After a short motivation for non-minimal SUSY models I will introduce a framework to study SUSY models beyond the MSSM using the Mathematica package SARAH. The main part of the talk will focus on two aspects. First, the automatized calculation of two-loop Higgs masses using SARAH/SPheno for a large variety of SUSY models with the same precision public codes provide today for the MSSM is explained. I will also discuss results for important corrections in the NMSSM in the large lambda-limit which have been calculated for the first time with this setup. Second, the automatized calculation of quark and lepton flavour violating observables at one-loop using the FlavorKit interface between FeynArts/FormCalc, SARAH, and SPheno is presented. I will also discuss short examples how the user can implement easily new observables and -- if there is time -- also new Wilson coefficients.
