Of course it contradicts: "but it contradicts what is in the attachment"

Because, as I explained, Job Tracking and reporting means you were supposed to be entering Items on the Items tab. Not that Expenses tab. Example:

I run a Remodeling contractor business. Our payment for Garbage pickup includes the Shop Expense on the Expenses tab, which is Never job tracked. On the Items tab, I list the Garbage Service item for each Dumpster on site at each location where we are working. Some are Billable and some are not, depending on the contract with that customer for their project. The Check = the Total I am paying, and the Tabs = my Allocations.

And Items allow you to use Quantity, to set cost and price for the same thing.

If you run your Job Profitability Detail report, everything you entered is under the bottom line = No Item. Please see my attachment to see how this is Different, when you use the Job Tracking tools and functions by using Items properly.

And I also explained this: If you are posting to certain Accounts directly using the Expenses tab, the Billable status is Not Functional for all account types. An example is COGS and Balance Sheet accounts, because you are supposed to be using Items for this.

Please see my attachment; there is One Error on it as No Item = the Building Permit. Now run one of yours.
