A pitch that bounces before, or on, the plate is exactly the same as any other pitch- with one lone exception. It can never be a called (non-swinging) strike.
The pitch can be batted into play, it can be swung at and missed or it can hit the batter. If it does hit the batter, it is subject to all of the usual requirements for awarding first base (effort to avoid, in/out of the strike zone, etc.).
The rule is the same for any level of either baseball or softball.
