Commissions for the friends you have referred through Chit Chats' referral program will be added to your account as credits. Commissions from eligible shipments up to and including the 15th of the month will be added to your account balance on the 1st of the following month.
You can check your expected commissions at any point from your account by going to Settings (bottom-left) > Refer Friends & Earn > Referral Earnings.
Here you can also see the commissions that have already been paid out as well as the amount pending for the next cycle.
