RSUs - A General Survey

We are seeing an increase in our clients issuing RSUs, and unlike my clients in CA (I am in NM now), they need quite a bit more guidance with the internal processes for RSUs.  I am trying to get a general feel for how other (smaller) companies handle these so we can provide some 'standard practice' info to our clients, so I'm hoping to get some feedback here from those of you who regularly work with RSUs, specifically re:

1. Settlement schedule: Are companies settling each RSU at each vesting milestone, or do you find that they're doing it on a set schedule for all outstanding RSUs (e.g., first of every month, quarterly, etc)?

2. Taxes: Are companies handling the withholding internally, or do they engage with firms that specialize in this?  Are payroll services generally experienced with this, or do they need a specific service? (assuming they are unable to handle internally)

Thanks in advance!
