At Magic Heidi, we've been developing a cross platform invoicing solution for Switzerland. Our aim is to enable all Swiss IT providers and make it as easy as possible for everyone to generate invoices.
We're opening up our API to allow anyone to generate valid Swiss invoices with QR codes. This document describes our API and provides some examples to help you get started.
For any queries, please feel free to email us at hello@magicheidi.ch.
