There might be scenarios on your Shopify store where the products added from Zendrop are showing to have 0 inventory. This can affect one or a few variants or the entire SKU in general.
To solve this please use the steps below:
Identify the product/variant for which you are facing this issue.
In your Shopify Admin head over to Products > Find the product you where this issue is happening > Open product
Scroll down until you see the variants with the 0 Available inventory. Select all variants from the indicated touch point and click Bulk Edit.
On the next screen click on the column icon in the top right corner and under Quantities by location make sure that Zendrop and your store's location are marked as check.
For all variants, ensure that Zendrop Available has the Stock at this location option enabled.
Now from your store's location copy the count and paste it into Zendrop-Available. This will update the count on the Zendrop side.
Drag the number down and update all the variants.
Click Save and you are good to go. You’re all set and the problem is now resolved!
Why do we have to take this approach:
Shopify allows third-party apps to manage inventories of the products. If inventory is being managed by a third party, it does not allow a user to go in and update the inventory. In this scenario, Shopify considers Zendrop as a similar app and does not allow changing the inventory.
Therefore taking this approach solves allows us to bypass that limitation.
