Three supply chain mistakes that cost Amazon sellers in Q4

Amazon sellers heading into November without tightening their supply chain are taking a serious gamble with their profits, logistics specialists warn.

The three recurring mistakes: sending too much inventory too early and getting hit with Amazon's long-term storage rates; shipping too little too late and stocking out right before Black Friday; and relying on Amazon Warehousing and Distribution or a third-party logistics provider without accounting for the hidden fees and delays baked into their processes.

A new cheat sheet titled around seven supply chain myths lays out what actually causes delays, excess charges and missed inventory cutoffs this season, and how experienced operators are handling them differently.

The advice comes from a fulfillment network founded by former sellers that has spent more than a decade moving FBA freight, and its core message is urgency: trucking and warehouse costs climb every day sellers wait to lock in their fourth-quarter logistics.
