The opportunity

Your category has more room in it than your account is taking.

Before anything gets fixed, the audit answers a different question: what is this channel capable of producing? Share of category, margin per unit and catalog breadth all have a ceiling, and most brands are running well under all three.

01
Share

Rank you could hold

Where your ASINs sit against category demand, and what rank is realistically defensible with review velocity and content behind it.

02
Margin

Contribution you could keep

Contribution margin per SKU after fees, returns allowance and ad spend. The number that decides whether growth is worth having.

03
Breadth

Catalog you could be selling

Variations, bundles, sizes and adjacent lines that the category is already searching for and your catalog does not answer.

Then the arithmetic

The gap between that ceiling and today has a cause, and it is measurable.

It is rarely one decision. It is the weekly leakage below, compounding quietly against the plan.

Why it is not getting there

Nobody loses Amazon in a quarter. They leak it, weekly.

Amazon doesn't punish brands with one big failure. It charges rent — in wasted spend, suppressed listings, stranded units and unclaimed reimbursements — until the channel stops compounding.

01
Advertising

Search terms nobody audits

Zero-conversion terms keep spending because reviewing them is nobody's favourite Tuesday. Our workflows sweep them nightly and log every change.

02
Availability

Listings down while you sleep

A suppression at 2am is a lost day of rank. Remediation starts within hours, and the reinstatement is managed end to end.

03
Recovery

Money Amazon already owes you

Chargebacks, AVS disputes, shipment discrepancies and fee errors. Our founders built the reimbursement category — this is muscle memory.

What is your current ACoS costing your margin?

Move the sliders. This is arithmetic on your own numbers — the gap between what you spend today and what the same revenue costs at a tighter ACoS. No projections, no promises.

Ad-attributed share is the portion of revenue your campaigns are credited with. If you don't know it, leave it at 45% — the audit measures the real figure.

The 8-Cylinder System

From first look to live execution in seven days.

Onboarding is where most agency relationships lose their first quarter. Ours is a defined process with dates attached.

Hours 0–72

Audit

We identify the most important bottlenecks, risks and opportunities across listings, advertising, content and inventory.

Day 5

Roadmap

Findings become a prioritised plan with clear owners, dependencies and expected outcomes.

Day 7

Live

Operator named, pod assembled, workflows configured, reporting open. Execution begins against the roadmap.

Days 8–30

Build & test

Listing rebuilds, campaign restructure, first split tests. Every change versioned and visible.

Cadence

A week with your operator, inside a quarter with a plan.

The same five days, every week, so you always know where the account is. Above that sits the monthly and quarterly layer that decides what those weeks are for. Tabs advance on their own — click to hold one open.

Mon

Priorities set

The week opens on the scorecard. Your operator reads the weekend, ranks what moves the number, and the pod’s queue is rebuilt around it.

  • Weekend anomalies triaged
  • Roadmap items pulled forward
  • Blockers escalated with owners
Tue

Advertising

Campaign work lands early so there is data before Friday. Bids, placements and harvested terms, reviewed by a senior operator before anything ships.

  • Search-term harvest and negatives
  • Bid and placement adjustments
  • New structures staged for test
Wed

Catalog and content

Listing and content changes go live mid-week, versioned so a move in performance can be traced to the change that caused it.

  • Copy and image updates published
  • A+ and Brand Story revisions
  • Variation and attribute fixes
Thu

Health and recovery

The unglamorous engine. Cases, claims and reimbursements are worked to close rather than filed and forgotten.

  • Case follow-through and escalation
  • Chargeback and AVS disputes
  • Stranded and restock actions
Fri

Reporting

You get a written scorecard: what changed, what it did, and what happens next week. No dashboard archaeology required.

  • Weekly scorecard delivered
  • Split tests read and called
  • Next week proposed
Every month

Margin and forecast against plan

Contribution margin by SKU, forecast versus actual, and inventory cover read against the cash position. Where the number missed, the reason is named.

Every quarter

Roadmap re-prioritized

The annual plan is re-forecast, priorities are re-ranked against what the last quarter proved, and anything that stopped earning its place comes off the list.

Every quarter

Next quarter's growth plan

Launches, deal events, expansion and price moves, with the inventory and spend they require. You approve a plan rather than receive a recap.

Reporting & the Ops Tool

Reporting starts at contribution margin, not ACoS.

ACoS tells you what advertising cost. It does not tell you whether the channel made money. Reporting leads with contribution margin per SKU after fees, returns allowance and ad spend — then ACoS and ad-attributed revenue sit underneath it as the inputs they are.

Advertising, catalog, content, inventory and account health sit on one board, with every operator action logged against the item it touched. No monthly-deck reveal, no version of the truth you can’t check.

  • Live coverage across all five workstreams.
  • Every AI recommendation logged before it ships.
  • Change history you can trace to a performance move.

FAQ

No. Engin8 bills a retainer scoped to catalog size and cadence. Charging a percentage of ad spend pays an agency more when it spends more of your money, which is a misaligned incentive on a channel where efficiency is the goal.

A named senior marketplace operator owns your account and is responsible for priorities, decisions and outcomes. Execution runs through a dedicated delivery pod in Cebu working the same SOPs, with overlapping hours so handoff happens in real time rather than overnight batches.

AI handles monitoring, analysis and repetitive execution — overnight catalog audits, search-term hygiene, competitor tracking, restock signals and creative QA. Experienced operators still set priorities, approve decisions and remain accountable for execution. Every AI recommendation is logged before it ships.

Seven days from signed agreement to live execution. The sequence is a 72-hour audit, a five-day roadmap, then execution begins once access, scope and approvals are complete. Switching from another agency runs as a parallel onboarding so nothing goes dark.

Growth-stage and established DTC and CPG brands that need deeper marketplace expertise and execution capacity without building an internal team. Smaller catalogs are usually better served by our Foundation or Operations & health levels than by a full retainer.

Yes. Both, including hybrid accounts. Vendor coverage includes purchase orders, chargeback disputes, AVS support and the reconciliation work that recovers money Amazon already owes you.

Yes, and most brands do. TikTok Shop and creative run through the same team and the same reporting, so content produced for one channel is reused on the other rather than bought twice.
