On my web-shops, for now I have been using a classic affiliate program, what also works great. Invite Referrals will not replace this, but be an addition. However, to have happy customers referring friends in a simple way, is the best possible type of referrals that you can get. This is a type of referrals you will typically not get thought a classic affiliate set up, because most people will not join an affiliate program just to refer 1-5 friends.

I was so happy to see something like InviteRefferrals to come to AppSumo, as this is a type of tool that I have been looking for for a long time.

To be completely honest, I have only just implemented on a first website, but my first impression is really good and from watching several YouTube tutorials I am pretty sure this is a perfect match for me.

If you have a type site where it makes sense to have users to refer other users, then I would suggest that you test out InviteRefferrals or a similar tool, as this can bring huge added value.
