There are a few different ways to see how much you need to pay to your Licensors:
Outstanding Balances:
This report (Royalty ➜ Reports ➜ Outstanding Balances) shows any balances for Licensors who have had a statement generated. To do this, search for a Licensor and run the report. If the Minimum Payout threshold you set has been reached, the amount payable will display in the Payable column.
Licensor Invoice Listing:
This page (Royalty ➜ Licensor Invoices) will show any outstanding invoices you have received from your Licensors, with the Value column displaying the total amount they are requesting payment for.
Licensor Invoice Submission Page:
This page (Royalty ➜ Licensors ➜ search for a Licensor ➜ click the 'Submit Invoice Page' link on their Licensor Details page) will show the amount owed to a specific Licensor, in the same way that they will see it themselves when submitting an invoice. Additionally, the Licensor Details page will show you the amount owed to them, their Minimum Payout threshold, and their Invoice Submission Mode.
