@danmo, I've been using your python plugin, thanks so much for making it. I have been having an issue though with nested lists within dictionaries and was hoping you could help.
My aim is to create an invoice from a service. I tried using the method createFromServices, but I always get an error saying that there is not a description for the service. I also tried creating the invoice separately and then adding the service to the invoice but with the same effect. When I create the invoice and add line items to it, including the service, it does not give me any errors, but none of the line items are added. Have you had any success linking services to invoices with your library?
