We present the possibility of calculating the quark flavor changing neutral current decays B0s → ℓ¯ℓ and B0d → ℓ¯ℓ for a large variety of supersymmetric models. For this purpose, the complete one-loop calculation has been implemented in a generic form in the Mathematica package SARAH. This information is used by SARAH to generate Fortran source code for SPheno for a numerical evaluation of these processes in a given model. We comment also on the possibility to use this setup for non-supersymmetric models.
