How should I correct inventory?

The easiest way to correct a group's stock is to set it directly from the Groups page in the app. Open the group, choose Adjust, and enter the quantity you want the group to have. SKU Stock Sync applies that quantity across the group's members for you.

If you'd rather make the change in Shopify instead, you can also correct inventory by updating one variant in the group to the quantity you want.

Warning: If you're correcting inventory in Shopify rather than using Adjust, do not update every variant in the group to the same quantity manually. SKU Stock Sync may treat each manual change as a separate inventory change, which can cause the changes to be combined.

Why you should only update one variant (Shopify method)

SKU Stock Sync treats variants in the same SKU/location group as sharing the same stock.

When you change inventory for one variant, SKU Stock Sync can use that change to update the other variants in the group.

If you manually update multiple variants before SKU Stock Sync processes the group, the app may see multiple inventory changes for the same shared stock.

Info: For example, if two variants are at stock 0 and you manually change both to 10, SKU Stock Sync will see multiple increases instead of one correction. Using Adjust on the Groups page avoids this altogether, since you're setting one value for the whole group directly.

Correct approach in Shopify

1. Choose one variant in the group: Pick one variant that belongs to the SKU/location group you want to correct.
2. Update that variant only: In Shopify, change that one variant's inventory to the quantity the group should have.
3. Wait for SKU Stock Sync to process the group: SKU Stock Sync will process the related group during a scheduled sync, or sooner with manual sync.
4. Check the result: After the sync runs, check the other variants in the group to confirm they were updated.

Example

If a synced group should have stock of 10:

• Easiest: open the group on the Groups page and use Adjust to set it to 10.
• Correct (Shopify): update one variant in the group to 10, then let SKU Stock Sync update the rest.
• Incorrect: update every variant in the group to 10 manually.

If you already updated every variant

If you already changed every variant in the group, wait for the next sync to finish and check the final quantity.

If the final quantity is not what you expected, correct the group again using Adjust on the Groups page, or by updating one variant only to the desired quantity.

New variants take the group's stock

A variant that has just been added is different. Until SKU Stock Sync has synced it for the first time, it has no stock of its own to contribute: it takes its stock from the group it joins.

So if you create a product or variant and then set its stock, that number is not applied to the group. The next sync sets the new variant to whatever the group already holds, and the number you typed is replaced.

Info: This is what keeps a new variant from dragging its group's stock up or down. A variant created holding 0, or holding whatever quantity you happened to enter, would otherwise be read as a change to the shared stock.

To give the group a different stock level, set the group itself:

• Easiest: open the group on the Groups page and use Adjust.
• In Shopify: update one existing variant in the group, not the new one.

Once the new variant has been synced once, it stops being treated as new and behaves like any other member of its group.
