$22,000 per month was invisible in the dashboard. We found it in 7 days.
The Background

A growing D2C brand with a ROAS problem nobody could see

A supplement brand selling direct through Shopify was spending $120,000 per month on Meta. The marketing team was reporting a ROAS of 4.2× — comfortably above target.

The numbers looked healthy. Revenue was growing. But margin was compressing quarter over quarter, and nobody could explain why.

What We Found

Three data gaps hiding $22,000 per month

1. Attribution gap — 38%

Meta's pixel lost approximately 30% of conversion signals after iOS 14.5. The reported 4.2× ROAS included conversions that never happened. Verified ROAS: 2.3×.

2. SKU profitability blindspot

The top-selling SKU had a 6% net margin after returns and fulfilment — well below the blended average.

3. Checkout funnel leak

Instagram Stories mobile had a 78% cart abandonment rate — accounting for $5,000 per month in lost revenue.

We thought our Meta was working. MornningStar.ai showed us exactly where it wasn't — and the fix took one afternoon.

Campaign restructure: Moved budget towards Conversions API-verified audiences with confirmed purchase signals.
