No. This is a build-to-order extension. ECOSIRE develops the module, then installs it on your own Magento 2 / Adobe Commerce environment and tailors it to your theme, MSI configuration, and purchase-order workflow. You receive a tested, production-ready install — not a generic Marketplace zip you have to integrate yourself.

Typical turnaround is about 2 to 3 weeks from kickoff for a standard build on a healthy Magento install: requirements confirmation, development, your review on staging, then production install. Heavy theme customization, complex multi-source MSI setups, or bespoke purchase-order data sources can extend this. We confirm a firm timeline before starting.

The build includes installation, smoke testing, and a handover, plus a warranty window for fixing any defects in the delivered scope. Beyond that, we offer ongoing support and compatibility maintenance (for new Magento / Adobe Commerce minor and security releases) as a separate retainer or per-request engagement, so the module keeps working as your platform updates.

Yes. The module is MSI-aware: alerts fire when salable quantity returns above zero for the relevant stock, not just on a legacy in/out flag. Subscriptions target the specific child SKU of a configurable or grouped product, so a shopper waiting on one size or color is only notified when that exact option is back.

The expected-back date is driven by purchase-order / replenishment ETA data. During the build we connect it to the source you maintain — a PO field, an admin-entered date per SKU, or an imported feed. When that ETA exists for an out-of-stock item, the product page can display it; when stock actually returns, the inventory-event observers trigger the emails regardless of the displayed estimate.

Yes. The module exposes REST and GraphQL endpoints to create, query, and cancel subscriptions, so a PWA Studio or other headless frontend can offer the same notify-me experience. The dispatch, admin grid, and cron logic run server-side independently of the storefront technology.
