Weekend Demand Spike Report – Snacks & Drinks on Instamart

Overview

Weekends are the highest-traffic period for hyperlocal platforms like Swiggy Instamart, especially for snacks and beverages. Friday evenings and Saturdays see a huge surge in:

• Chips and salty snacks
• Cola and soft drinks
• Chocolates and biscuits
• Juices and energy drinks
• Ready-to-eat munchies

A leading FMCG conglomerate asked Actowiz Solutions to investigate:

"How do weekends change demand, pricing, and stock behavior on Instamart?"

This case study covers a deep data analysis of Friday–Saturday demand spikes, weekend OOS patterns, and pricing behavior across eight major Indian cities.

Actowiz Solutions collected the data using real-time crawlers that tracked Instamart every 10–15 minutes during weekend peak hours.

Client Challenge

The brand faced several issues during weekends:

• High stock-outs on fast-moving beverage SKUs

Juices, cola, energy drinks, and mixers regularly went OOS.

• Lost sales during Friday evenings

Key high-value packs were disappearing quickly.

• Competitor brands dominating visibility

When the client's products went OOS, rivals took the buy-box.

• Weekend price surges impacted consumer behaviour

Some SKUs saw increased prices due to high demand.

• No visibility into city-wise weekend patterns

Mumbai behaved differently from Bengaluru and Chennai.

• Unable to predict which SKUs would spike next weekend

Actowiz Solutions built a full weekend intelligence framework to track all parameters in real time.
