Hello invision community!

I have a question, I would like to know how to add a balance system to the user panel, that is, have a payment system in the system, I want to do something like:

User refers 1 a new user and earns $1 on their panel.

Are there examples or systems to implement?

Thank you.

There is currently no referral system based on purely registration. The current referral system works that if a user refers someone who then makes a purchase, the individual who made the referral can earn a percentage of the purchase.
