The most basic operational decision on Amazon is your fulfillment model: FBA (Fulfillment by Amazon stores and ships) or FBM (Fulfillment by Merchant, you ship)? FBA brings speed and Prime access but costs more; FBM gives control and margin but the operational burden is yours. The right choice depends on product type, volume and margin.
FBA wins if you want fast delivery, the Prime badge and a Buy Box edge, and prefer Amazon to handle storage/shipping.
FBM wins if you have large/heavy or low-volume products and prioritize cost and process control.

With FBA your products sit in Amazon's warehouses; Amazon packs, ships and handles returns and customer service. It brings the automatic Prime badge, fast delivery and a strong Buy Box edge — directly lifting conversion. In return there are storage and fulfillment fees, which add up on slow-moving or bulky products.
With FBM you ship orders yourself from your own warehouse (or via a 3PL). It gives full control over process and cost; for large/heavy, low-volume or high-margin products it helps avoid FBA fees. The downside is you must build speed and Prime yourself (Seller-Fulfilled Prime) and handle returns/customer service.
FBA trades margin for speed and ease; FBM demands effort for margin and control. Many mature sellers use a hybrid: FBA for fast-moving small items, FBM for bulky/heavy or slow items. Before deciding, calculate net profit per unit separately for FBA and FBM scenarios.
It depends on size, volume and margin; FBA usually wins for small-fast items, FBM for large-slow ones. Compare with our calculator.
Yes, via Seller-Fulfilled Prime, but it has strict delivery performance requirements.
Yes; the hybrid model is common — some SKUs can be FBA and others FBM by product type.
