How can we improve WHMCS?

As ClickMagick.com is great for tracking UTMS and tracking links already. Please consider a native integration with them. This way WHMCS owners would be able to easily track the performance of marketing in a much more efficient way. calcumte costs for traffic, sales, RIO, Lifetime customer value etc.

There is only one thing stopping this at this time, and that is the ability to add a hidden field on the order form or the registration page of WHMCS to populate a custom field.

We are provided with a tracking code by CLickMagick.com to go into the HEAD of every page and we can also already use the WHMCS hook feature to postback details of all sales / recurring revenue to CLickMagick...

The only thing left to solve or implement the ability to store the cmc_vid variable (that the header code from ClickMagick creates) into the client database when the client is added. Once populated this value never needs to change.

In my case, the following is all I would need to add to the order form and be able to get the entire thing to work is this

That's it.

But according to WHMCS support I am currently prevented from manually adding this to the form myself. :-(

If would be great to either have a standard field in the client database for a trackingID like the cmc_vid from Click Magick... Then a simple checkbox in the WHMCS settings to turn add/omit this hidden field... or please update the existing custom fields UI in the current WHMCS settings to enable Hidden fields on the order form and registration page and enter an initial value of [cmc_vid]

Please refer to this page from ClickMagick to see the only times when the [cmc_vid] is turned into the tracking ID which includes in URLs and also in form field values.

Adding this simple feature will enable one of the best third party tracking solutions to WHMCS.

Thanks for your consideration.
