Don't really want to but in, but I would encourage that your company invests into an actual WHMCS license. Normally those nulled versions have had some major editing that you may run into some issues in the future with unauthorized access by others risking your clients information with being revealed publicly. You may also want to look into getting an SSL for your "Client Area" as this will also help your customers know that their information is stored securely.

Just an opinion, and I hope you take these into consideration considering you've posted on a discussion forum requesting opinions and feedback.
