You don’t have to pay rent. Other than possibly upgrading your internet service to allow for more speed, working from home won’t cost you any more than your current living expenses. Find an unused corner in the basement, work out of your guest room, or clear off your dining room table. Your apartment rent or mortgage payment won’t change, and you’re utilizing the space you have anyway to actually make money.
Many small companies simply don't have the time or staff to properly run their billing operations. That's where entrepreneurs who want to offer invoicing, bookkeeping, human resources and other clerical services to business owners on a contractual or part-time basis come in. With just a laptop and a few clients, you can get the ball rolling from home.
Outsourcing is the new and dominant wave of the business world. As businesses shed employees, they increasingly turn to independent contractors to supply what in-house staff used to do. One of the ways they do this is through virtual assistants. These are people who provide certain tasks online. Businesses can use virtual assistants as much or as little as they need to. If you can make yourself available to multiple businesses, you might have plenty of work without ever leaving your house.
There are two basic markets you can sell to: consumer and business. These divisions are fairly obvious. For example, if you're selling women’s clothing from a retail store, your target market is consumers; if you're selling office supplies, your target market is businesses (this is referred to as “B2B” sales). In some cases—for example, if you run a printing business—you may be marketing to both businesses and individuals.
