Why did the store partner model fail in other quick commerce markets?

This partner model was actually tried by a few earlier startups but it ran into massive operational friction.

Beyond inventory mismatches speed is the biggest bottleneck a kirana owner has to manage walk in customers cash payments and chit-chat while dark store staff exist solely to pack orders in under 90 seconds. Plus, quick-commerce platforms make better margins when they buy bulk inventory directly from brands instead of splitting profits with a middleman shop.

Have you seen any local apps successfully blend both models in Delhi?
