Hello, ConnextHosting has begun offering WHMCS v4 Design Integrations for just $20.00 AUD! This does not include administration area. We can also do integrations for versions below v4 Guaranteed 1 hour turnaround time AFTER your order has been accepted. Unfortunately not all of our staff members are able to perform this task, meaning your order will be accepted as soon as possible but can take up to 12-24 hours. A demo of our work, our own billing system for ConnextHosting Click Here - Website design here. If interested, you can purchase integration here - $20.00 AUD Where it says FTP username and password we recommend creating a seperate FTP account for your billing directory instead of giving us your website's login. Also - if you change website designs, we offer 2 free re-designs. URL: http://www.connexthosting.com.au Thanks, ConnextHosting
