... Women (with and without dependent children) of this business type are distributed fairly equally across urban and rural areas. It is striking that a higher proportion of these businesses than home-based businesses on average had increased their turnover in the previous two years, which contradicts the view that 'mumpreneur' businesses are of marginal relevance in terms of turnover and value added (Thompson et al. 2009). The second distinct group of business owners run the business from home because of their own illness or disability or care of an elderly or disabled person. ...
There are a lot of items that can be purchased very inexpensively at garage sales or thrift stores and sold for higher prices elsewhere. A few years ago I discovered that I could purchase good hardcover books at my local thrift shop for $1 or less. I realized that some of them could be sold on Amazon.com for $15-$20, which turns out to be a pretty decent profit.
Define your product or service. Starting an online business gives you the benefit of having access to millions of customers, but you also have a lot more competition. No matter what you're trying to sell, you can bet that hundreds more online retailers have a similar idea. What differentiates your product from other similar products? To help your product stand apart from the rest, you'll need to find a niche.[1]
When one of your customers makes a purchase, you purchase the product from a third-party company (the drop shipper, usually a manufacturer or wholesaler) for a lower price. This process is as simple as forwarding the order from your customer, a process that can actually be completely automated. (Remember you don't have any risk here of buying inventory because the sale has already been made).
Set up a merchant account. Service businesses in the past had to generally rely on cash or check—setting up an entire credit card processing system was a thankless, expensive task at best. Using a service such as PayPal makes it possible to accept virtually any form of credit or debit card for your services, and includes dispute resolution should the need arise (and it will arise).[6]

Another idea someone could do from home is to start a service or write a software program that scours local ad listings (like craigslist) for a particular used item a person wants to buy. They have services like this for new items, but not used. I know others like me who are keeping their eye out for something used (like a canopy king bed!) but don’t have the time or inclination to search for it every day.
One way to stand out from the competition with a drop shipping business is to private label your products. This simply means you put your own label/brand on the products that the manufacturer is creating. That way you're not selling the same product brand and just competing on price; rather you can use your own brand and face less competition. Think about when you're looking at medicine at the pharmacy; the brand names sell for higher prices and people think they are different from the generic brands even though the ingredients are exactly the same.
