Run the final walkthrough so nothing falls off the list
Paper lists are easy to lose. Write each touch-up down once, with its room, and close out the job at 0.
Write it down once, with the room
Add each item while the homeowner points at it, so nobody has to remember which bathroom.
Agree on the count before you leave
Read the count back in the driveway. A homeowner may want the list finished before the final payment.
Put it back, don't start a new note
When a touch-up comes back, put that item back on the list. The count stays honest.
