Keep selling when products run out or before they launch, with preorders and back-in-stock alerts. When products sell out or haven't launched yet, keep the sale instead of losing it. Launch a preorder in minutes: the Preorder button automatically replaces 'Sold Out,' then charges full payment or a deposit and auto-collects the balance later. Add delivery dates, badges, and 'only X left' urgency to build trust, and set per-product or campaign caps to prevent overselling. For sold-out items you're not preselling, capture emails and send back-in-stock alerts automatically when you restock.
