If Lifetime commission is enabled, whenever a customer makes a purchase referred by an affiliate, that customer would be automatically connected to the affiliate so the affiliate will get a lifetime commission for further purchases from the same customer.
To enable Lifetime Commission for a program, go to Management > Programs > locate the program you want > click Edit program > Advance > switch on Lifetime commission.
Once you have enabled Lifetime commission, you would have the option to Disconnect Lifetime commission after a certain period. It means that in case an affiliate and a customer are connected to each other by Lifetime commission after the first order, they will be automatically disconnected after a certain number of days, i.e. 100 days, if you set it up. Kindly note that this field is optional. If you leave it blank, the connection will remain lifetime until you manually disconnect them.
Aside from that, you can also set the First-time commission for the affiliate on the first order of any new customers referred by that affiliate.
By enabling the First commission option, your affiliate will get a different commission rule for the first commission while all future commissions will follow the program commission rate.
For example, if your Program commission is 10% and you set the First commission to be 20%.
If customer X buys from Affiliate A the first time, affiliate A will get a 20% commission for that order, but for all other following orders bought by customer X, Affiliate A will only get a 10% commission.
