A shopper lands on your best collection, sees a "Sold Out" badge in the first row, and leaves. Your ad spend just paid for a visit to a product nobody can buy. Out-of-stock products at the top of a collection lower your conversion rate, and Shopify does not reorder them for you.

🎯 Quick Summary

  • Shopify has no native way to auto-push sold-out products to the bottom of a collection.
  • Leaving them at the top frustrates shoppers and can result in lost sales.
  • Sortello's Pro plan pushes them down automatically in real time, then moves them back up when they restock.
  • The Free plan gives you a one-click manual push whenever needed.

⚡ Real-Time Auto-Push: Move Sold-Out Products Away from the Top

In the default Shopify experience, a product remains in its existing position after it sells out. If it remains at the top, it can displace in-stock products. Shopify does not provide a native option to sort products by inventory quantity.

The manual fix is to drag it down in the editor. Shopify's drag-and-drop only works within the page you are viewing, so in a collection of 200+ items, moving a product from near the top to near the bottom means paging through the whole list one screen at a time. It does not hold up as a routine you run every time something sells out.

Sortello's Pro plan watches your inventory in real time. When a product hits zero stock, it moves to the bottom of the collection within seconds. No manual drag, no paging through the list.

This matters because collection order directly affects how much of your inventory shoppers see. Shoppers rarely scroll past the first row on mobile. If that row is full of "Sold Out" badges, fewer shoppers will reach products they can purchase.

🔄 Auto-Restore: Restore Products When Stock Returns

A complete solution also needs to restore products when inventory returns. Without automatic restoration, a restocked product remains at the bottom of the collection or must be moved manually through Shopify's editor.

When stock returns, Sortello re-sorts the collection so the product moves back to its proper place: its spot in your manual order if you arrange collections by hand, or its rank under whatever sort rule you use. Either way, it does not stay stranded at the bottom, and you do not touch it.

Works the same on mobile.

This is especially useful if you run automated sort rules across your collections. Pair auto-push and auto-restore with a best-seller sort by recent sales velocity, and your collections show the right products in the right order on their own.

💡 Pro tip: Combine auto-push with Sortello's tag-based pins (Pro) to keep your hero products locked at the top while everything else sorts itself.

🚀 Why Every Store Should Fix This

Sold-out products at the top of your collection are more than a presentation issue. They represent real money: shoppers who landed, saw something unavailable, and left. If you've been thinking about how to handle out-of-stock products on Shopify, fixing their collection position is the first and cheapest thing you can do.

Shopify will not sort by stock status on its own. The Free plan gives you a one-click manual push whenever you need it. Pro is $9.99 a month, makes it automatic, and moves products back up on restock. Paid plans include a 7-day free trial.

Frequently Asked Questions ❓

Open your Shopify admin, go to Products > Collections, and use the Sort dropdown to pick Best Selling, Newest, Price, or Alphabetical. For a custom order, set it to Manually and drag products into position. The catch: drag-and-drop works only within the page you are viewing. For larger collections or automatic sorting, Sortello adds one-click sort rules and handles up to 5,000 products per collection.
It is a built-in Shopify limitation. The admin shows one page of products at a time, so drag-and-drop is confined to whatever is currently visible. Moving a product from the first page to the eighth means dragging it through each page in turn. Sortello's editor supports multi-select and lets you reposition products anywhere across the full collection in a single action.
Not natively. Shopify does not save previous sort orders, so once you rearrange a collection the prior arrangement is gone. Sortello keeps a sort history with up to 20 saved snapshots per collection. You can restore any previous arrangement with one click.
No. Shopify has no native option to sort by inventory status or quantity, so sold-out products stay wherever they fall in your current sort. Sortello's Pro plan adds real-time auto-push: the moment a product hits zero inventory, it moves to the bottom automatically.
With Sortello Pro, yes. When stock returns, the collection re-sorts so the product moves back to its place: its spot in your manual order, or its rank under your sort rule. Without this, a restocked product stays wherever it was pushed, at the bottom and out of view.
Indirectly, yes. Sold-out products at the top of a collection raise bounce rates and reduce time on site, both signals search engines use to judge relevance. Keeping in-stock products prominently displayed improves the shopping experience. For a deeper look, see how sold-out products affect your Shopify SEO.
The auto-push logic works with both collection types. Automatic collections control which products appear based on rules (such as product tags or vendor), but the order of those products is a separate setting. You need the collection sort set to Manual for a script to reorder products, and that is fully compatible with automatic collections.
Pre-order products are a common exception. You can tag them (for example, with a pre-order tag) and configure the sort logic to skip those tags, so they keep their position even at zero inventory while other sold-out products still get pushed down. A CartWorks developer can build that exception into the automation for your store.
