No, not right now. You can only reward a customer when their friend successfully places an order on your store.
If you are interested in rewarding a customer for something other than making an order, like:
- Making a referral only
- Getting a friend to sign up for a My Account
- Leaving a review
- Sharing on Facebook
- Sharing on Twitter
Chat with us and let's let us know you're interested in his functionality and we can prioritize it on our roadmap. Feedback like yours will help us decide what to work on next!
