Automating Warehouse Management with Python and MongoDB

Managing a warehouse efficiently requires real-time inventory tracking, automated stock updates, and data-driven decision-making. Python, MongoDB, and Pandas can streamline operations by automating stock management, reducing errors, and optimizing warehouse space.

Lillqvist Strat provides automation solutions that increase accuracy and improve warehouse efficiency.


1. Warehouse Needs

An automated warehouse management system should:

  • Track inventory in real time using MongoDB.
  • Automate stock level updates and reorder alerts.
  • Use Pandas to analyze stock trends and improve efficiency.
  • Provide real-time dashboards for warehouse managers.

2. MongoDB Inventory Schema

We use MongoDB to store warehouse inventory and track stock levels dynamically.

Setting Up the Database

from pymongo import MongoClient

client = MongoClient("mongodb://localhost:27017/")
db = client["warehouse_management"]
inventory_collection = db["inventory"]

Defining the Inventory Schema

product = {
    "product_id": "SKU12345",
    "name": "Wireless Keyboard",
    "category": "Electronics",
    "quantity": 100,
    "reorder_level": 20,
    "last_updated": "2025-02-23"
}

inventory_collection.insert_one(product)

3. Python Automation for Stock Updates

To prevent stockouts, we automate reorder alerts when stock falls below the reorder level.

def check_reorder_levels():
    low_stock_items = inventory_collection.find({"quantity": {"$lt": 20}})
    for item in low_stock_items:
        print(f"⚠️ Low stock alert: {item['name']} (Stock: {item['quantity']})")

check_reorder_levels()

Automating Stock Adjustments

def update_stock(product_id, sold_quantity):
    inventory_collection.update_one(
        {"product_id": product_id},
        {"$inc": {"quantity": -sold_quantity}}
    )
    print(f"Stock updated for {product_id}: -{sold_quantity} units.")

update_stock("SKU12345", 5)

4. Pandas Stock Analysis

To analyze stock movement and optimize ordering, we use Pandas.

import pandas as pd

# Load inventory data into Pandas
inventory_data = list(inventory_collection.find({}, {"_id": 0}))
df = pd.DataFrame(inventory_data)

# Analyze stock levels
stock_summary = df.groupby("category")["quantity"].sum()
print(stock_summary)

# Export stock report
df.to_excel("warehouse_report.xlsx", index=False)

5. Real-Time Inventory Updates

To keep warehouse managers informed, we integrate real-time updates with MongoDB’s change streams.

from pymongo import MongoClient

def watch_inventory_changes():
    with inventory_collection.watch() as stream:
        for change in stream:
            print(f"🔄 Inventory Update: {change}")

watch_inventory_changes()

Conclusion

Automating warehouse management with Python, MongoDB, and Pandas reduces manual work, prevents stockouts, and optimizes inventory management.
