Selling on Amazon comes with its own language—and if you’re new to the platform, acronyms like FBA, BSR, ACOS, and ROI can feel overwhelming. Understanding these terms is essential because Amazon uses them in dashboards, reports, and policy notices. When you know the language, you can make faster, smarter decisions as a seller.
These acronyms aren’t just technical jargon—they directly affect your profitability, account performance, advertising strategy, and even product visibility. Sellers who ignore them often waste ad spend, misread performance metrics, or risk account flags simply because they misunderstood a term.
This glossary-style guide will walk you through the most important Amazon acronyms every seller should know. Whether you’re just starting or are actively scaling your store, mastering these terms will give you the edge you need to navigate Amazon like a pro.
Why Amazon Acronyms Matter for Sellers
Amazon operates on its own ecosystem with specific policies and technical workflow terms. When Amazon sends notifications about your ASIN status or flags your account due to a late ODR rate spike, you should be able to interpret these alerts instantly. Many sellers lose time—and revenue—simply because they misunderstand what certain alerts and dashboard terms mean. Knowing these acronyms is part of being a proactive and strategic Amazon seller.
Amazon documentation, policies, and even support tickets heavily rely on abbreviations. If you’re serious about performance metrics, FBA logistics, ad optimization, or brand protection, familiarizing yourself with the glossary will help you move faster and make better decisions. Treat this glossary as your go-to reference to speak Amazon’s language with confidence.
Core Selling and Inventory Acronyms
ASIN (Amazon Standard Identification Number)
Every product listed on Amazon gets an ASIN, which acts as a unique catalog identifier. Understanding ASINs is crucial when optimizing listings, managing variations, or checking product authenticity. When a product gets flagged or hijacked, Amazon’s system always references the ASIN.
Sellers often overlook the importance of protecting their ASINs. Monitoring hijackers and ensuring consistent branding becomes easier once you know how to manage ASIN-level reports. ASIN tracking also helps with keyword ranking insights and Buy Box performance.
SKU (Stock Keeping Unit)
SKU codes are created by sellers for internal tracking. While Amazon uses ASINs, your warehouse or virtual inventory management relies on SKUs. A smart SKU naming structure speeds up restocking, order fulfillment, and even financial reporting.
Crafting strategic SKUs prevents confusion when running multiple FBA and FBM listing variations. It also improves tracking during peak seasons or special campaigns like Prime Day and Q4 shopping surges.
Fulfillment and Logistics Acronyms
FBA (Fulfilled by Amazon)
FBA means Amazon handles storage, packing, shipping, and delivery—a powerful service that increases Buy Box chances and qualifies products for Prime. However, it also comes with fees and inventory requirements that sellers must understand clearly.
Sellers using FBA must manage inbound shipments, restock limits, and storage fees. Understanding FBA metrics helps reduce long-term storage charges and improves inventory turnover rates.
FBM (Fulfilled by Merchant)
FBM sellers manage their own shipping and customer service. This model gives more control but demands strong logistics and fast response times to maintain seller ratings. Many hybrid sellers use both FBM and FBA strategically to manage risk during inventory delays.
Switching to FBM temporarily can also be a rescue strategy if FBA restock limits are reached or fulfillment centers experience delays. Smart sellers prepare backup FBM listings ahead of time.
Advertising and Performance Acronyms
PPC (Pay-Per-Click)
Amazon PPC ads charge sellers every time a shopper clicks on their promoted listing. These ads appear in search results and product detail pages, helping increase visibility and ranking. Effective PPC management requires monitoring ACOS, CTR, and CPC regularly.
Running PPC without understanding its related acronyms often leads to wasted ad spend. Optimizing match types, negative keywords, and bid strategies can significantly improve your advertising ROI.
ACOS (Advertising Cost of Sales)
ACOS measures how much advertising spend you used to generate a sale. Lower ACOS typically means better profitability. However, in ranking campaigns, a temporarily higher ACOS may be acceptable to gain organic keyword positions.
Balancing ACOS with TACoS (Total Advertising Cost of Sales) gives a more holistic view of advertising impact. Smart sellers assess both to determine whether ads are fueling organic growth or merely sustaining paid sales.
Customer Metrics and Account Health Acronyms
ODR (Order Defect Rate)
ODR is a critical health metric that tracks negative feedback, A-to-Z claims, and service issues. A high ODR can risk account suspension. Sellers must respond quickly to disputes and customer messages to keep ODR within safe limits.
Monitoring ODR daily helps you react before account health warnings escalate. Amazon prefers preventive action, and early intervention can save your store from costly enforcement actions.
VOC (Voice of the Customer)
VOC is Amazon’s customer sentiment dashboard, showing positive and negative product feedback trends. It gives insight into packaging issues, product defects, or listing miscommunication. Healthy VOC scores enhance listing trust and help avoid returns.
Proactive sellers use VOC insights to improve product descriptions, modify packaging, and enhance customer satisfaction. Amazon rewards listings with high VOC through better visibility.
Amazon Support and Compliance Acronyms
POA (Plan of Action)
A Plan of Action is required when your account or listing is deactivated. Amazon expects a structured explanation: what caused the issue, what actions you’ve taken, and how you will prevent it. A well-written POA can restore selling privileges faster.
Knowing how to draft a strong POA reduces downtime and demonstrates professionalism. Poorly written POAs often lead to more delays or outright rejection from Amazon’s compliance teams.
IPR (Intellectual Property Rights)
IPR violations often result from counterfeit claims or copyright infringements. Even when unintentional, these violations impact account trust. Secure trademarks, brand registry, and keep documentation for all your suppliers to protect against IPR claims.
Registering your brand through Amazon Brand Registry improves listing control and prevents unauthorized edits. IPR protection is essential for long-term brand positioning.
More Essential Acronyms Every Amazon Seller Should Know

| TOS | Terms of Service | Violations risk suspension |
| LTSF | Long-Term Storage Fees | Impacts FBA profitability |

Final Takeaway for Amazon Sellers
Mastering these acronyms gives you a competitive edge. Instead of feeling overwhelmed by Amazon’s dashboard and performance alerts, you’ll understand exactly what each metric indicates and what steps to take. Small details like knowing how ACOS affects TACoS or why ODR spikes matter can protect your store from penalties and improve your long-term sales performance.
As you continue your Amazon selling journey, revisit this glossary frequently. The more fluent you become in Amazon terms, the easier it will be to scale efficiently, optimize your listings, and protect your account from compliance issues.
