[cannolamxcookie]

I have a shop located in Vienna austria.

i use in my shop a POS software called Roqqio.

ill be happy to work with shopify POS if that is an option. those Shopify POS is allowed by the austrian tax authorities? (finanzamt)

if not i wanted to ask if shopify can interface Roqqio software?

Thank you for your answer.
Warm regards Nimrod
