Whether a hosting account meets the system requirements of your sites and how easy it will be for you to manage that account are two really important matters. In case you experience any kind of troubles or your websites simply cannot work on the web hosting platform due to the fact that they were designed to run in a different system environment, it would be rather annoying in case you cannot get a full or prorated refund and various companies on the market have such policies. Thus, you'll end up losing funds as you will not be able to use a service you've paid for. To be on the safe side, you should check the refund policies of any company before you acquire an internet hosting plan, so in case you cannot use your account or simply decide that you do not want to use it for whatever reason, you can request your money back.
