I will go ahead and start casually saying the amount owed. Like I said, I would much rather be paid the proper amount minus tip then get extra one time, and less than why I'm owed the next.
If you are an occasional sitter and willing to take a check, that should take care of the problem. Most sitters don't want checks.
