The biggest mistake most sellers make is treating FBA shipping and fulfillment costs as a passive, unavoidable expense. They see it as the cost of doing business, but they fail to manage it actively. This passivity eats away at profit margins that could otherwise be reinvested for growth, from marketing to product development.
One common pitfall is failing to account for total shipping costs when setting prices. It's easy to focus on just one part of the equation, like inbound freight, and forget the rest. But as Ken Wilson talks about on Firing The Man, you have to build all the costs into your margin calculations from the start. That means the fulfillment fee, storage fees, packaging, and the new inbound placement fees all need to be factored in. On The Smartest Amazon Seller, the hosts discuss how crazy Fulfillment By Amazon (Fba) Fees can get. If you don't account for all of them in your pricing, you aren't protecting your profit. You're just hoping there’s something left over, which is a terrible strategy.
Another mistake is blindly accepting Amazon's partnered carrier for your shipments without exploring alternatives. Amazon has negotiated excellent rates, as Jim Cockrum points out on an episode of Silent Sales Machine Radio. But that doesn't mean they are the cheapest option for every shipment every time. As Bradley Sutton and his guest discussed on the Serious Sellers Podcast, it pays to compare Amazon Global Logistics with other freight forwarders. Taking a few minutes to compare rates before you send a shipment can save you a surprising amount of money, which directly improves your profitability.
Finally, many sellers create their own cost problems through poor inventory planning. Shipping a huge amount of inventory to FBA at one time feels efficient, but it can lead to massive long-term storage fees that wipe out your margins. A guest on the Serious Sellers Podcast mentioned the importance of sending inventory in as early as possible and keeping it flowing to avoid fees. This is a crucial part of Supply Chain Optimization. Holding less inventory for shorter periods is almost always cheaper. Getting a better handle on your inventory forecasting and sending in smaller, more frequent shipments keeps your carrying costs low and your cash flow healthy.
When you stop seeing shipping as just a cost and start managing it as a strategic part of your business, you unlock the capital and confidence you need to grow.
