Want to start a reselling business from home but don’t have inventory?
Or maybe you’re tired of sourcing, storing, and shipping products yourself?

Welcome to the world of product sourcing and dropshipping—the 2025 way to build a profitable side hustle with minimal upfront costs and no warehouse needed.

Whether you’re a beginner or a gig worker looking to increase your income online, this guide breaks down how to start reselling using sourcing and dropshipping, plus tips, tools, and real-world examples to help you succeed.

What Is Product Sourcing?

Product sourcing is the process of finding products to resell—whether online or offline.

You can source inventory in multiple ways:

• Buying retail overstock

• Thrifting secondhand goods

• Purchasing wholesale or liquidation lots

• Partnering with a dropshipping supplier who ships for you

In 2025, the most scalable strategies mix AI-driven demand forecasting with supplier integrations—like what platforms such as Closo now offer.

What Is Dropshipping (and Why It’s Perfect for Beginners)?

Dropshipping is a fulfillment method where you sell a product but never hold the inventory yourself. Instead:

• A buyer places an order through your online store or resale account

• You forward the order to a third-party supplier

• They pack and ship the item directly to your customer

• You earn the profit difference between your price and their cost

No inventory. No upfront stock. No storage or shipping hassle.

That’s why dropshipping is one of the easiest ways to start reselling from home—even if you’re working full-time or living in a small apartment.
