You can't make your clients do anything
You can't force clients to take your advice or hold up their end. Show them the upside and the downside, then raise your prices if nothing moves.

You can’t make your clients do anything.
You can’t make them take your advice. Or execute a promise they said they would make. Or deliver things to you on time.
All you can do is show them the benefits of doing so and the downsides if they don’t. After that, their success or failure is on them.
Don’t try to convince or manage your clients too hard. It won’t work.
Raise your prices instead. It usually forces action one way or another.
