If you acquire a hosting server with the idea to start your own hosting company and to resell plans to various people, you may as well need to sell domains, to give your customers the opportunity to acquire everything they want for their new website from just a single place. Becoming a certified registrar involves thousands of dollars along with tons of documentation, so the easiest solution is to sign up for a domain reseller account with a current registrar company. Your reseller website will be linked to that account via the registrar's API. Using this type of account has a large number of pros - all your customers will be able to obtain and to control new domains comfortably; the cost of a new registration is lower as compared to what you would have to spend as an end customer; what's more you're able to start reselling right away. The registrar businesses that offer domain reseller accounts generally require some money as a deposit.
