When setting up a Seller SKU in Seller Central, it is crucial to assign a distinctive SKU name to your listing. Otherwise, Amazon will automatically use your product title as the SKU name. Be cautious, as certain abnormal symbols in the product title can lead to BQool being unable to update your product information. To ensure smooth operations, carefully choose a unique SKU name during the initial setup.

Additionally, it's important to note that the system does not distinguish between upper and lower case in SKU names. Therefore, it is advised not to utilize uppercase and lowercase variations in SKU names to differentiate between two distinct listings. From the system's perspective, these variations are considered the same SKU, potentially leading to inaccuracies in reflecting quantity data. To ensure proper representation, avoid relying on case sensitivity in SKU differentiation.
