When FBA Wins
- Prime badge drives 2–3x more sales
- Scale — Amazon handles all fulfillment operations
- Multi-channel — Use FBA for non-Amazon orders too (MCF)
- Customer trust — Amazon's customer service handles issues
- Time savings — Focus on sourcing and marketing, not logistics
When FBM Wins
- Large/heavy products — FBA fees are excessive for oversized items
- Low-margin products — When FBA fees eat your profit
- Slow-moving products — Avoid long-term storage fees
- Custom/personalized products — Made-to-order items
- Local delivery — Products with regional demand
The Hybrid Approach
Many successful sellers use both FBA and FBM:
- FBA for fast-moving, standard-size products
- FBM for oversized, slow-moving, or custom items
- FBM as backup when FBA inventory runs out
Getting Inventory to FBA Efficiently
The key to FBA profitability is minimizing your inbound shipping costs. Working with Indray Inc for FTL and LTL shipments to Amazon FCs can significantly reduce your per-unit inbound cost compared to small parcel shipping.
