Error in the "manage billable expense" app, "trying to use an account that has been deleted." All of the accounts in the unbilled expenses report are active. Help?

Let's work together to fix this error, @kvwood.

My priority is to make sure you're able to successfully get passed the error and ensure QuickBooks works as it was before.

You're prompted with the error when the system detects that the Expense account or Expense item you’re trying to manage were accidentally mark as inactive. To fix this, here's how:

1. Click the Accounting tab.
2. Select Chart of Accounts.
3. Look for the account where your billable expenses are mapped.
4. If you can't locate it, click the Gear Icon above the Action column.
5. Choose Include Inactive.  
6. Once more, locate the account associated with your payroll expenses.
7. If is mark as Deleted or Inactive, click the Make Active option. 

If the error persist, I'd recommend contacting our Customer Care Team. They have tools to look up your account on a secured environment and check the root cause of the error prompt.
