## The challenge

A multi-location service business ran its operations on a stack of spreadsheets, a
shared inbox, and manual copy-paste between tools. Leadership had no real-time
view of the pipeline, and month-end reporting took a senior team member hours of
error-prone work.

## What we built

A **custom CRM and reporting portal** that:

- Unified five disconnected data sources into one system
- Managed clients, jobs, and pipeline with role-based access
- Automated month-end reporting that used to be manual
- Gave leadership a live dashboard across all locations

## The approach

1. **Process mapping** with the operations team
2. **Data migration** and cleanup from spreadsheets and legacy tools
3. **Phased rollout** starting with the highest-pain workflow
4. **Training** so the team adopted it quickly
5. **Iteration** based on real usage

## Results

Reporting that used to take hours became a few minutes, data lived in one place,
and leadership finally had real-time visibility — without per-seat SaaS costs.
