Why Profitable-Looking Sales Don't Always Mean a Profitable Business
Where Margin Actually Leaks on Amazon
Rising FBA & Referral Fees
Amazon adjusts fulfillment and referral fees multiple times a year. If pricing hasn't kept pace, every unit sold is quietly less profitable than last year.
Ad Spend Without a Profit Ceiling
Campaigns optimized for sales or ACOS alone can spend past the point where a SKU is still making money.
Returns & Refunds
High-return categories can turn a healthy-looking margin into a loss once return shipping, refurbishment, and lost inventory are counted.
Storage & Aged Inventory Fees
Slow-moving SKUs rack up long-term storage fees that rarely show up until the quarterly bill arrives.
Pricing That Hasn't Caught Up With Costs
Supplier costs, freight, and fees move; retail prices often don't, until margin has already thinned out.
No SKU-Level Visibility
Blended, account-level profit hides which specific products are actually losing money.
How We Diagnose and Fix Profitability Issues
Full P&L Reconstruction
We rebuild your true profit and loss at the SKU level, including fees, ads, refunds, and storage, not just revenue minus COGS.
Margin Leak Identification
We flag the specific SKUs, fee categories, or campaigns responsible for the biggest drag on profit.
Pricing & Fee Review
We check current pricing against current Amazon fee schedules and recommend adjustments where margin has quietly eroded.
Ad Spend Realignment
We connect ad performance to actual product margin, not just ACOS, so spend supports profit instead of just top-line sales.
Ongoing Profitability Reporting
You get a recurring, plain-English view of profit by SKU so leaks get caught early next time.

Frequently Asked Questions
Why is my Amazon revenue growing but my profit isn't?
This usually comes down to costs growing faster than price: rising fees, higher ad spend per sale, more returns, or aged inventory charges. Revenue can climb while several of these costs quietly eat the difference.
How do I calculate true profit per SKU on Amazon?
Start with the sale price, subtract Amazon referral and fulfillment fees, cost of goods, allocated ad spend, storage fees, and an estimate for returns. Most sellers only track the first two or three of these, which is why the number looks better than reality.
Can high ad spend hurt profitability even with a good ACOS?
Yes. ACOS measures ad efficiency, not whether the sale was profitable once every cost is included. A campaign can hit its ACOS target and still fund sales that lose money after fees and returns.
How often should I review my Amazon P&L?
Monthly at minimum, and immediately after any Amazon fee update. Fee schedules change several times a year, and pricing that isn't revisited can lose margin without anyone noticing.
Do returns really make that much difference to profitability?
In categories like apparel, electronics accessories, and anything sized or fitted, yes. Return shipping, restocking, and the lost sale itself can turn an apparently profitable SKU into a net loss.
What's the fastest way to find out where I'm losing money?
A SKU-level P&L rebuild is the fastest path. It replaces blended, account-level numbers with a clear view of which specific products, campaigns, or fee categories are responsible for the gap.
