License manager for a SC solution (for a project hosted)

Hi all,
I developed a solution (project) and I got a possible prospect that would like to implement it.
Is there a way to have a kind of license manager that check login and license keys . It could be possible that prospect use a bundle of license (i.e. till 5 users, from 6 users till 10 users…).
I’m not a programmer and I don’t know where to start … ;-( Have you got ready solution within SC or need I to use external license manager package ?
