In this presentation, I will discuss the tremendous progress in high-precision simulations for the Large Hadron Collider (LHC) in the past few years. The focus will be on the inclusion of next-to-next-to-leading-order perturbative corrections in parton-shower generators (NNLO+PS). After mentioning the existing NNLO+PS methods, I will present highlights of phenomenological results obtained with the so-called MiNNLO approach. I will further discuss the inclusion of beyond-Standard-Model effects in these calculations through Standard Model Effective Field Theory (SMEFT). Precision simulations have applications also beyond the LHC. Besides their relevance for future colliders, such as the currently most likely programme of an FCC-ee, an application to accurately model the prompt neutrino background for neutrino telescopes (e.g. ICECUBE) will be presented. Finally, I will introduce a novel idea to include higher-order corrections in event simulations through a recursive approach.
