The Challenge

This company ran on Excel spreadsheets and gut feelings. Every Monday, the operations manager spent 8+ hours pulling data from 7 different sources, copying into a master spreadsheet, building charts, and emailing PDFs to leadership.

By the time reports reached decision-makers, the data was already a week old. Problems that should have been caught Monday weren't visible until the following week. Opportunities slipped through the cracks.

Different departments had their own spreadsheets with conflicting numbers. Sales said they hit their quota; finance showed a different picture. No one trusted the data because everyone had their own version of the truth. Meetings devolved into arguments about whose spreadsheet was right.

The Solution

We built a custom admin dashboard that pulls data from every source automatically. No more copy-pasting between systems. No more conflicting spreadsheets. One dashboard, one source of truth.

The technical foundation is straightforward: a Next.js frontend for blazing-fast interactions, Supabase (PostgreSQL) as the central data warehouse, and background jobs that sync each data source on schedules appropriate to their update frequency—some hourly, some every 5 minutes for critical metrics.

Role-based access ensures everyone sees exactly what they need. Executives get the high-level KPI view. Sales managers drill down to individual rep performance. Operations tracks inventory and fulfillment. Same underlying data, customized views for each role.

We added automated alerts for KPIs that cross thresholds. Instead of waiting for the weekly report to discover a problem, the right person gets a Slack notification the moment something needs attention. Response time to issues dropped from 7+ days to under an hour.

Real-Time Data Sync

Automatic data ingestion from 7 sources. Some every 5 minutes, others hourly—tuned to each system's needs.

Role-Based Views

Executives, managers, and staff each see exactly what they need. No information overload.

Automated Alerts

Slack notifications when KPIs cross thresholds. Problems surfaced in real-time, not next week.
