Fulfillment Without FBA
Amazon's best product — and how to replace it
Complex migrationWhat 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.
What you lose
- Prime badge (the most visible trust signal on Amazon — affects conversion significantly)
- Amazon's logistics network (150+ fulfillment centers in the US)
- Hands-off fulfillment (FBA handles storage, packing, shipping, and returns)
- Amazon's negotiated shipping rates
Alternatives
- ShipBob — Largest independent 3PL for ecommerce. Good Shopify integration. Distributed network reduces shipping costs. Transparent pricing. Strong for direct-to-consumer.
- ShipMonk — Strong for subscription boxes and DTC brands. Flexible pricing model. Good for lower-volume sellers.
- Deliverr (now Shopify Fulfillment Network) — Shopify's built-in fulfillment network. If you're going full Shopify stack, worth evaluating. Fast 2-day delivery promise.
- ShipStation — Shipping software, not a 3PL. Connects your store to any carrier. You still need warehouse space, but it automates the shipping workflow. $9.99–$229/month.
- Self-fulfillment — For low-volume sellers, fulfilling from home or a small warehouse remains viable. ShipStation + your own storage. Works until you're shipping 50+ orders/day.
- Manufacturer / dropship direct — For some product categories, working with manufacturers who dropship directly eliminates the fulfillment problem entirely. Lower margins but zero inventory risk.
Migration steps
- Calculate your true FBA cost per unit (use Amazon's FBA fee calculator)
- Get quotes from ShipBob and ShipMonk for your top SKUs
- Compare total landed cost (product + fulfillment + shipping) for each option
- Plan inventory transition — you can run FBA and a 3PL simultaneously during transition
- Request inventory removal from FBA for SKUs you're moving (removal fees apply)
- Set up 3PL integration with your Shopify store
- Monitor shipping times closely — the Prime badge requires 2-day delivery; you'll lose it without FBA
- Consider Seller Fulfilled Prime (SFP) if you want to keep the Prime badge while leaving FBA (strict performance requirements)
