Amazon Seller Profit Tracker: How We Cut Costs by 12%

10 min read

Last month, SKU B07X lost 12% margin. We thought it was profitable until we dug into the numbers. Amazon’s $3.20 referral fee plus FBA fees ate into our bottom line. We weren’t tracking refunds either—another $2.5K/month gone. We switched fulfillment in March, but the real wake-up call came when we connected all our marketplaces to a profit tracker.

Why Amazon Sellers Lose Money Without a Profit Tracker

Amazon’s fees aren’t the only hidden costs. Refunds, ad spend, and shipping eat into margins. Last quarter, we ran negative profit on SKU B07X because we weren’t tracking refunds. A $2.5K/month hit we didn’t see coming. Multi marketplace order sync software helps, but you still need a profit tracker to see the full picture. We lost $12K/month until we fixed it.

How to Track Amazon Profit Accurately

Then there’s shipping. We switched fulfillment in March, but the real savings came when we connected all our marketplaces to a profit tracker. Now we see every cost.
