Keeping it simple

Hello, I am trying to tailor my quickbooks to suit my needs now. My dearly departed Sister set my quickbooks up for my art gallery that had many artists all given a commission on sales. She was brilliant and it works wonderful for me at the time. Now I sell only the art that I make so it should be simple except it is not and I am not brilliant like my sister.

I need my quickbooks to allow me to receive products that I make and the cost is O because I have expenced on cost of goods and do not want to get paid until my books balance with sales. So am I the vender?? I need to create a bill? and then I sell the product..Oh boy..I can use all the help I can get!
