I'm not at all comfortable suggesting OmniFocus is suitable for use as a CRM, though I'm sure there are some users that do it.

I'd use your office's accepted workflow and put projects and tasks in OmniFocus as appropriate, even if it means you have a task to sweep the daily ticklers out of your other system and review them for anything that requires more than a couple of minutes and then creating tasks or projects out of those.
