I am a self-employed midwife and am paid by the health insurance funds. However, this is always at the beginning of the next month and always for all patients combined. As this happens more or less automatically via the programme I work with, I don’t have to create a physical invoice. In this programme, I can consult an Excel file that states how much each health insurance fund has to pay me that month. According to the creators of the programme, this should be sufficient. Now I was wondering whether I should fill in this information under sales invoices or daily receipts.
