Launching a business on Amazon feels a little like stepping onto a high-speed treadmill. The pace is relentless, the competition is merciless, and every decision you make about shipping and fulfillment can be the difference between sprinting ahead or faceplanting hard.
And right at the starting line, youâve got to choose between three heavy-hitting options: Fulfillment by Amazon (FBA), Seller Fulfilled Prime (SFP), and Fulfilled by Merchant (FBM). Each promises a slightly different path, but picking the right one depends on your products, your operations, and how much control you want to keep.
Before we dive into the nitty-gritty, hereâs the thing: Amazon isnât the only game in town. Many sellers work with an external ecommerce warehouse to manage inventory, or they plug into pick and pack fulfillment centers that streamline the process. Some even branch into Shopify fulfillment or run a hybrid model using subscription box fulfillment. The lines blur fast, but Amazonâs fulfillment methods remain the cornerstone for most sellers.
So letâs break down FBA vs SFP vs FBM like weâre sitting over coffee, laptop open, trying to figure out which button to actually click in Seller Central.
Think of these three as roommates who each have a different approach to cleaning the kitchen.
Letâs dig deeper.
With FBA, you send your products to Amazonâs network of warehouses. Amazon then takes over, handling storage, inventory management, order fulfillment, customer service, and even returns. Theyâre basically acting as your 3PL partner, though with a hefty layer of Amazon fees sprinkled in.
How to start with FBA:
I remember a business comrade in Los Angeles who swore by FBA when starting out. He loved the relief of not dealing with shipping headaches, but almost choked when he saw the storage bill during the holiday season. (Pro tip: those oversized yoga mats you thought would be a hit? Theyâll cost you more to store than your customer pays to buy them.)
SFP is Amazonâs way of saying: âSure, you can fulfill orders yourself, but donât screw it up.â You keep your products in your own ecommerce warehousing setup, and Amazon lets you slap the coveted Prime badge on your listings, if you pass their trial by fire.
The trial phase includes:
Pass those hoops, and you can handle fulfillment your way while still reaching Prime shoppers.
Some sellers outsource to an SFP-qualified pick and pack warehouse, while others build their own teams. Either way, youâve got to maintain Prime-level speed. Weekend delivery? Yep, thatâs on the table.
FBM is the most DIY route. You list your items, store them in your own warehouse (or your garage, if youâre scrappy), and fulfill each order yourself. You keep control, but you also shoulder everything: shipping, customer service, returns.
The obvious downside? You lose Prime eligibility. And letâs be honest, many shoppers wonât even glance at your listing if it doesnât come with that little blue checkmark of trust.
Still, FBM makes sense if youâve got specialized products, oversized goods, or custom packaging that FBA and SFP donât handle gracefully. For example, if youâre selling hand-stitched denim jackets, FBM lets you control every box, sticker, and handwritten thank-you note.
Hereâs the truth: thereâs no universal âbest.â Itâs all about trade-offs.
Quick note: you can mix and match. Sell some SKUs through FBA, others through FBM. Just not the same product in the same market at the same time.
Fulfillment costs arenât just fees on a page. They hit your margins like a surprise toll booth on a long road trip.
This is where working with a partner like ShipBots comes in. By outsourcing to a pick and pack fulfillment center or tapping into kitting and assembly services, sellers can lower per-unit costs while still offering fast, reliable delivery.
Hereâs the part Amazon doesnât highlight: their prep requirements are intense. Every unit needs barcodes, bubble wrap, proper cartons, the works. Mess it up, and Amazon rejects your shipment.
At ShipBots, we act as a buffer. You send inventory to us first, we handle labeling, prepping, and compliance with Amazonâs FBA guidelines, and then ship it on to their centers. Within 24â48 hours, your products are ready for sale.
Plus, our system isnât Amazon-exclusive. You can sync Shopify, subscription boxes, or even fashion fulfillment with the same workflows. That means one central hub, less chaos.
Choosing between FBA, SFP, and FBM feels like picking a lane in rush-hour traffic. Each has advantages, each has bottlenecks. The smart play is knowing where your products fit best and keeping your options open.
And if youâd rather avoid the treadmill of Amazon logistics altogether? Partner with a 3PL like ShipBots that knows the game inside out. Weâll prep, store, and ship while you focus on scaling.
Because honestly, wouldnât you rather spend your time growing sales than figuring out whether bubble wrap counts as âsuffocation hazard compliantâ?
