In my e-commerce I work in 2 different ways:
I buy the items from the producers and then sell them at a higher price, therefore I invoice the whole purchase and sales. This is easy to account on ERP, I create the purchase order then the sales order and from them, I make the invoice.
I don’t buy the items, I just make the connection between the buyer and the seller, then the seller sends the sales invoice directly to the buyer. In this case, I get a 4% commission from the seller. Therefore, I need to create an invoice for 4% of the total sold amount. How can I do this on ERP? Should I register the whole amount and then invoice the whole amount but specify that the amount to pay is just 4%? Or should I create a sales order directly for the 4% commission?
Thank you very much for your help.
