If your plan manager asks you for the participant to be the recipient of the invoice and not them, that is not a problem. In Astalty, changing the recipient of an invoice is as easy fix.
To start this process you will need to do the following;
Navigate to the Settings menu from the main menu
Once here navigate to the Invoices menu item
Once in here you can see a similar screen to the screen shot below. Within the invoice Settings table click the "edit" button
After clicking the edit button a menu similar to the one below will show. You will need to navigate to the 'More' selection outlined by the orange box below.
After clicking the 'More' selection you will now see additional invoice settings. From within this setting you will be able to see that you can select either the Plan Manager, or the Participant to be the recipient of the invoice. This is outlined by the box below.
The images below outline the difference within the invoices from selecting either;
The recipient as the Plan Manager
The recipient as the Participant
