The affiliate commission rate is 15%. The commission is counted for both Planyo PRO (subscription-based) and PRO-COMM (commission-based) accounts for the whole duration of a planyo site. There is no commission for sales of additional products such as SMS and FAX packs because we only resale these services. For example, if a client referred by you uses Planyo for a 5-year period, your referral fees get accumulated every month of this 5-year period.
