Yes, as an Agency Manager, you can now add flat fees to your Legacy Agencies and invite new agencies at flat fees!
Simply do so by going to your "Agencies" tab and then find "Edit Fees" in the action menu as shown below.
From here select the fee type "Flat fee" at which point you will be asked to provide the currency the agency should be paid out in and how much you want to pay under "You Pay" and you will be able to see how much the agency will receive under "Agency Fee". For more information on the differences between what "You Pay" and the "Agency Fee" please refer to the processing fees FAQ article.
Additionally, you can also invite new agencies with Flat fees to join RecruitiFi from the "Invite Agency" page.
