1. Overall Picture of Seller Central: Control Tower of Marketplace

Seller Central is an integrated platform for companies selling on Amazon to perform daily operations. Its biggest feature is in "Scalability" and "Data Transparency" . Advanced sales management is possible on the same foundation from small individual business owners to national clients handling tens of thousands of SKUs.

Comparison of major roles is divided into 4 areas: catalog creation (listing), fulfillment (shipping setting), customer service, and payment management. By centrally managing these, front-end sales activities and back-end logistics can be synchronized.

2. Functional Explanation of Major Modules: Inventory, Price, Catalog

The most frequently used tabs in Seller Central are "Inventory" and "Pricing". Detailed settings per SKU are required here.

Especially maintenance of "Inventory Health" is directly connected to organic search ranking within Amazon and storage limits, so managers are required to watch "Inventory Performance Index (IPI)" daily and minimize dead stock.

3. Utilization of Business Reports: Data Analysis Supporting Decision Making

The true value of Seller Central lies in the huge accumulated sales data. In the "Business Reports" section, KPIs such as session count, unit session percentage (CVR), and average sales price can be extracted daily, weekly, and monthly.

Since it can immediately identify whether the problem lies in "lack of traffic" or "decline in conversion rate" when sales are sluggish, high-speed PDCA cycle based on Facts can be run.

4. Operational Efficiency: Importance of API Cooperation and Automation

When business scale expands and reaches the stage of processing thousands to tens of thousands of orders, manual operation of Seller Central reaches its limit. What becomes important here is cooperation with external ecosystems utilizing Amazon SP-API.

By introducing inventory synchronization systems and Order Management Systems (OMS), it becomes possible to prevent inventory discrepancy (OOS: Out of Stock) in multi-channel sales and realize operational excellence.
