Fulfillment by Merchant - sellers handle their own fulfillment for marketplace orders.

Why It Matters

FBM gives you control over fulfillment, packaging, and customer experience—important for brand-building. It avoids FBA's fees and restrictions. However, you lose Prime badge (usually), which significantly impacts Amazon conversion. FBM works best for large/heavy items or when margins can't absorb FBA fees.

Practical Example

Scenario

A furniture brand evaluates FBA vs FBM for their oversized products.

Calculation

FBA fees for oversized: $45 per unit + storage. FBM cost: $22 per unit via 3PL. Product margin at $200 price: FBA leaves $28, FBM leaves $51

Result

For large items, FBM is 2x more profitable. The Prime badge matters less for considered furniture purchases where customers expect longer shipping.

Pro Tips

  • 1Offer competitive shipping speed with FBM—Seller Fulfilled Prime is possible if you qualify
  • 2FBM works well for: oversized items, very high value items, customized products
  • 3Track your seller metrics carefully—late shipments hurt your account
  • 4Consider FBM for new product tests before committing FBA inventory

Common Mistakes to Avoid

Using FBM for Prime-sensitive categories where conversion suffers too much
Poor shipping metrics that lead to account issues
Not offering fast-enough shipping options to remain competitive
