Hello, @Jbenedik.
Your referrals must stay subscribed for 60 days before becoming eligible for a cash referral reward.
To further check if you have successfully referred them using your link, I suggest reaching out to PartnerStack Support or use the Contact Us chatbot at the bottom of the Ambassador Hub. Their tools can check this in a safe and secure environment.
For more details about this, check the following link and scroll down to Where do I go for help part: https://quickbooks.intuit.com/ambassadors/.
Check the following article for more information about the QuickBooks Ambassador Program FAQ.
I'm always here if you have any other concerns. Keep safe and have a great rest of the day!
