Ok, lets start at the beginning. I purchased goods for office maintenance and grv'd it to my supplier using 4350/000. My boss has a house on premises and the goods was used for his house. I don't want it in my books but because I have to grv my supplier, I had to bring it in. Now it is lying on my trial ballance and I want it off. I made out a Return & debit to contra the purchase note. Then I made out an Invoice on my cash account which i want to clear with a general journal
1. CR Invoice
2. DT Cost of Sales
It won't allow me to CR an customer account on General Journal.
How do I fix it?
