When trying to create a new invoice in Time Tracker, you may sometimes see "There are no invoiceable items." error. There are no invoiceable items error in Time Tracker when adding invoice
This error means that for a selected client there are no items in a selected time interval for the new invoice. To fix this problem:
Make sure that the Clients plugin is enabled. You can do it on the Plugins page.
Make sure that at least one client is defined on the Clients page.
Create at least one new billable time record and associate it with the client.
Then, add an invoice. For this to work, new, not already invoiced, billable items must exist for the selected client between invoice start date and end date.
