Custom Field Calculator

A Google Chrome extension for calculating custom fields in Pipedrive CRM.

Overview

Enterprise sales teams using Pipedrive CRM were struggling with data integrity and manual calculation errors, costing hundreds of man-hours monthly. The Custom Field Calculator was conceived as a sophisticated middleware solution—a Chrome extension injecting a calculation engine directly into the CRM interface to automate complex arithmetic logic between custom data fields in real-time.

Technical Challenges

The most significant engineering challenge was achieving seamless, real-time synchronization with Pipedrive's dynamic DOM without introducing latency or stability issues. We had to reverse-engineer parts of the CRM's event loop to trigger calculations reliably upon field updates while ensuring the extension remaining lightweight and non-intrusive.

Outcome

The solution revolutionized the workflow for sales teams, saving an estimated 500+ hours of manual data entry per month for key clients and reducing calculation-related errors to near zero. It became an essential utility for high-volume sales operations, significantly improving data accuracy and forecasting reliability.
