Hi i was looking for a payment tool like invoice ninja, but my customers would expect me to deliver official bills accepted by the bank.
I tried the demo but was not able to evaluate one question, pls help me understand its possibilities.
Here is a link to a freeware that makes such approved bills,
- One way is to use the api from that project, i spoke to the guy andreas he seems to do the project on his own.
I did make some python script to run selenium where i am able to use that api from qr-rechnung.net. if its of any use i could make it available.
- I can provide you with the official documentation, from six payment about layout, datastructure and its validity checks needed.
