Documentation

Everything you need to set up and get the most out of Stock Alert.

Getting started

Install Stock Alert from the Shopify App Store and it starts syncing your product and inventory data immediately. Every plan includes a 7-day free trial and no credit card is required to start it.

Click Add to Shopify and approve the requested permissions.
Pick a plan (Basic, Professional, or Enterprise) — you can change this later from the app's Billing page.
Set a store-wide low-stock threshold, or leave the default while your sales data syncs.
Choose which channels should receive alerts: email, WhatsApp, and (on Professional+) Slack.

Stock thresholds

A global threshold applies to every product by default — once available inventory drops to or below that number, Stock Alert fires a low-stock alert. On Professional and Enterprise plans you can override the threshold per product, or scope monitoring to specific collections and tags, instead of applying one number store-wide.

Notification channels

Alerts go out the instant inventory crosses your threshold, before the sale is lost:

Email — included on every plan.
WhatsApp — included on every plan.
Slack — one-click Slack Connect, available on Professional and Enterprise.
Multiple recipients and white-label branded emails — available on Professional and Enterprise.

Auto-hide & auto-republish

Sold-out products are automatically hidden from your storefront on every plan, so shoppers never land on a page they can't buy from. On Professional and Enterprise, Stock Alert also auto-republishes the product the instant it's restocked — no manual re-listing needed.

Back-in-stock widget

Add the back-in-stock signup widget to any sold-out product page. Shoppers who opt in are emailed automatically the moment the product restocks — collected with explicit consent and used only for that single notification.

Predictions & analytics

The analytics dashboard tracks alert history, stock-out trends, and webhook delivery health across your catalog, and surfaces which products are projected to sell out within 7 days based on your real sales velocity. Daily or weekly digest emails summarize this for you without needing to check the dashboard.

Integrations

Available on Professional and Enterprise:

Klaviyo — send low-stock and back-in-stock events into Klaviyo to power marketing flows and segments.
Outbound webhooks — pipe every alert into Zapier, Make, or your own ERP.
Asana — automatically create a task for stock events you map.
Shopify Flow — native triggers on low-stock, out-of-stock, and restock events, no code required (included on every plan).

Suppliers & purchase orders

Enterprise adds supplier management: record vendor lead times, get reorder-point recommendations calculated from those lead times, and generate purchase orders directly from a low-stock alert. Enterprise also unlocks dead stock alerts and Core vs. Limited-Edition report sections in analytics.

FAQ

Do I need a credit card to start my trial?

No — every plan includes a 7-day free trial with no credit card required to start it.

What happens to my data if I uninstall?

Shopify sends us a shop/redact webhook within 48 hours of uninstall, which permanently deletes all of your store's data from our systems — see the Privacy Policy for details.

Can I switch plans later?

Yes, you can upgrade or downgrade at any time from the app's Billing page.
