In practice

Bottom line: as of October 2026, the Professional plan costs $39.99 a month plus selling fees, and FBA adds per-unit fulfillment and storage fees that Amazon sets by size, weight and storage time.

What is the difference between FBA and FBM?

According to Amazon's seller site, FBA outsources packing, shipping, customer service and returns. Your inventory sits in Amazon's network, and you pay per unit and per order.

What does each model cost?

The two Amazon pages we read do not publish a per-unit FBA fee table, so check Amazon's current schedule before deciding.

FBA enables fast, free Prime shipping and the Prime badge in search results. FBM sellers can apply for Seller Fulfilled Prime, which shows the badge on self-fulfilled listings.
