Compare Amazon FBA & FBM Models for Sellers in 2025
Choosing between FBA and FBM is one of the most important decisions for Amazon sellers in 2025. The way you fulfill orders can shape your costs, customer experience and long-term growth. Fulfillment by Amazon, or FBA gives access to fast shipping with Prime and takes care of storage packing and returns. Fulfillment by Merchant or FBM allows sellers to handle their own delivery process, giving more control over inventory and shipping costs. With new Amazon fee updates, rising storage charges and tighter performance rules, the choice is more complex than ever. Both FBA and FBM come with their own pros and cons based on your product size, order volume and business goals. This guide explains everything you need to know about FBA vs. FBM in 2025 including real cost comparisons, platform trends and expert tips to help you choose the best fulfillment method for your Amazon business this year.
What Is FBA
FBA, or Fulfillment by Amazon, means Amazon handles your storage shipping customer service and returns. You send your products to Amazon’s warehouse. When a customer places an order Amazon picks packs and ships it. They also manage refunds and support.
In 2025 Amazon made key changes. There is a new fee for inbound placement when shipments are split across warehouses. Long-term storage now costs more if your stock stays over 365 days. Restock limits are tighter and based on your past sales. Sellers must also track inventory health more closely using the restock report and storage volume metrics. FBA is still a strong choice for fast-moving products and for sellers who want Prime access without managing logistics.
What Is FBM
FBM or Fulfillment by Merchant means you store and ship products yourself. You handle packing shipping returns and customer support. You can do this from your own space or through a third-party logistics company.
After 2024 FBM saw more sellers using local 3PLs and warehouse partners to speed up delivery. Amazon now gives better support for sellers using Buy Shipping, which means using Amazon-approved carriers. This helps boost tracking and delivery accuracy. FBM gives full control over shipping and branding. It works best for larger items slow sellers or products that need custom handling.
