If you’re new to Amazon and are trying to grow your business, it can be confusing trying to understand all of the jargon and acronyms involved with selling your products. We’ve compiled a list of the most commonly used amazon seller acronyms you’re likely to encounter on your journey of selling. Some of these might be more applicable to you than others, but we think it’s good to understand what they mean anyway.
