fbr meaning stands for Fulfillment by Retailer, a service where retailers handle the fulfillment process for their own products, rather than outsourcing to Amazon. This differs from Fulfillment by Amazon (FBA), where Amazon takes care of the storage, packing, and shipping of products. Retailers who use FBR manage their own warehouse and logistics operations. FBR can be beneficial for businesses that want full control over their fulfillment process, but it typically requires more infrastructure and resources compared to using FBA.
