Case Studies — Verified Account Results

Real Amazon accounts. Real numbers.
No fluff, just performance.

Six engagements, six different starting points — a fulfillment migration, a stalled ad account, a profit leak, a stalled revenue line. Here's exactly what changed, month over month, with the dashboards to prove it.

The Client

KXNG Cosmetics — from FBM to FBA without losing a beat

KXNG Cosmetics came to EcoMarix as an established Amazon seller shipping orders themselves through FBM (Fulfilled by Merchant). Growth had plateaued: shipping delays were affecting account health, and PPC spend was climbing faster than sales.

They needed a partner who could manage the operational move to FBA without disrupting live sales, while simultaneously rebuilding their advertising structure to bring ACoS under control.

The Engagement

Challenge, approach, and outcome

What KXNG was facing, what we changed, and where the account landed.

The Challenge

Manual FBM fulfillment was capping order volume and creating late-shipment risk. PPC campaigns were unstructured, driving spend without proportional sales — pushing ACoS higher every month.

Our Approach

We planned and executed the FBA migration alongside live operations, rebuilt the PPC campaign structure around real margins, and layered in negative-keyword harvesting and bid management.

The Result

The FBM-to-FBA transition happened without a hitch. ACoS improved significantly, and sales scaled consistently month over month with no disruption to account health.

How It Unfolded

A phased rollout, not a disruptive switch

★★★★★

"We've been working with EcoMarix for the past 4 months, and they've done an excellent job managing our account — ensuring a smooth transition from FBM to FBA without major issues. Their PPC expertise significantly improved our ACoS while scaling consistently month over month."

One Month, Same Budget

ACOS cut from 55.78% to 42.24% — without spending a dollar more

An Amazon account came to us with ad spend climbing and profitability shrinking. We didn't add budget — we fixed where it was going.

55.78% → 42.24%ACOS (April → May)
$9.6K → $12.9KSales (April → May)
$5.36K → $5.46KAd Spend — Nearly Flat
300 → 400Purchases (April → May)
Amazon PPC performance dashboard for April — 55.78% ACOS, $5,361.64 spend, $9,611.52 sales, 300 purchases

Before — April 2026

Amazon PPC performance dashboard for May — 42.24% ACOS, $5,455.69 spend, $12,917.16 sales, 400 purchases

After — May 2026

What we focused on

  • Eliminating wasted ad spend on non-converting search terms
  • Restructuring PPC campaigns around actual margin, not just visibility
  • Improving keyword targeting and match-type discipline
  • Scaling budget into search terms that were already proving profitable

9-Month Trajectory

Ordered Product Sales nearly doubled — from $124,581 to $231,012 a month

Over a 9-month engagement, one seller's monthly Ordered Product Sales climbed from $124,581 (August 2025) to $231,012 (April 2026) — driven by PPC optimization, listing improvements, B2B channel expansion, and cutting wasted ad spend.

Business Report — Month-Over-Month Growth

The growth wasn't accidental

It came down to a focused, repeatable strategy: PPC optimization to stop wasted spend, listing improvements to lift conversion, and B2B channel expansion to open a second demand stream on top of retail — all measurable, and all stacked on top of each other month after month.

Case Study 04 / Profit, Not Just Revenue

Same Account, Same Products

Net profit went from -12% to +208.8% in two months

Growing revenue is one skill. Growing net profit is another. This account was losing money in April — by the first 12 days of June, on the same products, net profit had turned around completely.

Month-Over-Month Net Profit Comparison

Where the money was leaking

We identified exactly where profit was being wasted — on the wrong keywords, inefficient ad spend, and listing gaps that were suppressing conversion — and fixed each one systematically instead of just pushing more budget at the account.

Case Study 05 / Full Account Takeover

6-Month Trend

From thin margins to £17,545 net profit in a single month

We took over full management of this account in mid-2024. Over the following six months, units sold, net profit, and overall account health climbed steadily — culminating in a January net profit of £17,545.44.

Units Sold, Ad Spend & Net Profit Since Takeover

What a full takeover looks like

Rather than optimizing one lever, we ran the account end-to-end — advertising, listings, inventory health, and margin tracking together — so growth in units sold translated directly into growth in net profit, not just top-line sales.

Case Study 06 / PPC ROI

One Month, Lower Spend, Higher Return

ROAS improved from 2.72 to 4.53 while cutting ad spend

By restructuring campaigns and scaling only what was already profitable, this account grew sales month-over-month while actually reducing what it spent on ads.

2.72 → 4.53ROAS (November → December)
$41.9K → $59.1KSales (November → December)
$15.3K → $13KAd Spend — Reduced
875 → 1,188Orders (November → December)
Amazon advertising performance for November — 875 orders, $15,376.84 spend, $41,828.92 sales, 2.72 ROAS

Before — November

Amazon advertising performance for December — 1,188 orders, $13,056.50 spend, $59,116.76 sales, 4.53 ROAS

After — December

Not a one-time spike

This improvement came from eliminating wasted spend, tighter audience and keyword targeting, and conversion-focused listing optimization — the same repeatable approach applied across every account we manage.
