Hi Michelle29
The setup for the Item is wrong - you have the Sales account listed as the COGS account - so MYOB is posting both Sale amount and the COGS to the same account. The Income Account for tracking sales should be a 4-xxxx account.
When it works correctly (and AR2022 often doesn't when it come to Inventory) - when you Purchase an Item the cost gets added to the Asset Account for Inventory. When you Sell an Item it posts the sale value to Sales (4.xxxx) and the COGS to the Cost Of Sales Account from the Asset Account. This reduces the balance of the Asset account as the item is sold.
I suggest you review the transaction from the Transaction Journal - that will show you exactly where and what was posted. Your Sales Income will be 'understated'.
