We compute the B{sub s{yields}}f{sub 0}(980) transition form factors using light-cone QCD sum rules at leading order in the strong coupling constant, and also including an estimate of next-to-leading order corrections. We use the results to predict the branching fractions of the rare decay modes B{sub s{yields}}f{sub 0}l{sup +}l{sup -} and B{sub s{yields}}f{sub 0{nu}{nu}}, which turn out to be O(10{sup -7}) (B{sub s{yields}}f{sub 0}(980)l{sup +}l{sup -}, with l=e, {mu}), O(10{sup -8}) (B{sub s{yields}}f{sub 0}(980){tau}{sup +{tau}-}) and O(10{sup -6}) (B{sub s{yields}}f{sub 0}(980){nu}{nu}). We also predict the branching ratio of B{sub s{yields}}J/{psi}f{sub 0}(980) decay under the factorization assumption, and discuss the role of this channel for the determination of the B{sub s} mixing phase compared to the golden mode B{sub s{yields}}J/{psi}{phi}. As a last application, we consider D{sub s{yields}}f{sub 0} form factors, providing a determination of the branching ratio of D{sub s{yields}}f{sub 0}e{sup +{nu}}{sub e}.
