About RestockFlow

RestockFlow is a Shopify app for the two halves of a stockout: capturing the sale while you're out of stock (pre-orders, waitlists) and converting the demand the moment you're back (restock alerts).

We're in pre-launch. The flow engine — pre-orders with partial deposits, the notification queue, attribution, analytics, and the Shopify inventory webhook receiver — is built and tested (14 automated tests, all passing). Store onboarding is founder-operated while the App Store listing is prepared.

We don't do inventory planning or email marketing. We do the moment inventory returns — and the weeks before it.

What we won't do

We won't promise checkout customization on non-Plus stores (Shopify's limits apply, and we say so at checkout), we won't spam your waitlist (one reminder, then expiry), and we won't surprise-bill SMS overages.
