3PL vs Fulfillment Center vs Warehouse vs Dropshipping vs FBA

3PL. Fulfillment center. Fulfillment company. Warehouse. Dropshipping. FBA.

People use these words like they mean the same thing, including the companies selling them. They don't. Some are the same service under a different name. Some are a completely different business model. Picking the wrong one usually doesn't fail on day one. It fails at your first busy season, when it's hardest to change.

Here's what each one actually is, how they compare, and how to tell which one you need.

The quick comparison

Now the detail.

3PL

A 3PL (third-party logistics provider) receives your inventory, stores it, picks and packs each order, ships it, and processes your returns. You own the product. They run the operation. Most charge for receiving, storage, pick and pack, packaging, and shipping, sometimes with a monthly minimum.

"Fulfillment company," "fulfillment service," "outsourced fulfillment," and "order fulfillment service" all mean the same thing. If you want the full explanation, start with what a 3PL is.

Fulfillment center

A fulfillment center is a building set up to ship individual orders fast: shelving and bins for small items, pack stations, carrier pickups every day. When people say "fulfillment center," they usually mean a 3PL's building.

The distinction matters in one place. A single 3PL might run five fulfillment centers in different regions. When you get a quote, ask which building your inventory will actually sit in, and tour that one, not the flagship.

Warehouse

"Warehouse" is the broadest term. Every fulfillment center is a warehouse, but plenty of warehouses aren't built to ship individual customer orders. Many are designed for pallets in and pallets out: storage, B2B freight, and cross-docking.

You'll also hear "public warehouse" or "contract warehousing." Both usually mean a warehouse that stores goods for multiple companies, typically by the pallet. Great if you need overflow space or a place to stage freight. Not great if you need 400 parcels out the door every afternoon.

When a provider calls itself a warehouse, ask directly whether they ship individual ecommerce orders, how many a day, and from which building.

Dropshipping

With dropshipping, you never touch the inventory. A customer buys from your store, you pass the order to your supplier, and the supplier ships it directly. You don't pay for storage, and you don't need a 3PL.

The tradeoff is control. You don't control stock levels, packaging, ship speed, or quality, and your margins are usually thinner. Most brands that start with dropshipping and find a winning product eventually buy inventory and move to a 3PL.

One confusing twist: in retail, "dropship" also means something else. A big retailer sells your product on its website, and you (or your 3PL) ship it straight to the retailer's customer. That's a 3PL service, not dropshipping in the ecommerce sense. On one RFQ we ran for a big-and-bulky brand, whether a provider's parcel rates covered those retailer dropship orders was one of the biggest open questions, because those orders carried real dollars.

Amazon FBA

FBA (Fulfillment by Amazon) means Amazon stores your inventory in its fulfillment centers and ships your Amazon orders, including customer service and returns for those orders. Your listings get Prime eligibility.

In that sense, Amazon acts as a 3PL for your Amazon business. The differences:

• FBA is built for Amazon orders. Amazon's Multi-Channel Fulfillment can ship orders from other channels using that same inventory, but your packaging and branding options are limited.
• Amazon sets the rules on prep, labeling, storage limits, and fees, and changes them on its own schedule.
• Amazon won't do custom kitting, branded unboxing, or retail EDI the way a 3PL will.

That's why most growing brands end up using both: FBA for Amazon, and a 3PL for their own site, wholesale, and prepping and replenishing inventory into Amazon. Some also ship Amazon orders themselves through Seller Fulfilled Prime, which needs a 3PL that can hit Amazon's delivery standards. Confirm that capability in writing. On one search we ran, a provider's Seller Fulfilled Prime support came up in conversation but was never confirmed, so we flagged it to the brand as an open question rather than assume it.

Other terms people confuse with a 3PL

Freight forwarder. Moves your freight from one place to another, usually internationally: booking ocean or air space, handling export paperwork. They get your container to the US. They don't store it or ship your orders.

Customs broker. Files your import entries and pays duties on your behalf. Often works alongside the forwarder.

Freight broker. Finds trucks for your freight. No warehouse involved.

FBA prep center. A warehouse that labels, bundles, and packs inventory to Amazon's requirements before sending it into FBA. Many 3PLs do this too.

4PL. A company that manages your logistics, including managing your 3PLs, as one accountable party. Mostly relevant for larger operations.

Shipping software. Tools that buy labels and print them for you. Useful if you ship in-house. Not a warehouse.

Which one do you actually need?

You haven't bought inventory yet and you're testing products. Dropshipping, or ship it yourself.

You ship fewer orders than a 3PL's minimum would make worthwhile. Keep it in-house, or look for a small local 3PL that wants small brands. When the providers in our network told us a premium jewelry brand was too small for them, that's exactly what I recommended.

You sell almost entirely on Amazon. FBA, plus a 3PL or prep center if you need to hold extra inventory or prep it before it goes in.

You sell on your own site, plus marketplaces or wholesale. A 3PL. If Amazon is a big channel, pick one that does FBA prep too.

You need somewhere to put pallets for a few months. A storage warehouse, not a fulfillment center.

You ship oversized, frozen, hazmat, alcohol, or high-value product. A specialist 3PL. Generalist fulfillment centers aren't built for it. See our pages on oversized, cold chain, hazmat, alcohol, and high-value fulfillment.

Whatever you pick, know your own requirements first. A brand once asked me to find them a warehouse for temperature-sensitive supplements, and when I asked whether they needed cold storage, the answer was "we'll figure that out later." That one question decides which of these options even applies.

Frequently asked questions

Is a fulfillment center the same as a 3PL? Usually, a fulfillment center is the building and the 3PL is the company that runs it. When someone says "fulfillment center," they generally mean a 3PL's facility.

Is a fulfillment company the same as a 3PL? Yes. "Fulfillment company" and "fulfillment service" are other names for an ecommerce 3PL.

Is Amazon FBA a 3PL? For your Amazon orders, it works like one. It's built mainly for Amazon, though, with Amazon's rules and fees, so most multichannel brands also use a 3PL.

Is dropshipping cheaper than a 3PL? You avoid storage and inventory costs, but you give up control over stock, packaging, and ship speed, and margins are usually thinner. It's a different business model, not a cheaper version of the same one.

What's the difference between a warehouse and a 3PL? A warehouse stores goods. A 3PL also ships your individual orders, handles returns, and connects to your store. Some warehouses do both. Many don't.
