Choosing the Right Fulfillment Model for Amazon: FBA vs. FBM (2025 Deep Dive)
Introduction
Selecting your fulfillment strategy is one of the most important decisions you’ll make as an Amazon seller. Your choice affects costs, logistics, customer service quality, and your ability to win the Buy Box and Amazon Prime customers. In this detailed guide, you’ll learn how FBA and FBM work, what’s required, and how to pick the best strategy for your business.
Step 1: Understand the Basic Concepts
What is “Fulfillment” on Amazon?
- Fulfillment includes storing your inventory, packing orders, shipping products to customers, handling returns, and managing customer service queries.
- Amazon allows third-party sellers to choose between letting Amazon handle these logistics (FBA) or managing everything themselves (FBM).
Step 2: What is FBA (Fulfillment by Amazon)?
FBA means you send your products to Amazon’s warehouses. When an order comes in, Amazon picks, packs, ships, and handles customer service and returns for you.
How FBA Works:
- Create product listings and mark them as FBA.
- Prepare your product inventory following Amazon’s requirements (barcode labeling, packaging standards).
- Ship your items in bulk to Amazon’s fulfillment centers.
- Amazon stores your products until they sell.
- When a customer orders, Amazon packages and ships it, provides tracking info, and handles any issues or returns.
FBA Benefits:
- Prime badge eligibility for your products (more visibility and sales).
- Amazon handles all customer service and returns.
- Quicker delivery (customers can get 1- or 2-day shipping).
- Win the Buy Box more easily.
- Scalable: send large shipments, grow your sales, and expand globally.
FBA Drawbacks:
- Storage fees (monthly, plus extra for aged inventory).
- Per-item fulfillment fees.
- Risk of extra costs for oversized or slow-moving products.
- Less control over packaging and unboxing experience.
Step 3: What is FBM (Fulfillment by Merchant)?
With FBM, you—the seller—store your own products, pack orders, ship them to buyers, and handle returns and customer support.
How FBM Works:
- List your products as FBM on Amazon.
- Store inventory at your location or other warehouses.
- When a customer orders, you pack and ship products yourself.
- Provide tracking info and handle any questions, issues, or returns.
FBM Benefits:
- Full control over storage, packaging, and branding.
- Flexible shipping options—use your own rates, couriers, and special wrapping.
- Often more cost-effective for low-volume/oversized or complex products.
- No FBA fees, only pay Amazon’s referral (sales) fee.
FBM Drawbacks:
- Not automatically Prime-eligible (fewer buyers see your listings).
- More work—packing, shipping, customer messages, and handling returns.
- Must ensure fast, reliable shipping or risk account penalties.
Step 4: Head-to-Head Comparison Table
| Feature | FBA (Fulfillment by Amazon) | FBM (Fulfillment by Merchant) |
|---|---|---|
| Inventory Storage | Amazon warehouses | Your location/warehouse |
| Order Packing/Shipping | Amazon handles all | You/your team handle all |
| Prime Eligibility | Yes, automatic (Prime badge) | No (unless you qualify for SFP) |
| Buy Box Advantage | Easier | Harder |
| Customer Service | Amazon handles | You handle |
| Returns Management | Amazon handles | You handle |
| Costs | FBA fees (storage, fulfillment) | Your operating/shipping costs |
| Branding/Packaging | Limited customization | Full control |
| Best For | Fast-moving, small-to-medium products | Custom, oversized, slow-moving products |
| Scaling | Easier, less manual work | Limited unless you expand infrastructure |
Step 5: Fee Structure Examples
FBA Fees:
- Fulfillment fee per unit (e.g., $3.00 for standard size item)
- Storage fee (monthly, per cubic foot)
- Optional fees: long-term storage, removal order, returns processing
FBM Fees:
- No FBA fees
- You pay Amazon’s referral commission on each sale (typically 8%–15%)
- All shipping, storage, packaging, and staff costs managed by you
Example:
If you sell 100 units/month of a $30 product
- FBA: Fulfillment fees ($3 × 100 = $300), storage ($25), referral fees ($450)
- FBM: Only referral fees ($450), your own shipping/packing costs (~$150 depending on deals)
Step 6: Making Your Decision—How to Choose
- Go FBA if: You want to scale, don’t want to handle shipping, and want Prime customers.
- Go FBM if: You sell specialty, oversized, slow-moving, or custom products and value brand control.
- Hybrid: Many sellers use both—FBA for bestsellers, FBM for niche or custom items.
Step 7: Real-Life Example
Fatimah sells kids’ eco lunchboxes. Her mass-produced boxes go FBA for Prime reach. Her hand-painted custom orders go FBM—she packs and ships them with personal messages. This way, she gets higher sales volume and strong customer reviews!
Step 8: Getting Started with Your Chosen Model
- For FBA:
- Study Amazon’s FBA prep requirements (barcode, packing)
- Use Amazon’s shipment planner to send inventory to the right warehouse
- Monitor the “inventory health” dashboard
- For FBM:
- Set up order tracking and notification systems
- Choose reliable couriers or shipping software
- Create clear policies for returns, handling, and customer messages
