I want to share some information about the SKU, sales-wwspree.
In QuickBooks Online, SKU is used to identify and track the inventory. Each item has a unique SKU code. This helps classify the characteristics of each product, such as manufacturer, brand, style, color, and size. For example, the SKU for a green v-neck shirt, size 10, may read "VN-GRN-10".
If you create the same item with the same SKU, this is unavailable in QuickBooks Online. You'll want to check out for a third-party application that has the capability of recording the same item and SKU.
