Introducing Our All-New Integration: Cross Sell & Upsell x Back In Stock

We've teamed up with the Back In Stock app to give your customers more control, more options, and more reasons to shop again. When a product is sold out, your customers can now:

  • Easily sign up for a back-in-stock alert
  • Browse and purchase related products and upsells
  • Do both—from the same page!

If you're using both Cross Sell & Upsell and Back In Stock, this enhanced integration is ready to roll—no extra costs involved. It’s the perfect way to increase conversions without increasing your spend.

Why This Integration Matters for Your Shopify Store

The moment a shopper subscribes to a back in stock alert is when their intent is highest. With this integration, you can now show them frequently bought together products and personalized upsells right then and there—before they even leave the page.

Here’s what your customers can do:

  1. Discover and purchase related items or upsell offers directly on the sold-out product page
  2. Sign up to be notified when their desired item is back in stock

It’s a win-win. You recover lost sales, increase average order value (AOV), and keep your Shopify store top of mind.

What’s In It for You?

  • Higher customer engagement: Keep shoppers interacting with your store—even when items are out of stock
  • Increased sales: Drive more upsell conversions by showcasing complementary products at just the right time
  • Effortless setup: All paid users of both apps get access at no additional cost
  • More returning customers: Stay in your customers’ inbox—and on their shopping lists

How It Works for Your Customers

It’s simple and smooth:

  • A shopper visits a sold-out product page and clicks the “Notify me when available” button
