PDF Vault is a done-for-you digital business-in-a-box. Members license ready-to-sell PDFs that come with a hosted sales page, and they keep 100% of their sales. It earns money two ways: one-time license fees plus recurring monthly hosting. Tiered pricing raises the price as licenses sell, so each product earns more as it fills and early buyers move fast. Licenses are capped, and new products launch in weekly drops, so the doors open just once a week. That scarcity creates real urgency.
