I'm here to help you sort this out, anesbit.
One possible reason the amount shows negative in the invoice could be it wasn't properly linked to the expense. Let's run the Transaction List by Customer report to check if there are billable expenses associated with the customer.
Here's how:
- Go to the Reports menu.
- Type in Transaction List by Customer in the search bar, then click to open.
- Click Customize.
- Under the Report period, enter the correct date the transaction was made.
- Click on Filter, then select Billable Expense Charge under Transaction Type.
- Once done, click on Report.
If the transactions are not correctly linked, we can delete them and recreate a new one. I suggest checking this article to record the billable expenses: Enter Billable Expenses.
Additionally, I've added an article that'll help you remove a billable expense charge easily. This ensures your QuickBooks record is accurate: Remove a Billable Expense Charge.
I'll be around if you need help in managing your billable expense. Have a great day!
