Locate your Network Partner in your Client Management Tools as standard. Locate the "Payout" box within their client profile found at the bottom right of the page as shown below:
You can modify this data at any time, however, it will only reflect for future completed jobs and not any jobs already completed, even if payment/invoice is pending generation.
