What happens is that a company gets a subpoena from a party in a lawsuit, criminal or civil. The company has to comply, if they don't the party issuing the subpoena can go to court and make a motion asking the court to order the company to comply with the subpoena. At this point it is a court order so much more serious not to comply. Nobody at the company gets reimbursed for their time. So sometimes in civil case, companies drag their feet knowing that the requester will have to get a court order for their to be teeth. Now if the prosecution has issued the subpoena (be that state prosecutor or federal) you are risking more because it is the state or federal government issuing the subpoena. If the company feels a subpoena is unduly burdensome (would cost too much money) they can make a motion to quash the subpoena or, when the party goes to get a court order file a response saying "this is really burdensome, we aren't likely to have responsive records, etc." MOO (as an attorney who has written/issued numerous administrative subpoenas).
