Tools. You don’t need much to work as a home-based freelance writer, but there are some tools that you must have. The most important will be your computer. Get the fastest Internet access that you can afford. It doesn’t matter what kind of computer you get. Just make sure you’re comfortable enough to spend a lot of time with it. Most clients will request that you submit your work as a Microsoft Word document, so make sure that whatever programs you use are compatible. In addition, because you’ll be spending so much time at the computer, make sure that you have a good work area with proper lighting. Some clients will want to be able to reach you by phone or Skype, so have both set up and accessible. You’ll need an invoicing program, such as Freshbooks, and a good bookkeeping system to keep track of sales, orders, and accounts receivables.
Research individual companies in your desired niche: If possible, it’s always better to become an affiliate directly with a company (if they have an internal affiliate program), as no one else will be dipping into your commission rate. This is the preferred route for most of the prominent affiliate marketers, including Pat Flynn. Unfortunately, it’s also the most work, as you’ll have to do the research yourself to see who offers programs (they’re usually listed in the website footer).
