New customer commission
Available from the Professional plan
New customer commission allows you to set up a different commission for affiliates when they bring a totally new customer that does not exist on your Shopify customer list.
This feature is separate from First commission from Lifetime commission function that First commission gives commission for customers that did exist on your store but it's the first time they were referred by affiliates. Besides, you can now set up New customer commission without having to enable Lifetime commission like before.
This feature helps encourage and motivate your affiliates to promote your store widely to refer new customers for a (could be) higher commission amount. It can also help incentivize underperformers to be more active in the affiliate campaign.
Consequently, new customers can offer many benefits for your business, including: increased sales, heightened brand awareness, increased customer base for feedbacks and data to improve your brand overall.
To enable New customer commission, go to Management > Programs > Create new program or locate the program you want > click Edit program (the blue button) > Advance > switch on New customer commission.

After that, kindly select commission type for this function, whether it could be Flat per order, Flat rate per item or Percent of sale then input an amount for it.
In the example above, New customer commission type is Percent of sale and amount is 30%. It determines that affiliates will receive 30% commission on total sales when they are able to refer brand new customers to your store.
