What is Amazon Order Fulfillment?
Order fulfillment is the end-to-end process of receiving, processing, packing, shipping, and delivering a customer’s order. On Amazon, fulfillment also covers handling returns and refunds.
Amazon sellers can choose between:
- FBA (Fulfilled by Amazon): Amazon stores, packs, ships, and handles customer service for your products.
- FBM (Fulfilled by Merchant): You, the seller, handle storage, packing, shipping, and support.
- MCF (Multi-Channel Fulfillment): Use Amazon’s network to fulfill orders from other platforms like Shopify or eBay.
Step-by-Step Process of Amazon Order Fulfillment
1: Customer Places an Order
- A buyer places an order on Amazon.
- The system confirms product availability and sends order details to either Amazon (FBA) or the seller (FBM).
2: Payment Processing & Verification
- Amazon verifies payment and fraud checks.
- The order is marked “pending” until cleared, then “unshipped” for processing.
3: Inventory Check & Allocation
- FBA: Amazon’s fulfillment centers automatically allocate inventory.
- FBM: Seller checks their own warehouse/stock before confirming order.
4: Picking & Packing
- FBA: Amazon warehouse staff pick, pack, label, and prepare items.
- FBM: Seller picks the product, packs securely, labels with Amazon shipping ID, and ensures compliance with Amazon’s packaging requirements.
5: Shipping & Delivery
- FBA: Amazon selects carrier (Prime, standard shipping, etc.) and handles last-mile delivery.
- FBM: Seller must ship within the promised handling time and upload tracking.
6: Customer Receives the Order
- Order status is updated to “shipped” and then “delivered.”
- Buyers receive confirmation emails & tracking updates.
7: Returns & Refunds
- FBA: Amazon handles returns, inspections, and refunds per policy.
- FBM: Seller manages returns, inspects returned items, and issues refunds.
FBA vs FBM: Which Fulfillment Model Should You Choose?
| Feature | FBA (Fulfilled by Amazon) | FBM (Fulfilled by Merchant) |
|---|---|---|
| Storage | Amazon warehouses | Seller’s own storage |
| Shipping | Amazon handles delivery | Seller arranges shipping |
| Prime Eligibility | Yes | No (unless SFP) |
| Returns | Amazon handles | Seller handles |
