Technically, if you do some custom development and charge for your time , once the client pays its theirs, unless a contract states otherwise.

That is pretty much the definition of "work for hire" - and the opposite is true when you work as a freelancer. The client receives a copy, and license to use. You retain full rights unless stipulated otherwise.
