Any Penta customer who has an active account can participate in the referral program. 

In your Penta account within the menu section "Refer a business" is your personal recommendation code as well as an overview of your successfully completed referrals.

Important: The referral code is tied to your business. Every user of your account can share the referral code, however the reward will be applied to your business.

During promotion periods the reward amount might differ. If the referred business started their account creation during the promotion period, you are eligible to receive the reward from the promotion.

More information about Penta's referral program can be found here and in the Terms and Conditions.
