Creating an invoice

In principle, the tax authorities must be able to look at your invoice and see what is behind it. That is the worst-case scenario, of course, should you ever have a tax audit :)

In concrete terms, this means that the tax authorities must be able to see the full amounts that you would normally charge. So the commission must be clear, as must the product costs.

If you want to put all of that on one invoice, that's fine. But ideally, you should work with the total amount you would normally have (for commission and product costs) and put that on your sales invoice. Then add the commission and product costs as negative amounts to that sales invoice.

You can also do it completely correctly with three documents:

1. Simply enter product costs as expenses (you must then attach purchase invoices or receipts).

2. Invoice to the customer with the total amount (how you divide this up depends on what the customer expects).</Record commission as an expense (the person you are working with must then provide you with a commission invoice or commission note if they are a private person).

This way, your accounting will also be correct. To make it easy for the person you are working with, if they are a private person, you can also draw up the commission note yourself and question them to sign and have them send it back.

Thanks in advance, she will indeed create a commission invoice to which I pay her the 30% at the end of the month. I will enter that invoice here as an expense.

Thanks in advance for the clarification.
