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.

Summary

Stephen Brown, Founder of LedgerGurus, and Kelley Birrell, Marketing Manager at LedgerGurus, look back at the ecommerce predictions they made at the start of 2025. They review what actually happened across ecommerce growth, marketing costs, interest rates, inflation, and AI adoption. Each prediction is graded with real data and real-world operator context.

They also unpack the biggest curveballs of the year, including tariffs, de minimis rule changes, TikTok Shop growth, and the limits of new ad channels. Stephen shares where he underestimated risk, what surprised him about consumer spending, and why 2025 felt harder than expected for many brands. The episode helps sellers think more clearly about planning for 2026.

Takeaways

• Ecommerce returned to peak levels as a share of total retail sales.

• Marketing efficiency mattered more than chasing cheaper ads.

• Interest rate cuts did not meaningfully lower ecommerce lending costs.

• Inflation eased but continued to pressure consumer spending.

• Tariffs became the most disruptive force for ecommerce in 2025.

• De minimis rule changes reshaped dropshipping economics fast.
