The refund policy of each internet hosting provider you select is really important as there is always a possibility that the service may not cover all requirements for your script-driven apps to function correctly, you may have difficulties to maintain the account or you could simply decide that you don't want to work with the Internet site anymore if, for example, you see that it isn't doing very well. In any of the abovementioned cases, you'll lose your money in case the web hosting provider does not give refunds, even partial ones. In this light, checking the refund policies of any company you consider to register with will be a warranty that this won't happen. The policies differ from one company to another and a refund may be offered for different periods of time.
