Fulfillment Without FBA

Amazon's best product — and how to replace it

Complex migration

What it is

Fulfillment by Amazon (FBA) is Amazon's warehousing and shipping service. You send inventory to Amazon's fulfillment centers; they pick, pack, and ship. It's the logistics infrastructure that powers the Prime badge and two-day shipping. It's also the deepest operational dependency an Amazon seller has.

Honest assessment

FBA is genuinely excellent. The cost of replacing it is real — both in dollars and operational complexity. A seller moving from FBA to 3PL should expect 10–30% higher fulfillment costs and significantly more operational involvement. The tradeoff: you own the customer relationship, you control your inventory, and Amazon can't hold your stock hostage if your account gets suspended.

Migration steps

  1. Calculate your true FBA cost per unit (use Amazon's FBA fee calculator)
  2. Get quotes from ShipBob and ShipMonk for your top SKUs
  3. Compare total landed cost (product + fulfillment + shipping) for each option
  4. Plan inventory transition — you can run FBA and a 3PL simultaneously during transition
  5. Request inventory removal from FBA for SKUs you're moving (removal fees apply)
  6. Set up 3PL integration with your Shopify store
  7. Monitor shipping times closely — the Prime badge requires 2-day delivery; you'll lose it without FBA
  8. Consider Seller Fulfilled Prime (SFP) if you want to keep the Prime badge while leaving FBA (strict performance requirements)
