Whether an Internet hosting account meets the system requirements of your Internet sites and how easy it will be for you to manage that account are two rather important things. If you experience any difficulties or your sites just can't run on the web hosting platform since they were designed to run in a different system environment, it would be rather inconvenient in case you cannot get a complete or prorated refund and many companies on the market have such policies. That way, you'll end up losing money as you will not be able to use a service you've paid for. To be on the safe side, you'd better check the refund policies of any service provider before you buy a web hosting plan, so if you cannot work with your account or simply decide that you don't want to use it for any other reason, you can request a refund.
