For most projects, payment isn't invoiced until after the work has been reviewed and accepted by a reviewer. Once the work is reviewed, it should be added to the current pay period's invoice.
As a reminder, pay periods run from the 1st -15th (paid on the 21st) and the 16th - end of the month (paid on the 6th of the following month).
Note: Work might not always be invoiced in the same pay period that you submitted it.
If you believe that your work has been approved and is still not showing in your invoice, please fill out a support ticket and we'll investigate.
