QB Issue Resolution:

Consulting and services do not use COGS which is related to the cost of a product that was sold.  your costs should post to an expense account you name Cost of Sales (COS), you can create a new account with that name use a cogs type account, that will put it where it should be on the P&L

QB works on items, so the item you sell for consulting should have the consulting income account selected on that item screen.  Same for each type of thing you sell, that item points/links to the income account you want it to post to.

Same concept for expense, one item posts to one account
