I have an online and a physical store based in Austria which means it needs to comply with the Registrierkassen-Sicherheitsverordnung (RKSV).
Does anyone know of a good and more affordable app that can handle RKSV compliance? So far, I’ve only found two options, and both cost around €15 per month, which feels quite expensive. Are there any cheaper or possibly free alternatives available?

Hi,

RKSV compliance is required for any physical store in Austria, so you’re definitely checking the right things.

There are options that can be cheaper than €15/month depending on what features you need. A few apps and providers offer lower-cost or “free to install” plans, but the final price often depends on whether you need a fiscal certificate, signed receipts, or DEP export. Some providers include these; others charge separately.

Most Austrian merchants using Shopify POS look at options like:

  • OpenFiskal (supports RKSV and often cheaper depending on usage)

  • POSModule / RKSV Fiscal App (built specifically for signing receipts and QR codes)

  • Fiskaly SIGN AT (a fiscalization service that some apps integrate with)

The key thing is checking whether the app covers the full RKSV workflow (signing, QR code, DEP export) and whether certificate fees are included.

If you don’t understand any part of this, I would love to explain it more clearly.

Hi,
Thank you the detailed message. I’ve looked at both OpenFiskal and the POSModule / RKSV Fiscal App, and they seem very similar. Could you explain what you meant by “checking whether the app covers the full RKSV workflow (signing, QR code, DEP export) and whether certificate fees are included”? I’m not sure I understand this at all. Could you also tell me whether both apps cover all of these or only some of them?
