One of the original reasons we created WHMCS User and IP Control was to allow admins more control over their order process .  A few had come up to us with the request that they be able to lock orders to a certain country (theirs), and so we put this together.

With WHMCS User and IP Control, you can easily block access and orders from certain countries (say, if you’re not legally permitted to do business there), or lock access and orders down to your country alone. No more htaccess edits needed
