Hopefully you've already called ADP directly and asked. I deal with another provider but do know that I can stop payrolls if I do it quickly before the actual process date (I send them on Monday and they are processed on Wednesday). Do you have that same type of time lag?
Agreed. I have used ADP (a lot) and you call them up and tell them to kill the payroll. You must do this quickly.
I never had a problem with it. You just write down the number of your agent, call them up, and tell them to "kill the payroll I just sent". Give them the company code if you have more then one company. It is a good idea to have regular conversations with your agent.
