Hey, I also sell my products in shops. At the end of the month, two shops issue me an invoice with a negative total. “For example: €150 worth of goods were sold in the shop in June. At the end of the month, the shop sends me an invoice with a negative total. Do they then transfer that 150 euros to my account?” So I don’t create an invoice for them. How do I correctly enter this in my accounts, as income?
