Client follow-ups, hands down. Not the big stuff - the constant small stuff. "Are we still on for Thursday?" "Did you get my last message?" "Just checking in on the quote." It's rarely more than a two-line answer, but multiply that by every active client and it eats an hour a day I don't actually have.
If I could hand it off, it'd be all the routine check-ins and status updates - job confirmations, "on our way" heads-ups, gentle nudges on quotes that have gone quiet - so I'm only stepping in for the conversations that actually need a person.
