Supply Chain Management for E-commerce: A Complete Guide

Supply chain management (SCM) is the backbone of any successful e-commerce business. An efficient supply chain reduces costs, improves delivery times, and enhances customer satisfaction. This guide covers everything you need to know about managing your e-commerce supply chain effectively.

What is E-commerce Supply Chain Management?

E-commerce supply chain management encompasses all activities involved in getting products from suppliers to customers:

Sourcing - Finding and selecting suppliers

Procurement - Purchasing inventory

Warehousing - Storing products

Inventory Management - Tracking stock levels

Order Fulfillment - Picking, packing, shipping

Delivery - Last-mile transportation

Returns - Reverse logistics

The E-commerce Supply Chain Flow

Supplier → Manufacturer → Distributor → Warehouse → Customer
                              ↓
                        Returns Processing

• Lower capital requirements
• Less control over fulfillment

3. Warehouse Operations

Warehouse location factors:

• Proximity to customers
