QB Issue Resolution:

When you have an expense, for the client or not, that is what it is, an expense

If you invoice the customer for that expense, then that is income to your business
On the P&L income is reduced by expenses

If you have QBO+, then in gear>settings>company settings>expenses>bills and expenses and turn on make expenses and items billable
check mark to track billable expenses and items as income
then in company settings>advanced>chart of accounts click the edit pencil and select the billable expense income account

Why intuit separated the two related settings is anyone’s guess

When you enter a vendor bill/CC charge/etc, you will see a Billable check mark box, check that and select the customer name in the customer block. The next time you invoice your customer, the system will ask if you would like to add the bill to the invoice.  IF you do not want to add the bill to the invoice, leave the billable check mark box blank, the cost of the expense will still count against the customer
