Creating invoice

Hello Andras,

It's indeed a good idea to extend the examples with a full invoice creation flow to make API usage easier. I'll add this to the list of future tasks. Since this is code generated from OpenAPI, the Billingo documentation can also serve as a guide, available here, along with the repo docs that fully rely on it:
https://app.swaggerhub.com/apis/Billingo/Billingo/3.0.14

One important thing to note is that Billingo returns its own ID after submitting the client's billing data, so it's up to you to store that locally to avoid duplicates. If you don't have one yet, you can also request a test account from Billingo.

The other approach is bulk invoice import from Excel, which is already supported by Billingo. You can download the sample file from Billingo > Invoices and Documents > Bulk Invoice Generator. This method works well if you can generate the necessary data from an ETL tool like Pentaho Spoon.
