You didn't show all of the image; if you are Job Tracking, that needs to be on the Items tab. You are supposed to set up and use Items. The Job reporting relies on Items. Items control the flow of data to the accounts, and can be two Sided, for expense and for income as that same thing you incur and charge to the customer. Inventory has three account links. If you are working with the Expenses tab, for COGS or a Balance Sheet account (such as Customer Prepayment or Tenant Security Deposit), that is why you have this issue = the Wrong Tab is being used for the data entry.

I have a handout for this, attached.
