Introduction

An accounting firm with 21 employees was losing over 70 hours per week on manual notifications — paper notes, individual message sending, and tax deadline tracking with no centralized system. Each missed deadline meant real risk of fines for their clients. This project eliminated that bottleneck with automation and real-time visibility.

Before and After

"Absurd time savings for each employee." — CEO


The Challenge

Each employee spent about 40 minutes daily on manual notes and message sending — totaling over 200 minutes per week per person. Multiplied by 21 employees, that was over 70 hours wasted weekly. Notifications were tracked on paper calendars, leading to frequent errors and risking tax penalties for missed deadlines.

Our Approach

The project team conducted interviews at the client's company to understand their processes. They designed a web-based platform using Node.js for the backend and vanilla JavaScript for a lightweight frontend, integrating with WhatsApp and Email via webhooks.
