Amazon 3PL fulfillment for sellers

Amazon sellers use a 3PL to ship FBM orders, prep FBA inventory, and fulfill other sales channels without running a warehouse of their own. Simpl is that 3PL. We ship out of Austin, Texas, starting at $7/order.

What is an Amazon 3PL?

An Amazon 3PL is a third-party logistics provider that stores your inventory, preps it, and ships your orders for you. For Amazon sellers, that covers two jobs: shipping seller-fulfilled (FBM) orders straight to buyers, and prepping units to Amazon’s specs before they go into FBA.

Sellers use a 3PL to get around FBA storage limits, sell on more than one channel from a single inventory pool, and keep fulfillment costs predictable. You send one inbound shipment to the warehouse. From there, some units get prepped and forwarded to Amazon, and the rest ship as FBM or direct-to-consumer orders.

That’s one stock pool for every channel you sell on, at a fixed per-order price instead of Amazon’s size- and storage-tiered fees.

Amazon 3PL FAQs

What is an Amazon 3PL?
A 3PL (third-party logistics provider) for Amazon sellers is a company that stores your inventory, preps it, and ships your orders. It handles seller-fulfilled (FBM) orders directly to buyers and preps units to Amazon's specs for FBA. Sellers use one to ship faster, sell across more channels, and stay under Amazon's storage limits.
How does a 3PL help Amazon sellers?
A 3PL takes fulfillment off your plate. It ships your FBM orders with tracking, preps and forwards units to Amazon for FBA, and lets you sell on more than one channel from a single inventory pool. That means fewer FBA storage-limit problems and one accurate stock count across Amazon, Shopify, and your other channels.
What is the difference between Amazon FBA and a 3PL?
With FBA, Amazon stores and ships your inventory, but only for Amazon orders, and charges per-unit fees that rise with product size and storage time. With a 3PL, you keep your own inventory and can ship any channel, including Amazon FBM, on flat-rate pricing. Many sellers use both: FBA for Prime orders, a 3PL for everything else.
Can I use a 3PL for Amazon FBM orders?
Yes. FBM (Fulfilled by Merchant) means you ship your Amazon orders yourself instead of using FBA. Simpl handles FBM fulfillment for you: we pick, pack, and ship each Amazon order with a carrier and tracking, same-day when it's in before 12pm CT.
How much does Amazon 3PL fulfillment cost?
Simpl's fulfillment starts at $7/order, which covers the pick, packing, and postage. There's a $750/month minimum, billed pay-the-difference, so you're charged only the gap if a month comes in under $750. Storage is billed by the space you use (bin, shelf, or pallet), not by cubic foot. FBA prep is priced separately.
Does Simpl handle FBA prep and 3PL fulfillment from the same warehouse?
Yes. You send one inbound shipment to our Austin, Texas warehouse. From there, we prep and forward units to Amazon for FBA and ship your FBM and DTC orders from the same inventory. One inbound, two outputs, one stock count.
