What's the one office job you still do after the last job of the day?

Curious how other owners handle this. The field work runs fine, but every evening there's the same pile: quotes that never got a follow-up, invoices past 30 days, and customers waiting on a reply to "when can you come out?"

If you could hand ONE of those to someone else tomorrow, which would it be? And has anything (a hire, an automation, a routine) actually stuck for you?
