Amazon 3PL fulfillment for sellers
A 3PL for Amazon sellers stores your inventory, preps FBA units, and ships your FBM and multi-channel orders so you don’t run a warehouse yourself. Simpl is an Austin, Texas 3PL built for Amazon sellers: same-day FBM shipping and FBA prep from one warehouse, on flat-rate pricing starting at $7/order with a dedicated account manager.
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.

How Simpl compares to ShipBob and Red Stag
ShipBob, Red Stag, and Simpl are all 3PLs Amazon sellers consider, but they’re built for different sellers. The right fit depends on your product, your volume, and how much hands-on support you want.
Simpl
An Amazon-seller-focused 3PL that runs FBM fulfillment and FBA prep from one Austin warehouse, on flat $7/order pricing with a dedicated account manager. Best for growing Amazon sellers who want a single stock pool, hands-on support, and predictable per-order cost.
ShipBob
A distributed fulfillment network that spreads your inventory across warehouses nationwide, run through self-serve software. Best for higher-volume sellers who want multi-node distribution and a software-first workflow over a named account contact.
Red Stag
A 3PL built for heavy, bulky, and high-value products, with accuracy and shrinkage guarantees. Best for oversized or high-ticket SKUs where breakage and shrink are the main risks, rather than light, fast-moving Amazon inventory.
Amazon 3PL pricing
Starts at $7/order.
Simpl’s fulfillment starts at $7/order, which covers the pick, the packing, and the postage. There’s a $750/month minimum, billed pay-the-difference: if a month’s order billing comes in under $750, you’re charged only the gap.
Storage is billed by the space you use (small bin, large bin, shelf, or pallet), not by cubic foot. FBA prep is priced separately.
Amazon 3PL FAQs
- What is the best 3PL for Amazon sellers?
- The best 3PL for Amazon sellers is one that handles both FBM order fulfillment and FBA prep from a single inventory pool, on pricing you can predict as you scale. Simpl does this from one Austin, Texas warehouse at a flat $7/order with a dedicated account manager, which fits growing sellers who want hands-on support. ShipBob suits higher-volume sellers who want a distributed, software-first network, and Red Stag suits heavy, bulky, or high-value SKUs. Match the 3PL to your product mix, volume, and how much support you want.
- 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.
