Overview

Big Basket's bb daily service operates a high‑frequency subscription model where customer experience hinges on consistent delivery quality and reliable product handling. We partnered to examine the full journey—from order to doorstep—to quantify where friction occurs and how it affects churn.

Using hub‑level data across Ahmedabad, we analyzed complaints, refunds, and delivery windows, then connected those events to subscription changes. The result is a practical playbook that prioritizes operational fixes with the largest impact on retention.

Objectives

  • Identify top drivers of churn across product, subscription, and service experience.
  • Quantify refunds by reason and their financial impact.
  • Analyze delivery timeliness windows and complaint patterns.
  • Recommend actions to improve retention and operational efficiency.
