syncX: Preorder & Back In Stock

Turn "Sold Out" Into "Still Selling."

Keep revenue flowing when inventory runs dry. Accept preorders, capture waitlist signups, and notify customers automatically — all inside your Shopify store.

Shopify-native preorder + back-in-stock app for D2C, B2B or hybrid merchants.

When "Out of Stock" means lost opportunity.

Enough with unsuccessful campaigns that cost you money and give back nothing. Get a simple solution that helps you weaponize your performance data.

❗ "We sell out every drop but can't collect preorders."
❗ "Back-in-stock requests live in spreadsheets."
❗ "We lose cashflow during restocks."
❗ "Wholesale buyers can't place advance orders."

Everything you need to keep revenue — and trust — steady.
