What business challenges did we solve?

  • Multi-Account Amazon Reporting: Calibray managed more than 80 Amazon seller brands across multiple marketplaces, with each account requiring recurring sales, inventory, traffic, advertising, and profitability reports.

  • Manual Seller Central and Ads Exports: Analysts repeatedly logged into Amazon Seller Central and the Amazon Ads console to download separate CSV reports for seller operations and advertising performance.

  • Fragmented SP-API and Advertising Data: Sales, traffic, inventory, campaign, keyword, and search-term data lived in disconnected reports, making it difficult to compare advertising spend with total marketplace revenue and stock availability.

  • Slow KPI Preparation: Team members spent approximately eight hours per brand during a monthly reporting cycle cleaning files, mapping products, calculating metrics, and preparing presentation charts.

  • Limited Client Visibility: Brands depended on static weekly or monthly presentations instead of a secure, self-service dashboard with consistently refreshed performance data.

  • Linear Scaling Costs: Every additional brand increased extraction, transformation, quality-checking, and presentation work, limiting the agency's ability to grow without adding reporting headcount.

Our technical approach and implemented solution

  • 1

    Amazon SP-API and Ads API Architecture: Designed a unified pipeline in which Amazon seller and advertising data flowed through scheduled ingestion jobs, validation and normalization services, a PostgreSQL data warehouse, a KPI computation engine, and a secure multi-tenant dashboard.

  • 2

    Rate-Limit-Aware Multi-Account Ingestion: Built Node.js ETL workflows to collect daily data from more than 80 Amazon seller accounts and advertising profiles while scheduling requests around API rate limits and asynchronous report availability.

  • 3

    Seller and Advertising Data Normalization: Standardized sales, traffic, inventory, campaign, keyword, search-term, and advertising performance records across brands and marketplaces, with shared dimensions for seller accounts, products, SKUs, ASINs, campaigns, and reporting dates.

  • 4

    Centralized Amazon Data Warehouse: Modeled normalized operational and advertising data in PostgreSQL so analysts could compare marketplace revenue, ad-attributed sales, spend, traffic, inventory health, and profitability from one governed source.

  • 5

    200+ KPI Computation Engine: Automated calculations for ACOS, TACoS, blended ROAS, contribution margin, inventory turnover, sales velocity, SKU-level profitability, campaign trends, and portfolio health.

  • 6

    Secure Multi-Tenant Analytics: Implemented brand-level data isolation and role-based access so every client could view only its authorized seller and advertising data while agency administrators retained centralized oversight.

  • 7

    Daily Refreshed Dashboards: Replaced static PowerPoint reporting with more than 80 interactive visualizations covering campaign performance, search terms, targeting, sales trends, inventory forecasts, and brand-level scorecards.

  • 8

    Automated Reporting Operations: Reduced repetitive CSV extraction, spreadsheet transformation, KPI calculation, and chart preparation, allowing analysts to spend more time interpreting performance and optimizing campaigns.
