The Margin Diagnostic

​
What Is a Margin Diagnostic for Ecommerce?

A margin diagnostic is a focused analysis that identifies where a retail or e-commerce brand’s operations leak contribution margin — through over-discounting, misallocated media spend, underperforming customer segments, or channel-level margin erosion. DAS offers The Margin Diagnostic as a $5,000 entry-point engagement, credited toward a full retainer, that delivers a customer file analysis, margin leak identification, and 90-day recovery roadmap within two weeks. It is designed for brands generating $15M–$100M on Shopify Plus and Klaviyo.

​
What It Covers

1

Customer File Analysis

RFM segmentation and cohort LTV modeling on your Shopify and Klaviyo data to identify customer concentration and value distribution. We map the Champion segment, quantify what percentage of contribution margin they drive, and identify which acquisition channels and cohorts produced them.
2

Margin Leak Identification

Where contribution margin erodes — over-discounting applied to customers who would have purchased at full price, misallocated media spend concentrated in channels producing low-LTV cohorts, underperforming customer segments receiving investment disproportionate to their value, and channel-level losses hidden by blended gross margin reporting.

90-Day Recovery Roadmap

Prioritized actions ranked by margin impact. What to fix first, what to stop doing, and what to double down on. Written as a board-ready document that a new CMO can present to the executive team or a leadership team can act on immediately.

​
How It Works

Timeline: Two weeks from data access to delivery. What DAS needs: Read-only access to Shopify and Klaviyo. No proprietary tools, no additional software, no technical integration required. What you receive: A full customer file analysis, a margin leak identification document, and a 90-day recovery roadmap — delivered as a board-ready presentation. The $5,000 fee is credited in full toward a retainer engagement if you move forward. What it is not: A sales pitch. The Margin Diagnostic is designed to tell you the truth about your customer file, regardless of whether that truth leads to a DAS engagement. CMOs at brands generating $150K+ in monthly media spend treat $5K as attention and time investment, not financial risk.

​
Who It’s For

The Margin Diagnostic is designed for specific inflection points: New CMO — coming in and wanting a real baseline before committing to a strategy. The diagnostic produces the understanding that makes a 90-day plan credible rather than aspirational. Agency churn — burned by previous agencies and needing to understand why results are not compounding despite good creative and adequate media budget. The diagnostic identifies where the gap actually is. CAC crisis — cost of acquisition rising faster than LTV can absorb. The diagnostic identifies which channels are producing the problem and which are producing customers worth having. Flat email performance — high open rates, low revenue impact. The diagnostic maps the behavioral segmentation that makes email a margin driver rather than an activity metric. Scoreboard vs. P&L disconnect — marketing dashboards showing green while finance dashboards show something different. The diagnostic closes the gap between activity metrics and business outcomes.
The Margin Diagnostic is the entry point to every DAS engagement. Brands that skip it — and go straight to a retainer — invariably spend the first 60 days building the understanding the diagnostic would have provided on day one.
