Billing Mode Field
Billing mode tells buyers how payment works.
Use one-time purchase when the buyer pays once for the listed version or included update window.
Use subscription when access depends on ongoing payment. Subscription products should use Lyrinox license keys so your software can check whether the buyer still has active access.
Be direct. If support, updates, hosted services, API access, or premium features depend on subscription status, say so in the listing.
