AI Models to Predict Restocks on Blinkit & Zepto

Case-Study-AI-Models-for-Predicting-Inventory-Restocks-on-Blinkit-&-Zepto

Overview

In the fast-paced world of quick commerce (Q-commerce), efficient inventory management is vital. Blinkit and Zepto, two leading players in India’s 10-minute grocery delivery ecosystem, face constant pressure to keep shelves stocked without overburdening storage. Actowiz Solutions deployed advanced AI models backed by real-time web scraping and historical pattern analysis to accurately forecast inventory restocks—ensuring zero missed sales and reduced wastage.

Challenges

Before partnering with Actowiz Solutions, both retailers faced:

Stockouts during high-demand periods, leading to revenue losses.
Excess inventory of non-moving SKUs due to inaccurate demand prediction.
Lag in vendor restock alerts, especially in pin code-based delivery zones.
Lack of SKU-level granularity in forecasting replenishment windows.
Manual coordination with warehouse ERP for perishable goods.

Objective

Predict restocking needs of high-frequency SKUs across cities.
Build a zone-wise AI model trained on pricing, order rate, and stock visibility.
Reduce product unavailability alerts on Blinkit and Zepto apps by 70%.
Improve vendor coordination based on near-term demand patterns.

Actowiz’s Approach

1. Real-Time Scraping Engine

Using Blinkit and Zepto's front-end interfaces, Actowiz set up a high-frequency scraping system that extracted:

Product availability by pin code
Stock status (e.g., "Only 2 Left", "Out of Stock")
Price changes and discounts
Reappearance timestamp of previously out-of-stock SKUs
Location-wise category rank

2. Historical Dataset Modeling

Actowiz gathered 6 months of SKU availability snapshots (every 30 minutes) for key cities like:

Delhi NCR
Mumbai
Bengaluru
Pune
Hyderabad

Sample data structure:

Date	City	SKU	In Stock	Quantity Tag	Reappeared After (hours)
2025-05-12	Mumbai	Amul Toned Milk 1L	No	-	4
2025-05-12	Mumbai	Amul Toned Milk 1L	Yes	"Only 3 left"	-

This data was used to train time-series models for each product + pin code combination.

3. Machine Learning Models Used

LSTM Neural Networks for SKU restock time prediction
Random Forest Classifiers for binary classification (restock likely/not likely in next 12 hours)
Gradient Boosted Trees for multi-variate regression on stockout duration
Bayesian Inference for estimating restocking frequency during promotions

4. Integrating External Signals

The AI models were enhanced with:

Blinkit & Zepto app promotions
Festival dates & traffic spikes (e.g., Diwali, Independence Day)
Weather data for fresh produce perishability
Vendor-wise replenishment cadence
