Everything you need to stop stockouts

Real-time low & out-of-stock alerts

Get notified by email, Slack, or WhatsApp the instant inventory crosses your threshold — before you lose the sale.

Automatic back-in-stock notifications

Let shoppers sign up on a sold-out product page and get notified automatically the moment it's restocked.

Auto-hide & auto-republish

Sold-out products are hidden from your storefront automatically, then brought back live the instant they restock.

Per-product thresholds & filtering

Set a global low-stock threshold store-wide, fine-tune it per product, or scope monitoring by collection and tag.

Stock-out predictions

See which products are projected to sell out within 7 days, based on your real sales velocity.

Analytics dashboard

Track alert history, stock-out trends, and webhook health across your catalog — plus daily or weekly digest emails.

Klaviyo integration

Send low-stock and back-in-stock events straight into Klaviyo to power real marketing flows and segments.

Native Shopify Flow triggers
