The Fab EULA clearly states that “code plugins […] are offered on a per seat basis”. However, the current storefront labels, Personal and Professional, do not communicate this requirement clearly to buyers during purchase.
Suggestion:
When a buyer selects a code plugin, you could display a tooltip or prompt that clearly indicates that a code plugin requires one license per user (seat), regardless of the license type. And if possible, they could specify the number of seats they intend to purchase.
