Backrow: Sold Out Last moves products that are sold out to the end of a collection, and moves them back when they are restocked. You turn it on per collection.

Getting started

How do I install the app?

Install it from the Shopify App Store and approve the permissions. The app opens inside Shopify admin (Apps > Backrow: Sold Out Last). It asks for access to products (to read and reorder collections) and to inventory (to read stock). It does not ask for access to customers or orders.

How do I turn it on for a collection?

1. Open the app. You see a list of your collections with their sorting and the rule state.
2. Click Turn on next to a collection.
3. If the collection is not sorted Manually, the app explains, right under the collection's row, that it will switch it to Manual sorting. Click Switch to Manual and turn on to continue, or Cancel.
4. The app saves the current order of the collection and moves sold-out products to the end. The row shows the rule as On and the result of the run (how many products were moved and how many are sold out).

Which collections are supported?

Collections where you pick the products yourself (manual collections). Smart collections, which add products automatically by conditions, are not supported at the moment and are listed as "Not supported (smart collection)". The app lists up to 1,000 collections.

How it works

Why does the collection switch to Manual sorting?

Shopify only allows an app to set the order of products in a collection when the collection is sorted Manually. So when you turn the rule on, the collection's sorting changes to Manual. The app remembers the previous sorting (for example "Best selling") and brings it back when you turn the rule off. Right after the switch, the products are in the same order as before; only sold-out products are then moved to the end.

When is a product treated as sold out?

When every variant of the product has inventory tracking on and has no stock available (0 or less) at any location (or at any of the locations you chose in the settings). A product is never moved to the end when:

• any of its variants does not track inventory;
• any of its variants is set to "Continue selling when out of stock" (you can change this, see below);
• it has a tag you excluded in the settings;
• the app could not read its full stock data (for example a product with a very large number of variants or locations). Such products are counted as "incomplete stock data" in the row.

What order do the other products keep?

The order the collection had when you turned the rule on. Products in stock keep that order, sold-out products follow in the same order, and a product that comes back in stock returns to its place. Products added to the collection later go to the end of the in-stock (or sold-out) group.

When does the order update?

• When you turn the rule on.
• When stock changes: after Shopify notifies the app about an inventory change, the app recalculates the collections that contain the product. It waits briefly so that several stock changes in a row are handled in one recalculation. The timing depends on when Shopify delivers the notification.
• When you click Recalculate now or save the rule settings. Use Recalculate now if the order has not updated yet.
• In a scheduled daily re-check, which recalculates every collection with the rule on. It catches stock changes the app missed and puts back products you reordered by hand in Shopify admin.

What does the daily re-check do?

Once a day, on a schedule, the app recalculates every collection where the rule is on. Collections it reorders, or fails on, appear in the activity log as "Nightly check"; collections already in order appear as one "Summary" entry per run.

Can I still reorder products by hand?

While the rule is on, the app keeps the order from when you turned it on. If you drag products in Shopify admin, the next recalculation (or turning the rule off) puts them back. To change the base order: turn the rule off, reorder the collection, and turn the rule on again.

What if I change the collection's sorting in Shopify admin?

If you change the sorting from Manual to something else while the rule is on, the app stops reordering that collection and shows "Sorting changed". Turn the rule off and, if you want, on again. In this case turning it off leaves the collection's order and sorting as they are.

Settings (per collection)

On a collection row, open the More actions menu (the "..." button) and choose Edit rule settings. The settings open right under the row. When the rule is on, saving updates the order right away; when it is off, the settings apply when you turn it on.

Exclude products by tag

In "Never move products with these tags", enter tags separated by commas (not case-sensitive). Products with any of these tags keep their place even when sold out.

"Continue selling when out of stock"

By default, a product with a variant set to continue selling when out of stock counts as available and is not moved. Uncheck "Treat products set to continue selling when out of stock as available" to judge such products by their stock like any other.

Count stock only at some locations

Under "Count stock only at these locations", enter the IDs of the locations to count, separated by commas; leave the field empty to count every location. To find an ID, open Settings > Locations in Shopify admin and click the location: the ID is the number at the end of the page address, for example …/settings/locations/12345678. Stock is checked per location, not added up: a product counts as sold out when none of the chosen locations has stock. If none of the products in the collection has stock data at any of the chosen locations, the app stops and moves nothing.

Turning off and uninstalling

How do I get my previous order back?

On the collection row, open the More actions menu (the "..." button) and choose Turn off and restore. The app puts the products back in the order the collection had when you turned the rule on (products added since then go at the end) and restores the previous sorting. The activity log shows the change.

What happens when I uninstall the app?

Turn the rule off for each collection before uninstalling. After uninstall the app no longer has access to your store, so it cannot restore anything: collections keep their current order and stay sorted Manually. You can change the sorting yourself in Shopify admin at any time.

Your store's data (access token, collection rules and settings, activity log) is deleted from the app's database in two steps. When you uninstall, Shopify notifies the app; if that notification confirms your store's domain, the app deletes the data right away. About 48 hours after uninstall Shopify sends a data deletion request, and the app deletes everything that is still stored. Until then the data cannot be used to change your store, because the app no longer has access to it. If you install the app again after the data was deleted, you start from scratch: all rules are off. Details: Privacy policy.

Does the app change my storefront?

No. It adds no code or scripts to your theme. It only changes the order of products in the collections where you turn the rule on.

Plans

The Free plan lets you turn the rule on for up to 3 collections. The Unlimited plan costs 4.99 USD per month and has no limit. It comes with a 7-day free trial. If you used this app in the last 180 days, Shopify gives you only the trial days you have left. Plans are billed by Shopify. The app shows your plan and how many collections use the rule, with a link to change your plan.

If you have not chosen a plan yet, the app still works: the free plan's limit applies, and a "Choose a plan" link above the collection list opens Shopify's plan page, where you can pick a plan. If you move to the free plan while using more collections than it includes, those collections keep working, but you cannot turn the rule on for another one until you are under the limit.

Activity log

Below the collection list, the activity log shows recent runs in which the app reordered a collection or tried to: time, collection, trigger (stock change, panel action, settings saved, nightly check), result, the number of products moved and details such as an error message.

It is not a complete history:

• stock changes that needed no reordering are not listed;
• if a stock change fails with the same error for the same collection again within an hour, it is listed once;
• daily re-check runs that needed no reordering are combined into one "Summary" entry;
• the app keeps the newest 100 entries and shows the newest 50.
