Nearly Doubling Gross Margin While Growing Revenue
A high-volume reseller was doing $1.2M a month but blended gross margin sat at a dangerous 6%. We rebuilt the catalog around real per-SKU economics and lifted margin to 11%.
// The Starting Point
Big Top Line, Dangerously Thin Margin
This seller was doing $1.2M a month, which looks great until you see what was left after costs. He ran a classic high-volume wholesale model: buy anything profitable and fast-moving he could get and push volume.
The problem was that blended gross margin (Amazon payout minus COGS) sat around 6%. On the working capital tied up in 1,560 SKUs and a heavy inventory position, that's razor-thin. One bad season or one fee increase and the math stops working.
Underneath the top line, money was leaking in places he had no visibility into.
// The Diagnosis
Money Leaking in Invisible Places
We analyzed the catalog and identified exactly where the 6% margin was bleeding out.
No per-SKU economics
Price, velocity, and lead time were never modeled together. A product selling 200/mo at 10% is worth more than one selling 350/mo at 5% — but the catalog treated them the same.
Return-rate blindness
Footwear and apparel carry far higher return rates, quietly eroding the real margin on exactly the SKUs he leaned on hardest.
Restocking by feel
Every vendor and brand had a different lead time. Without mapping it against sell-through, he overstocked some items and sold out of others.
Storage-fee bleed
Slow ASINs racked up LTSF and aged-inventory surcharges; the winners he under-ordered triggered low-inventory-level fees.
No visibility by brand
He couldn't see which brands actually made money. Decisions were made on gut feel because the data didn't exist in one place.
// The Strategy
Building a System to See the Truth
We didn't cut blindly. We built the system to see the truth at SKU and brand level, then acted on it.
Granular SKU economics
We modeled every SKU on price, velocity, and lead time. We factored in the real return rate to establish a minimum bearable gross-margin floor of ~12% per SKU.
A custom brand-level dashboard
We built a custom dashboard showing performance by brand — price, velocity, lead time, and margin in one view.
Reorder logic by lead time & velocity
With lead times mapped per vendor and demand mapped per ASIN, we set reorder thresholds to ensure capital flowed to the right products.
Storage-fee & overstock triage
We quantified what each ASIN cost in LTSF and aged-inventory surcharge, then sorted every overstock SKU into structured plays (sell at loss to clear, hold, run PPC, or remove).
Catalog rationalization
The data told us what to keep, double down on, and let go. We cut the dead weight and concentrated capital on proven SKUs, taking the catalog from 1,560 to 970.
// The Results
More Revenue, Better Margins, Smaller Catalog
Nearly doubled in about six months by enforcing per-SKU economics.
Cut 38% of the catalog — the part that was noise.
Revenue grew despite the smaller catalog.
Long-term storage fees eliminated through structured triage.

Why These Metrics Matter To Growth
Revenue without margin is just expensive volume. A $1.2M month at 6% gross is a business one bad quarter from trouble; at 11% it's a business that compounds.
The number that proves the thesis is the catalog cut. We removed 38% of his SKUs and revenue still went up. You can't optimize what you can't see.

Detailed Breakdown
| CATEGORY | SKUs | SHARE | ACTION | OUTCOME |
|---|---|---|---|---|
| Scaled winners | ~194 | 20% | Double down — increase inventory & ad spend | Revenue up on fewer, better SKUs |
| Stable performers | ~407 | 42% | Keep as-is — low maintenance | Steady profitable volume |
| Dead weight | ~369 | 38% | Cut / liquidate | $4,800 in storage fees cleared |
Is a thin margin hiding inside a healthy top line?
If you're moving real volume but the margin doesn't reflect it, the problem is usually buried at the SKU level. Let us audit your catalog.
