I. Core Definitions of FBA and FBM
- FBA (Fulfillment by Amazon)
FBA, also known as “Fulfillment by Amazon,” is an integrated warehousing and delivery service provided by the Amazon platform for sellers. Sellers must ship goods in bulk to Amazon’s global warehouses (FBA warehouses) in advance. Once a customer places an order, Amazon is fully responsible for picking, packing, and delivering the goods, as well as handling returns, exchanges, and customer inquiries.
- FBM (Fulfillment by Merchant)
FBM, also known as “Fulfillment by Merchant,” means the seller is solely responsible for the entire order fulfillment process. From storing goods in their own warehouses or third-party non-Amazon warehouses, to picking and packing goods after a customer places an order, liaising with logistics providers (such as international express and dedicated logistics) for delivery, and handling customer logistics inquiries, returns, and exchanges, all operations are coordinated and executed by the seller. Amazon merely acts as a trading platform, providing information display and order generation services.
II. Core Differences Between FBA and FBM
- Warehousing and Fulfillment
The core of FBA is “forward warehousing + platform fulfillment”: Sellers must prepare goods in advance at Amazon’s overseas warehouses. Amazon handles the storage and management of goods, as well as all fulfillment operations (picking, packaging, and shipping) after the order is placed, eliminating the need for sellers to directly engage with the logistics process.
FBM, on the other hand, involves “self-warehousing + seller fulfillment”: Sellers decide where to store goods (whether they own their own warehouses or local third-party warehouses). They must coordinate every step of order fulfillment (from warehouse to customer delivery), from sourcing packaging materials to selecting international logistics channels.
- Logistics Timeliness and Delivery Experience
Fulfillment by Amazon (FBA) offers a natural advantage in delivery time: Amazon’s overseas warehouses are often located in target markets. Consumers typically enjoy the same fast delivery services as local e-commerce platforms (such as Prime two-day delivery on the US site). Amazon also manages the entire delivery process, resulting in highly stable delivery times and a significantly improved customer experience.
Fulfillment by Amazon (FBM) delivery times vary significantly: using international express delivery (such as DHL and FedEx) can shorten delivery times to 3-7 days, but these costs are extremely high. Using dedicated logistics (such as air or sea delivery) can often result in delivery times of 15-30 days. Using postal parcels can even take up to 1-3 months. Furthermore, due to the numerous international logistics links and uncertainties surrounding customs clearance, delivery times are less stable, leading to long wait times for consumers and potentially causing dissatisfaction.
- Cost Structure and Controllability
The FBA cost structure is relatively fixed but complex: it primarily consists of “head-leg shipping” (the cost of shipping goods from China to Amazon’s overseas warehouses), “FBA storage fees” (a monthly fee for storing goods in Amazon warehouses, which may increase during peak seasons), “FBA handling fees” (labor and packaging costs for fulfillment, calculated by product category and weight), and “removal/disposal fees” (fees for removing goods from the warehouse or destroying them). These fees are standardized by Amazon and sellers can calculate them in advance. However, factors such as peak season storage fees and long-term storage fees may cause cost fluctuations.
FBM costs are controlled by sellers: the core costs are “domestic storage fees,” “order packaging costs,” and “international shipping costs,” with “customs clearance fees” added in some scenarios. Sellers can adjust costs by choosing different storage options (e.g., self-rented warehouses vs. shared warehouses) and logistics channels (e.g., postal vs. dedicated lines), providing greater flexibility. However, lower-cost channels often come with compromises in timeliness and service.
- Customer Service and After-Sales
FBA after-sales service is fully covered by Amazon: Consumers with issues such as delivery delays, package damage, and returns or exchanges can contact Amazon customer service directly. Amazon will then handle the return and exchange process, even reissuing or refunding the product in some cases. Sellers don’t have to deal with after-sales inquiries and disputes, saving significant customer service costs.
FBM after-sales service is entirely the responsibility of the seller: From customer inquiries like “When will the package arrive?” and “Why is customs clearance delayed?” to handling questions like “How do I claim for damaged goods?” and “How do I return an item I no longer want to buy?”, sellers must handle all of these issues independently. This requires not only a dedicated cross-border customer service team but also familiarity with the return and exchange policies and logistics claim procedures of different countries. Improper handling can easily lead to negative reviews and impact your store’s rating.
- Platform Traffic and Ranking Weight
FBA significantly boosts traffic: Amazon prioritizes traffic to FBA sellers, especially those offering Prime shipping. These sellers receive the “Prime” badge, resulting in higher search rankings and significantly higher click-through and conversion rates than FBM sellers. For new products, the FBA model can quickly accumulate sales and reviews, shortening the cold start period.
FBM sellers are inherently disadvantaged in terms of traffic: without the Prime badge, they typically rank low in search results, relying solely on organic traffic or paid advertising for exposure. Furthermore, due to poor delivery times and after-sales experience, consumers tend to prefer FBA products, resulting in generally low conversion rates for FBM products, making it extremely difficult for new products to achieve significant volume growth.
- Inventory and Capital Pressure
FBA carries significant inventory and capital pressure: sellers must stock their products in overseas warehouses in advance, which not only requires significant capital to purchase goods but also carries the risk of overstocking. If unsold goods become unavailable, sellers incur high long-term storage fees and may also suffer losses due to inability to clear inventory in a timely manner. FBM minimizes inventory pressure: Sellers can adopt a “ship on demand” model, even achieving “inventory-free” operations (e.g., drop shipping). This eliminates the need to tie up capital for inventory in advance, effectively reducing the risk of inventory overstock and providing more flexible capital turnover. It’s particularly suitable for sellers testing new products or those with limited financial resources.
III. Core Impact on Sellers
- Allocation of Operational Efforts
FBM significantly frees up sellers’ operational resources: Without having to deal with tedious tasks like warehousing, delivery, and after-sales service, sellers can focus on core business tasks like product selection, listing optimization, brand building, and market expansion. This is more conducive to the long-term scalability of their stores.
FBM, on the other hand, requires sellers to devote significant attention to the details of fulfillment: from connecting with logistics providers and tracking logistics information to handling after-sales disputes, every step must be handled personally. This can easily distract operational focus and make it difficult to support rapid store expansion.
- Capital and Risk Tolerance
FBA requires sellers to have higher financial strength and risk tolerance: upfront inventory preparation, first-leg transportation, and warehousing all require significant capital, and there are risks associated with unsold inventory and changes in Amazon warehouse policies (such as capacity restrictions and fee increases). Therefore, it is suitable for established sellers with ample funds and strong supply chain management capabilities.
FBM is more suitable for sellers with limited capital or a low risk appetite: there is no need to prepare inventory upfront, the capital threshold is low, and small-batch trial sales can be used to test market response. Even if the product is unpopular, the loss is minimal, making it an ideal starting model for new sellers or sellers in niche categories.
- Store Competitiveness and Long-Term Development
FBA is an “accelerator” for building a highly competitive store: leveraging Amazon’s logistics and service backing, it can quickly build consumer trust, accumulate high-quality reviews, and improve store ratings, thereby creating a positive cycle of “traffic-sales-ranking,” laying the foundation for branded operations and expansion into multiple categories.
FBM has significant competitive limitations: due to constraints such as timeliness, after-sales service, and traffic volume, it’s difficult to establish a differentiated advantage and often falls into the trap of “low-price competition.” In the long term, it’s difficult to increase store profit margins and market share. It’s more suitable as a “testing tool” or supplementary sales channel, rather than a core operating model.
- Product Selection and Market Compatibility
FBM has stricter product selection requirements: products with fast turnover, low slow-moving demand, and durable storage are required to avoid losses caused by overstocking. Furthermore, due to Amazon’s warehousing restrictions (such as high storage fees for large items), it is more suitable for small and medium-sized, high-demand, standardized products (such as 3C accessories and household goods).
FBM offers greater product selection flexibility: it can cover large items (such as furniture), low-demand niche products, and even fragile items (sellers can independently control packaging and delivery). It eliminates inventory pressures and allows for rapid response to niche market needs.
Summary
FBA and FBM aren’t mutually exclusive; rather, they’re two models tailored to sellers at different stages and with varying needs. FBA is a high-investment, high-return, and competitively competitive path to scale, suitable for established sellers pursuing traffic and long-term growth. FBM is an asset-light, low-risk, and highly flexible model for beginners, sellers in niche categories, or those with limited funds. For sellers, the key is to make a choice based on their financial resources, operational capabilities, product selection, and market objectives. Most established sellers adopt a hybrid model of “FBA-based, supplemented by FBM,” leveraging FBA to capture core traffic while using FBM to test new products or expand into specialized categories, achieving a balanced risk-return strategy.
