FBA vs FBM — How to Choose the Right Model
FBA vs FBM (self-fulfillment) is the first major decision for new sellers. Each model has its own sweet spot — picking the wrong one leads you astray.
1. Definitions aligned
- FBA (Fulfillment by Amazon): You ship goods to Amazon warehouses; Amazon handles pick, pack, ship and returns. Amazon runs the warehouse + delivery integrated service.
- FBM (Fulfillment by Merchant): You hold goods in your own warehouse (in China or overseas); on each order, you arrange the carrier.
2. Core dimensions
| Dimension | FBA | FBM |
|---|---|---|
| Storage fees | USD 2-4/cu ft/month peak | Self-managed |
| Delivery speed | Prime, 2-day | Varies, 7-14 days |
| Cash-flow pressure | Heavy (pre-stock to Amazon) | Light (on-order) |
| Buy Box priority | High | Medium |
| Returns handling | Amazon (buyer-friendly) | You handle |
| Inventory risk | High (slow-mover storage fees) | Low (on-demand) |
| Best for | High-turnover / small standard SKUs | Bulky / custom / low-turnover |
3. Seller profiles
FBA winners:
- Single SKU daily sales ≥ 10 units
- Small size (< 50×50×50 cm), durable
- Buy Box drives revenue
- 3–6 months operating capital
FBM winners:
- Bulky, furniture, customized products
- Trial phase, uncertain demand forecast
- Cash-flow tight, prefer “ship-on-order”
- High return rate, need manual QA
4. Hybrid model — common optimum
FBA main warehouse + FBM supplement is the typical mid-scale seller strategy:
- Bestsellers → FBA: secure Buy Box
- Long-tail / bulky / custom → FBM: control inventory
- Pre-peak FBA overstock → convert to FBM: lower inventory pressure
5. AYC’s decision advice
- New, 1 SKU: FBM, run through the workflow first.
- 3-5 winners: FBA, lock profit on hero SKUs.
- Dozens of SKUs: Hybrid, overseas warehouse + FBA coexist.
