While using the Variant Dependent Method of Custom Pricing, if your product or variant inventory is updated within Shopify, it can take some time before Custom Pricing is able to recognize these updates. As well, there may be other apps or actions taken on the site that cause this inventory to become out of sync.
Manually syncing the inventory within Custom Pricing updates the app's inventory numbers immediately.
To manually sync inventory in Custom Pricing, while using the Variant Dependant Method, please follow these steps:
From within Custom Pricing, select Settings, then General.
Select Manually Sync Inventory.
Note If you are using Custom Pricing with the Draft Order or Accelerated Method, this feature is not available. For more information on the differences between each method, please visit Discount Methods and How to Switch.
