Ask most ecommerce owners how they want to grow profit, and the answer comes back in some version of the same word: Revenue. But revenue is actually the hardest lever to move, and it’s not the only one.

There are 5 key levers that drive profits in ecommerce: Revenue, Cost of Goods Sold (COGS), Platform Fees, Ad Spend, and Operating Expenses (OpEx).

Most sellers focus almost entirely on revenue — but the other four levers are often faster and easier to move. A 2% improvement in COGS or platform fees can have the same bottom-line impact as a 10–20% revenue increase.

Here’s what to focus on: Start with COGS. Renegotiate with suppliers, audit your product mix, and eliminate slow movers. Then look at platform fees — Amazon, Shopify, and payment processors all have room to optimize. Next, audit ad spend for efficiency, not just volume. Finally, review OpEx for subscriptions, tools, and overhead you’ve outgrown.

Revenue matters — but it’s the last lever to pull, not the first.
