FBA vs FBM — Frequently Asked Questions
What is the main difference between FBA and FBM?
FBA (Fulfilment by Amazon) means Amazon stores, packs, and ships your products. FBM (Fulfilment by Merchant) means you handle warehousing and shipping yourself. FBA gives you Prime eligibility but adds fulfilment and storage fees.
Which is more profitable — FBA or FBM?
It depends on your product size, weight, sales velocity, and shipping costs. Lightweight, fast-selling products usually favour FBA. Heavy, slow-moving products often favour FBM to avoid high fulfilment and long-term storage fees.
What are typical Amazon FBA fees?
FBA fees include a referral fee (typically 15%), a fulfilment fee based on weight/size (starting ~$3.22 for small standard items), and monthly storage fees ($0.87/cubic ft from Jan–Sep, $2.40 Oct–Dec).
Can I use both FBA and FBM at the same time?
Yes — many sellers use FBA for their main inventory and FBM as a backup (called 'FBM ghost listing') during stockouts. This protects your ranking while your FBA shipment is in transit.
