The refund policy of each web hosting company you select is really important as there is always a chance that the service might not cover all of the requirements for your script-driven apps to run the right way, you could have difficulties to manage the account or you might simply decide that you don't want to use the site anymore if, for instance, you see that it is not doing very well. In any of the aforementioned cases, you will lose your money in case your hosting provider does not give refunds, even partial ones. In this light, taking a look at the refund policies of each and every company you consider to register with will be a warranty that this cannot happen. The policies vary from one company to another and a refund may be offered for various periods of time.
