To best serve you, we are offering three buy options currently. If you have internal IT team to support the web server and database server, you can choose the "on site installation" option. If you prefer to install the application on your site but without IT team to manage the server, we can do it for you remotely at very low cost. This is the "on-site installation with remote managenent". Otherwise, we are pleased to host this application for your company with our option "off-site hosted". We are implementing a tight security policy to make sure all your company data in our database are safe. You can also use an external link to link the sensentive data to our database while the critical data are in your company site.
