If you have the polyatomic ion in the same form, such as an SO4 on both sides of the equation, balance it as one piece. If you have one SO4 on the reactant side and three SO4's on the product side, place a three in front of the compound containing the SO4 on the reactant side and continue balancing everything else from that point.
