The refund policy of each web hosting company you choose is quite important as there's always a chance that the service may not cover all of the requirements for your script-driven applications to function correctly, you may have difficulties to manage the account or you might simply decide that you do not want to use the site anymore if, for example, you see that it is not doing very well. In any of the aforementioned cases, you'll lose your money if your web hosting provider does not give refunds, even partial ones. In this light, taking a look at the refund policies of each company you consider to sign up with will be a guarantee that this will not happen. The policies vary from one company to another and a refund may be offered for different time periods.
