I run a webshop selling handmade candles. Recently, we created two candles for ourselves (think glass, soy wax and fragrance oil). We do this as testers, to test whether the candle actually burns with the material and oil content we want to use. It goes without saying that we can no longer use these glasses to sell afterwards. Do I create a sales invoice for myself? Is there an entry for this in the accounts? I would love to hear from you. Thanks in advance.
