You're losing sales opportunities.
The moment a product sells out, sales stop — and customers waiting for restock drift away.
Out of stock or not yet launched? Don't let it end in a missed sale.
Manage pre-orders, made-to-order, waitlists, and purchase limits in one place — and reduce lost sales on Shopify.
- Theme App Embed integration
- Waitlist & notification management
- Purchase limits supported
Running into these issues on Shopify?
From announcement to sale, it's all manual.
Even when you announce upcoming products, building a path to pre-order purchases is done by hand.
Order management is a mess.
You want to offer made-to-order products, but complex shipping notifications and order tracking make it impossible to keep up.
If nothing changes, you may be leaving demand on the table.
- Every time a product goes out of stock, you lose a sales opportunity.
- The process from announcing to pre-selling is entirely manual.
- There's no follow-up with customers waiting for restocks.
- Managing made-to-order listings and pre-order logistics is overwhelming.
- You worry about missed notifications and forgotten settings.
