Key dashboard metrics to start with

Summary

Stephen Brown, COO at LedgerGurus and host of the Ecommerce Finance Podcast, sits down with Stacy Walker, Director of Growth at LedgerGurus. They break down the four margins every ecommerce brand should be tracking and why most 7- and 8-figure sellers only understand one of them. The conversation focuses on why founders feel profitable but still struggle with cash and confidence in their numbers.

This episode explains gross margin, contribution margin, net operating margin, and net profit margin in plain language. Stephen and Stacy walk through what each margin actually tells you, where brands get them wrong, and how bad data hides real problems. Listeners walk away knowing which margin points to pricing issues, ad efficiency problems, or bloated overhead.

Key Takeaways

• Gross margin isolates product and inventory costs, so you can see pricing and supply chain pressure early.

• Bad inventory data makes gross margin look fine, while profit quietly erodes.

• Contribution margin shows what is left after selling costs and determines how much room you have to operate.

• Low contribution margin leaves no buffer for payroll, software, or growth mistakes.

• Advertising efficiency is often the biggest driver of contribution margin swings.

• Net operating margin reveals whether overhead is sustainable as the business grows.

• Payroll is usually the largest hidden drain on operating margin.

• Net profit margin can hide problems when debt, taxes, or owner expenses are mixed into operations.
