P&L , sales is showing both bills and invoices
My P&L report shows bills and invoices in sales portion which distorts sales . I can't see anything wrong in filters just as standard P&L report no customization...
I assume you're not entering an income account - your "Sales" account - on your bills directly, or you'd know why they're showing up on the P&L using the account.
Bills will use income accounts in cases where you use items / are purchasing items that have only one account, an income account.
To avoid this, edit the items you're purchasing on your bills and enable the purchase option. It'll have a different title depending on the type of item, and your QB version, but it'll always appear in the location seen here:
When you check the box, then you'll see options for values to use when you purchase the item:
When you add the Expense account and then save the item, you'll get a prompt like this:
Answer Yes, and then all of your purchases that you don't want to use your sales account will be updated to use the new purchase/expense account.
