We present NPointFunctions, a package to incorporate desired amplitudes and observables for an arbitrary BSM model in FlexibleSUSY. The package relies on the SARAH-generated output used with FeynArts/FormCalc, embedded in an appropriate way, thus allowing calculations up to one-loop level. The resulting tool is an extension to FlexibleSUSY, a generator of spectrum generator programs. NPointFunctions was designed to be customizable, modular and extensible with additional process- or amplitude- dependent contributions. We explain, how these goals are achieved, and discuss modifications to the default FlexibleSUSY workflow.
