The FBA Trap: Balancing FBA with a Smarter Distribution Model

Many brands are winning on Amazon but still losing ground on ecommerce.

Revenue is up. Orders are flowing. Marketplace dashboards look healthy. But when leadership looks at contribution margin, the numbers tell a different story.

That's the FBA trap.

Fulfillment by Amazon (FBA) can accelerate growth faster than almost any other channel. But when it becomes your only distribution strategy, the economy starts to tighten. What began as a growth engine quietly turns into a margin squeeze.

Many brands are winning on Amazon but quietly losing on margin

More than 80 percent of active Amazon sellers rely on FBA, and many report early profitability because of its reach and built-in logistics support.

For small, fast-moving products, FBA can be a smart growth engine. You ship inventory in bulk. Amazon handles storage, picking, packing, shipping, returns, and customer service. You gain speed without building your own network.

But Amazon FBA isn't a one-size-fits-all solution. While it offers significant advantages like Prime eligibility, simplified logistics, and built-in customer support, it also brings added fees, limited branding control, and over dependence on a distribution channel you don't control.

The Amazon Advantage

It's tough for any brand looking to expand ecommerce sales to ignore Amazon and the Amazon FBA program.

Amazon holds a commanding 40% of all US ecommerce sales. Its share remains far ahead of marketplace competitors like Walmart, which has a 6-7% share.
Amazon listings have a conversion rate of 10-15% on average - and up to 30% in some categories. This is far above the usual 1-3 % conversion rate of most other ecommerce sites.
Prime listings convert at an even higher rate, over 75%. Products enrolled in FBA are automatically included in the Prime program, giving your product access to millions of Prime members.

For brands new to ecommerce, FBA offers a quick and easy path to nationwide fulfillment with little investment or overhead. But for many brands, top management's concern is no longer "how can we expand into ecommerce" but "when are we going to start making money on ecommerce". And if FBA is your only distribution strategy, that will be a tough question to answer.

The Downsides of FBA

Amazon is expensive and FBA fees stack up.

You pay referral fees. Fulfillment fees based on size and weight. Monthly storage. Peak season surcharges. Long-term storage penalties. Inbound placement costs.

Sellers frequently underestimate how much these layered charges affect profitability, but it's not unusual for FBA fees to consume 40-55% of revenue.

Recent fee adjustments have added more pressure, especially for small and mid-sized operators. Individually, the fees may seem manageable. Together, they compress contribution margin. Brands chase top-line growth while bottom-line performance gets thinner. https://builtin.com/articles/amazon-fba-fees

If your entire fulfillment model runs through FBA, you have little leverage when costs change.

But fulfillment expense isn't the only issue working with FBA:

Amazon enforces restock limits and performance standards that can cap how much inventory you're allowed to send in. That means growth is partially controlled by platform rules - which are known to change suddenly and often with little notice.
FBA controls the shipping experience. The box is Amazon-branded. Communication flows through Amazon. Opportunities for branding or encouraging repeat purchases with shipments are few. Customer data access is limited. That makes it harder to build loyalty outside the marketplace. You can drive sales, but you may struggle to build long-term brand equity.
Not all products work well with FBA. Small, light, durable products that are easy to ship; high volume; and have high enough margins to support hefty FBA fees work well. Fragile, heavy, bulky items; slower-moving products; and products that need special handling may result in high fees and shipping costs.
You're competing inside someone else's system. When Amazon owns the customer touchpoint, pricing pressure increases. Sponsored ads become mandatory. Visibility depends on algorithm performance.

Where Walmart Fulfillment Services Fits

Walmart Fulfillment Services, or WFS, plays a similar role inside Walmart's marketplace.

It offers storage, pick, pack, and two-day shipping. It can improve listing visibility and conversion. For brands expanding beyond Amazon, WFS provides access to a different customer base and diversifies marketplace exposure.

But structurally, it works like FBA.

Inventory goes into Walmart's network. Fees apply. Platform rules govern performance. Customer relationships remain within Walmart's ecosystem.

WFS makes sense as a growth lever outside of Amazon. It should not become the backbone of your distribution strategy either.

If you replace FBA dependence with WFS dependence, you have not really diversified. You have just duplicated the model on a second platform.

The Smarter Approach: Layered Fulfillment

Industry experts increasingly recommend hybrid fulfillment strategies.

That means using:

FBA for high-velocity SKUs that benefit from Prime
WFS to capture Walmart marketplace demand
Merchant-fulfilled or 3PL models to fulfill products that aren't suitable for FBA or WFS

But there is another layer that many brands overlook.

The Distribution Channel as Infrastructure

Many brands leverage regional distributors to stock and service retail, small wholesale, and reseller accounts.

Regional distributors already operate multi-node warehouse networks. They already stock inventory. They already sit close to end online shoppers. And being close to customers cuts delivery time, distance, and expense.

The question isn’t whether to use FBA. It’s how much of your business should depend on it.

With shared inventory visibility and modern order routing, those networks can function as distributed ecommerce fulfillment engines.

The missing piece is connectivity.

Regional distributors already have the inventory and physical footprint. What they lack is shared, real-time inventory visibility and coordinated order routing across their locations. What brands miss is a way to integrate their multiple independent regional distributors into a single, coordinated, nationwide fulfillment network.

That is where The Distribution Network (TDN) fits in. TDN connects independent distributors into a unified fulfillment layer, allowing brands to see available inventory across distributors and distributor locations, and then intelligently route orders to the best - lowest cost - fulfillment option. The goal is not to replace FBA or WFS, but to make them part of a broader, more flexible system.

Instead of pushing all units into FBA or WFS, brands can:

Position inventory across regional distribution centers
Fulfill direct-to-consumer orders through brand-owned channels such as a Shopify store from the closest node
Support other online retailers with drop shipping programs
Replenish traditional retail customers from the same inventory pool

TDN protects margin because you're not paying for marketplace storage on every unit. It cuts shipping cost by using inventory already close to customers. It protects customer relationships when orders flow through your own ecommerce fulfillment channel. FBA and WFS then become tactical tools, not strategic dependencies

3PLs have their place. But they can be expensive, slow to onboard, and resource-heavy to manage. Leveraging regional distributors uses inventory already in place, without tying up additional working capital across multiple 3PL warehouses. It also strengthens your existing retail network by making distributors part of your ecommerce growth instead of competing with it.

Rent vs Build: What's Your Strategy?

FBA, WFS, and 3PL models have something in common. You are renting a distribution channel.

That rental model has its place. It buys speed. It buys access. It lowers the barrier to entry. For certain products and certain stages of growth, it makes perfect sense.

But rental infrastructure comes with ongoing fees, shifting rules, and limited influence. You operate inside someone else's economics.

The alternative is not to abandon marketplace fulfillment. It is to balance it with the infrastructure you build alongside long-time partners.

With The Distribution Network, brands are not placing inventory into a closed system. They are activating inventory already positioned across their regional distributors. They are strengthening the distributor relationships that already support their retail business. They are expanding ecommerce without sidelining the partners who helped build the brand in the first place.

One model rents capacity as needed.

The other builds capability, relationships, and long-term ecommerce profitability.
