Amazon FBA vs. Third-Party Fulfillment: Which Is Right for Your Brand?

If you sell on Amazon, you have likely weighed Fulfillment by Amazon (FBA) against using an independent third-party logistics (3PL) provider. Both can ship your orders reliably, but they serve different strategies. Here is how they compare.

Fulfillment by Amazon (FBA)

With FBA, Amazon stores your inventory and fulfills orders through its vast network. The big advantages are Prime eligibility, which boosts conversion on Amazon, and Amazon handling customer service and returns for those orders.

The trade-offs: FBA fees can climb, especially long-term storage fees for slow-moving stock; branding is limited to Amazon packaging; and it is built around selling on Amazon, not your own store or other marketplaces.

Third-party (3PL) fulfillment

An independent 3PL fulfills orders across all of your channels, your website, Amazon (via Seller-Fulfilled Prime or FBM), and other marketplaces, from one pool of inventory. You gain custom branded packaging, more transparent pricing, and a partner invested in your whole business rather than one channel.

The trade-offs: you manage the relationship, and orders are not automatically Prime-badged unless you qualify for Seller-Fulfilled Prime.

Which should you choose?

Many successful brands use both: FBA for Amazon bestsellers to capture Prime shoppers, and a 3PL for their own store and multichannel orders. This hybrid model spreads risk and keeps inventory flexible.

If most of your growth is happening off Amazon, or you want consistent branding and multichannel control, a dedicated 3PL is usually the stronger foundation. Talk to ASL Ecommerce about a fulfillment strategy tailored to where your brand is headed.
