Almost no business can operate without the right software. When it comes to selecting software for business purposes, business owners should carefully consider all pros and cons of the suggested options. Generally, there are two alternatives: commercial and free software. Leaving aside the possible license issues of using free software for profit generation, I'd like to focus here on the evident benefits of free software for business needs.
The most obvious and the most important advantage of using free and open source software is the absence of fees. It is easy to understand why. Who would like to spend extra money if the same (or maybe even better) software is available free of cost? For example, WPS Office lets users save 2/3 of the purchase price on a yearly MS Office Professional license. Free Google Analytics is way more popular than paid analytics solutions by Adobe or Kissmetrics. There is no particular point in purchasing paid software only because it may potentially add some extra value.
Basic functionality is enough
If your business is not related to computer animation or professional design service, you may pass on the purchase of Photoshop license for creating and editing images. Just think it over, Photoshop provides a great deal of options that you will hardly ever use. Gimp or Pixlr photo editors do not have such extended functionality, but do their basic job amazingly well. Indeed, the most common software tasks are the easiest ones. For example, Freemake Video Converter offers several additional PRO packages, but the majority of users are quite happy without them, as the software covers all the major video conversion needs.
