Calibray - IndiaPerformance Marketing / eCommerce AgencyData Engineering & Analytics Platform4 Resources4 Months

## What business challenges did we solve?

-   •
    
    **Managing 80+ Seller Accounts:** Calibray was serving over 80 Amazon Seller brands, each requiring periodic performance reports across ads, sales, inventory, and profitability metrics.
    
-   •
    
    **Manual Data Extraction:** Multiple team members were logging into Amazon Seller Central and Amazon Ads portals daily to manually download reports in CSV format.
    
-   •
    
    **Resource-Heavy Reporting Workflow:** Several analysts were involved in cleaning, merging, and transforming raw files before building charts in PowerPoint.
    
-   •
    
    **No Real-Time Visibility:** Clients relied on static monthly or weekly presentations and had no access to live performance data.
    
-   •
    
    **Scalability Risk:** As brand count increased, reporting workload grew linearly, creating operational bottlenecks and limiting agency growth.
    
-   •
    
    **Data Fragmentation:** Seller and Ads data existed in silos, preventing unified KPI calculations such as TACoS, blended ROAS, and contribution margin.
