About this Product
When a product hits zero inventory, Shopify's default behavior is to hide the Add to Cart button or let it oversell silently — and you lose the demand you worked hard to create. The Pre-Order & Backorder Manager is a build-to-order Shopify app that turns stockouts into captured revenue instead of bounced visitors.
This is not an instant App Store download. ECOSIRE builds the app against your exact theme, product taxonomy and fulfillment workflow, installs it on your store via a custom OAuth app with the least-privilege scopes it needs (read_products, write_inventory, read_orders, write_orders, read_locations), and configures it around your real catalog before handover.
Under the hood it reads live stock from the Admin GraphQL API across all your multi-location inventory, and subscribes to inventory_levels/update and products/update webhooks so pre-order and backorder states flip automatically as stock crosses the thresholds you set — no manual tagging. Per-variant settings (pre-order vs backorder, deposit percentage, expected-ship date, queue cap) are stored in metafields under a dedicated namespace, so your data stays portable and survives theme changes.
On the storefront, a theme-aware App Embed / app block swaps the buy button for a Pre-Order or Backorder call-to-action, shows the expected-ship date, and supports deposit / partial payments so customers can reserve now and settle the balance before dispatch. Incoming reservations land in a backorder queue that allocates incoming stock first-come-first-served, and customers get automated restock and ship-confirmation emails as their order moves.
You own the result. ECOSIRE delivers the build, documents it, and supports it on an agreed plan.

Who this is for
DTC brand with frequent stockouts
A direct-to-consumer brand whose hero products sell out faster than they can restock, and who is currently losing demand every time the buy button disappears. They want to keep capturing orders — and cash via deposits — while inventory is in transit.
Made-to-order or small-batch maker
A maker who produces in batches or on demand and genuinely needs lead time. They need honest expected-ship-date messaging and a fair backorder queue so customers know when their item ships and orders are fulfilled in the right order.
Operations / fulfillment lead
The person responsible for not overselling across multiple locations and for getting incoming stock to the right customers first. They want automatic state switching, multi-location thresholds and a clear queue instead of manual tagging and spreadsheets.

Frequently Asked Questions about Pre-Order & Backorder Manager
Is this an app I download instantly from the Shopify App Store?
No. This is a build-to-order app. ECOSIRE builds it against your specific theme, catalog and fulfillment workflow, then installs it on your store via a custom OAuth app with least-privilege scopes. There is no public App Store listing — you receive a solution configured for your store, not a generic download.
How long does delivery take after I purchase?
Typical delivery is about one working week from the kickoff call, depending on your theme complexity, payment/deposit setup, number of fulfillment locations and any 3PL/ERP integration. After purchase we schedule a scoping call, agree the configuration, then build, install on a development or staging context where possible, and hand over. You'll get a clear timeline before work starts.
How do deposits and partial payments actually work?
We configure the deposit flow against your existing Shopify checkout and payment provider so a customer can pay a percentage to reserve a pre-order, with the balance collected before dispatch. The exact mechanism depends on your payment setup and plan; we confirm what's supported on your store during scoping rather than promising a one-size-fits-all flow.
Will it work with my multiple inventory locations and not oversell?
Yes. The app reads live stock across your locations through the Admin GraphQL API and listens to inventory and product webhooks, so pre-order and backorder states switch automatically as stock crosses the thresholds you set per variant. The backorder queue then allocates incoming inventory first-come-first-served so reservations are honored in order.
What happens after launch — do I get support and updates?
Yes. Handover includes documentation and a walkthrough, plus an agreed support and maintenance plan. Because the app talks to the Shopify Admin API and webhooks, ECOSIRE maintains compatibility as Shopify versions its API, and handles fixes, threshold/messaging changes and enhancements under your support plan. You own the delivered app.
