Prelude ‑ Waitlist & Demand

See what shoppers want before you buy stock. A waitlist for sold-out products, by variant.

Prelude adds a waitlist button to your sold-out and coming-soon products. Shoppers pick the exact variant they want and leave an email. No account, no card, no payment taken. Every signup lands in your Shopify admin grouped by vendor, product and variant, ranked by demand, so you know what to make or reorder, and how much, before you spend on stock. Daily summary by email, filters by vendor, product or date, and CSV export for your supplier. Matches your theme. Removes its data after uninstall.
