sense, despite both sharing the 'Selling in person' category.

Our Verdict
For Shopify merchants operating a Point of Sale system in Germany, Austria, or Switzerland and needing to comply with KassenSichV and RKSV regulations, OpenFiskal TSE & RKSV for POS is the clear choice. It's specifically designed to automate fiscalization and ensure compliance, offering features like secure receipt signing, automated Z-reports, and bookkeeping exports.
However, if the merchant's primary goal is to improve customer communication and engagement through direct WhatsApp messaging, and they don't require fiscal compliance features for the DACH region, then WhatsApp Chat Button by AZDigi is the more suitable option. Although the AZDigi app only has one review, the functionality is targeted at a very different need than OpenFiskal.
