We introduce the Next-to-Minimal extension of the SOFTSUSY~program which calculates the sparticle spectrum in the Next-to-Minimal Supersymmetric Standard Model (NMSSM). The NMSSM is an extension of the Minimal Supersymmetric Standard Model (MSSM) with one additional singlet superfield, which can solve the mu-problem of the MSSM and help ameliorate the little hierarchy problem. SOFTSUSY can calculate the spectrum for both the Z3 conserving and Z3 violating cases.
