Expense entries will be marked as billable if both the project and the expense type logged are billable.

You can  adjust whether or not an expense type is tracked as billable from the expense type’s details page.

1. Go to the Expenses page in your Time IQ account
2. Click the expense type you want to set as billable
3. In the right sidebar, toggle the “Billable?” option to “YES”
4. All future entries that use this expense type will now be marked as billable. (Requires that the project logged to is billable as well)
