How/where do you guys install your WHMCS on a multisite?

Hey

I get that the connector/app for Wordpress and WHMCS means it can reside anywhere. Theoretically.

If i install it in the main account of the network ftp, it becomes accessible under all domain mapped sites, correct? So
mynetwork.com/whmcs/
= subsite.network.com/whmcs/

Which is undesireable.

I was leaning to making a new account in whm, and giving this a clients.network.com address, then installing whmcs in root folder on that account.

Would that be bad practice, or could anyone see any problems with that portal existing outside of the main domain for content benefits?
