The E-commerce Engine: Profit-First Growth in a Closed-Loop World

The E-commerce Engine

Profit-First Growth in a Closed-Loop World

Winning the Buy Box is a Science. Scaling it is an Engine.

ROAS is a lie. If your advertising isn't fueled by inventory data and SKU-level profitability, you’re scaling your way to bankruptcy. On Amazon and Walmart, your ad is only as good as your warehouse.

The E-commerce Engine is the first book to bridge the gap between Marketing and Logistics. Kim Bowman breaks down the "Closed-Loop" advantage of Retail Media and shows you how to turn your ad spend into a permanent organic flywheel.

What’s Inside:

• The Flywheel Protocol: How to use paid velocity to "force" your way to the top of organic results.
• Beyond ROAS: A masterclass in TACOS, iROAS, and Contribution Margin—the metrics that actually matter in 2026.
• Agentic Commerce: How to optimize your store for the AI shopping assistants that will do 40% of the buying by 2027.

You’ll stop "running ads" and start Managing a System. This book is the difference between a struggling Shopify store and a marketplace powerhouse.
