Quick commerce (10–20 minute delivery model) has completely transformed retail operations.
But behind every fast delivery is a high-pressure store environment where performance is measured every minute.
For store managers and captains, success is not just about dispatching orders—it’s about meeting strict SLA (Service Level Agreement) metrics.

In this guide, we’ll break down the most important quick commerce KPIs:

📦 2. Fill Rate
📌 What is Fill Rate?
