Never lose a sale to "out of stock" again.
Stockouts lose the sale forever — unless you capture it. RestockFlow is one Shopify app for pre-orders with partial deposits, back-in-stock email + SMS, and waitlist analytics. One app instead of three, from $24/month.
Why RestockFlow
Merchants juggle a pre-order app, a back-in-stock app, and an SMS app — three bills, three waitlists that don't talk to each other.
Take the deposit, not just the email
Pre-orders with full or partial deposits per product — 20% now, the rest on ship. Cash flow before the restock, not just a hope.
One app instead of three
Pre-orders, back-in-stock emails, and SMS alerts share one waitlist and one analytics view. One install, one bill.
Know your demand before you reorder
Waitlist signups per SKU roll up into a demand score, so you restock what people actually want — not what you guess.
Built for the viral moment
When TikTok empties your shelves mid-spike, the waitlist is already capturing every lost sale. Restock alerts fire the moment inventory returns.
Plans from $24/mo
