How to move sold-out products to the bottom of a Shopify collection

I'm Tyler, and I make LeDuc Sold Out Sorter. You can move sold-out products to the bottom of a Shopify collection by hand, but you have to do it every time something sells out or comes back. An app can do it automatically, which is what mine does.

The built-in way

Themes show a sold-out product with a "Sold out" label and leave it where it is. If a collection is sorted manually, you can drag products into the order you want, so you can drag sold-out ones to the end yourself.

The catch is that it's manual work. Every time a product sells out you move it down, and every time it's restocked you have to remember where it used to sit. On a store with many products and frequent sell-outs, that gets out of date quickly. Collections sorted automatically (best selling, newest and so on) can't be dragged at all.

With LeDuc Sold Out Sorter

Install the app from the Shopify App Store.
Manually sorted collections are sorted right away. For collections sorted another way, click Switch to manual and sort. The current order is kept, and the in-stock order follows the sort it had.
That's it. When a product sells out it moves to the bottom of every manually sorted collection within seconds, and returns to its old spot when restocked. Every collection is also re-checked every 30 minutes.
Optional: in the "In-stock order" column, pick how in-stock products are sorted per collection: best selling, newest, price or title. Sold-out products always stay last.
Optional: under "Never move products tagged", add tags to leave alone. pre-order and preorder are the defaults.
Optional: turn on hiding if you'd rather sold-out products disappear until they're back. It's off by default.

FAQ

Which products count as sold out?
Products whose variants can't be bought: inventory is tracked and at zero or below. Products set to continue selling when out of stock stay where they are.

Does it work on automatically sorted collections?
Shopify only lets apps reorder manually sorted collections. For an automated one, the app can switch it to manual in one click and keep its current order.

How much does it cost?
Free for 5 collections. Pro is $4.99/month with a 14-day trial, for all collections.

Do I need to edit my theme?
No. There's no theme code and no storefront script. It reorders the collection in Shopify, so it works with any theme.
