Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featurePreorder Back In Stock adds a preorder button or a Notify me when available waitlist to every sold-out product, without touching your theme. Run campaigns with full or partial-deposit payments, percent or fixed discounts, scheduled start and end, variant and collection targeting, and per-campaign translations. Back-in-stock subscribers are emailed when inventory hits your threshold.
Tired of apps that fail silently on a big restock, or charge a cut of your pre-order revenue? Restocker is built differently. Shoppers join a waitlist and get an automatic email the moment you restock. Pre-orders use native Shopify selling plans, so Shop Pay cannot oversell you. Every notification writes to a permanent delivery log: not just "sent" but actually delivered.
