A bail bond is basically a contract between a person accused of a crime and an agent called a bondsman. Bondsmen pay the entire amount of a suspect’s bail in return for a fee called a premium, which is typically 10 percent of the entire bail amount. The bondsman keeps this fee when the accused is released from jail. The latter then agrees to show up in court for trial; and if they choose not to (skipping bail), the bondsman enlists the help of bail enforcement agents (aka bounty hunters) to track down the accused and bring him/her back to court, thereby preventing the forfeiture of the bail money paid by the bondsman.
Of course, one is not and will never be encouraged to have a run-in with the law, because a police record isn’t a good thing to have at any time of day.
