Back-in-Stock Alerts

Hauptfunktionen

Per-variant waitlist signup that respects size, color, and option selection rather than capturing demand at the parent-product level

Embedded signup widget delivered as a Theme App Extension so it survives theme updates and matches your brand styling

Automated restock notifications across three channels: transactional email, SMS, and web push

Real-time restock detection via Shopify inventory_levels/update and products/update webhooks

Multi-location inventory awareness — only fires when tracked locations actually have sellable stock

Direct add-to-cart / checkout links in every notification to shorten the path from alert to purchase

Waitlist demand analytics: deepest-demand variants, notifications sent, click and conversion rates, and recovered revenue

Configurable send rules — instant on restock, throttled batches, or low-stock-aware to avoid notifying more shoppers than units available

Customer and variant data stored via Shopify metafields and the Admin GraphQL API, owned entirely by your store

Least-privilege OAuth scopes (read_inventory, read_products, read/write to app-owned data) with no broad write access to your catalog

Optional double opt-in and unsubscribe handling to keep email/SMS sending compliant

Admin dashboard to review, export, or manually trigger waitlist sends per variant

Über dieses Produkt

Every sold-out product page is a leak in your funnel. A shopper who wanted to buy hits "Out of stock," leaves, and rarely comes back — even after you restock. Back-in-Stock Alerts closes that leak by turning the moment of disappointment into a captured lead and an automatic recovered sale.

This is a build-to-order Shopify app — ECOSIRE designs, develops, installs, and supports it for your specific store. It is not a one-click App Store install. After purchase we scope your theme, locations, and notification channels, then build a private app tailored to your catalog and brand.

The app embeds a per-variant waitlist widget on product pages via a Theme App Extension, so signups respect size/color/variant selection rather than the parent product. Captured demand is stored against the customer and variant, and the app subscribes to Shopify's inventory_levels/update and products/update webhooks. When a variant's available quantity crosses zero across your tracked multi-location inventory, queued subscribers are notified automatically — by email, SMS, and web push — with a direct add-to-cart or checkout link.

Under the hood it uses OAuth with least-privilege scopes, the Admin GraphQL API to read inventory and variant data, and metafields to persist waitlist configuration. A back-office demand analytics view shows which variants have the deepest waitlists, conversion rate per restock send, and revenue recovered — giving merchandising and purchasing teams a real signal for what to reorder.

You own the app and the data. Because it's purpose-built, there are no per-subscriber SaaS fees stacking up as you grow, and the notification logic bends to your workflow instead of the other way around.

Für wen das ist

DTC brand owner losing sales to stockouts

Runs a fast-moving apparel or consumer-goods store where popular variants sell out between restocks. Wants to capture interested shoppers at the exact sold-out moment and pull them back automatically when inventory returns, without paying escalating per-subscriber SaaS fees.

Ecommerce / merchandising manager

Owns conversion and reorder decisions. Needs hard demand data — which variants have the longest waitlists and what each restock send actually recovers in revenue — to justify purchasing quantities and prioritize what comes back in stock first.

Shopify store operator on a custom or heavily-themed storefront

Has an off-the-shelf alert app that clashes with their theme, can't target variants correctly, or sends at the wrong moment. Wants a back-in-stock flow built to fit their exact theme, locations, and notification stack instead of bending their store to a generic widget.

Häufig gestellte Fragen zu Back-in-Stock Alerts

How long does it take to build and install after I purchase?

Typical delivery is about 10 to 15 business days from the kickoff call, depending on the number of notification channels, theme complexity, and how many locations you track. After purchase we scope your store, build the private app, install it via OAuth, embed the widget, and run end-to-end restock tests before handover. We confirm a firm timeline during scoping — this is a build-to-order app, not an instant App Store download.

Do I get ongoing support and updates after launch?

Yes. Every build includes a post-launch support window to fix issues and tune the notification rules once real traffic flows. Beyond that, we offer ongoing maintenance to keep the app working against Shopify API version changes, theme updates, and your evolving catalog. Because you own the app, you're never locked into a subscription to keep your existing waitlists running.

Will the signup widget break when I update my theme?

No. The widget ships as a Theme App Extension, which Shopify renders through app blocks rather than hard-coded theme edits. That means it persists across theme updates and theme swaps, and you can position and style it from the theme editor without touching the app code.

Does it handle stores with multiple inventory locations?

Yes. The app reads available quantities across your locations through the Admin GraphQL API and listens to inventory_levels/update webhooks. You choose which locations count as sellable, and notifications only fire when those tracked locations actually have stock a customer can buy — so warehouse transfers or unfulfillable locations don't trigger false restock alerts.

What happens to my waitlist and customer data — who owns it?

You do. All waitlist signups, customer associations, and configuration live in your store via metafields and app-owned data using least-privilege OAuth scopes. You can export the data at any time, and nothing is held hostage behind a third-party SaaS account. We never use broad catalog write access we don't need.

Can it avoid notifying more shoppers than I have units in stock?

Yes. Send rules can be configured to be stock-aware — for example, throttling or batching notifications so you don't blast a 500-person waitlist when only 20 units came back. This protects the customer experience and keeps your email and SMS sending reputation healthy.
