Context

With the new Multisite model (a single client with multiple installation sites), the manual Planning Calculation process—used to estimate additional costs by region and system size per site—became unsustainable.

Each calculation took ~15 minutes, and a single multisite client could require 30–50 sites per block, with multiple blocks per contract.

As operations scaled and the team shrank, the manual approach was no longer viable.

Action

During a temporary assignment due to bandwidth constraints, I was tasked with documenting 70 sites—implying a 2.5-day pause in my regular work.

Instead of following the manual process, I identified an opportunity to automate it and built a Retool app that:

  • Processes multiple calculations (sites/clients) per run using JavaScript

  • Extracts input data directly from the CRM using SQL

  • Executes calculations in bulk, replicating a Google Sheets calculator

  • Uploads results back to the CRM and logs document approvals via APIs

  • All in a single click

Result

+99% operational efficiency: processing time dropped from hours to seconds.

The solution enabled the Multisite model to scale without increasing team size and became a reference point for automating similar workflows.
