An Member can mark someone that owes them a payment by going to the graphical lineage report.
On the graphical lineage report Members who have not paid will appear red.
Click on the red icon and then on the next page you will see a link on the right side where it says how much the Members owes you.
You can click on that link and then manually enter the payment amount you've received.
After you have completed this and marked an Member in your downline as paid they will still show as red as if they hadn't paid.
Also, in the view Members report they will still show as suspended.
The next time they attempt to login it will see that they are marked as paid and will change their status from suspended to active.
Once logged into the members area the Member would go to the "Share
From there they would need to go to the graphical lineage report.
Depending on your settings, they may already be taken to that page when they click the "Share" button.
On the graphical lineage page inside the "Share" they would click on the icon for the Member they wish to mark as paid.
From there, on the right side they will see a link that says "Amount Owed to YOU:
" and specifies an amount.
Click on this link, and it will take them to a page where they can enter the payment amount received.
