What is the inventory management system of Amazon warehouse and how does it work for sellers?

At its core, what is the inventory management system of Amazon warehouse? Amazon’s fulfillment network is built on a sophisticated tracking system that monitors every unit from arrival to shipment. When you use Amazon inventory services like Fulfilled by Amazon (FBA), your products are stored in Amazon’s warehouses, scanned into the system, and tracked in real time. This ensures accurate stock counts, rapid order fulfillment, and automated updates to your Seller Central dashboard.

There are two primary inventory management models on Amazon:

• Fulfilled by Amazon (FBA): You ship your products to Amazon warehouses, and Amazon handles storage, shipping, returns, and customer service. FBA offers Prime eligibility and access to Amazon’s logistics power.
• Fulfilled by Merchant (FBM): You store inventory yourself and ship orders directly to customers. FBM gives you more control but requires robust in-house logistics.
