01 The Situation

A catalog that grew faster than the infrastructure behind it.

The brand entered 2022 with ~40 SKUs across the US, Canada, and UK. Top-line revenue looked healthy. Underneath, three structural problems were quietly compounding.

01

Profit blindness at the SKU level

Products were being advertised at a loss. COGS was missing from the margin math, so negative-contribution SKUs went undetected and kept receiving ad spend.

→ Missing COGS · spend misallocated
02

PPC built for a different brand

110 campaigns running for ~20 products at ~50% ACoS. The architecture was bolted-on, not designed — every new SKU added another seam.

→ ACoS ~50% · 110 campaigns / 20 products
03

Inventory run on instinct

The hero SKU represented 80% of revenue and routinely stocked out, while dead stock accumulated in FBA. Reactive reorders were eroding the rank that took years to build.

→ Hero SKU stockouts · dead stock in FBA
02 The Intervention

Four Moves. One Principle. A Brand Rebuilt Around Margin.

The approach was architectural before it was operational. Atomic One integrated COGS, FBA fees, and ad spend at SKU level so margin became real-time; from there, the AI agents took over the operational layer — PPC, inventory forecasting, and continuous catalog upgrades.

Foundation

SKU-level margin visibility

Integrated COGS, FBA fees, and ad spend per SKU. Margin became a real-time number — not a quarterly accounting exercise.

II
Ad layer

PPC rebuilt: spend follows margin

Campaign architecture consolidated. AI agents bid against contribution margin, not topline volume — one principle, applied portfolio-wide.

ACoS 50% → ≤35%
III
Inventory layer

Demand forecasting, not gut feel

A custom forecasting system replaced reactive reorders. Stockouts on the hero SKU eliminated during a 75% sales surge.

IV
Catalog layer

Continuous catalog upgrade

Audited, cleaned, and put on a continuous cycle. Attention shifted from defending old SKUs to identifying where demand was growing and competition wasn't.

Hero share 80% → 30%
03 The Results

Margin-First Reorientation, Compounded.

The impact became visible in year one and compounded each subsequent period. Net profit roughly tripled in three years — while the catalog diversified and the operational load decreased.

New Records
March all-time high

March 2026 becomes the most profitable single month on record. The compounding curve continues.

I'm not sitting there stressing about stockouts because the system is already flagging potential issues weeks in advance. My role has genuinely shifted from operational to strategic. I'm spending a lot more time asking "what's next?" instead of "what's on fire?"
