Given the recent progress made in the automation of the virtual corrections at NLO in QCD, also the automation of the rest of the NLO computation is needed. In this talk I'll review the FKS subtraction formalism and how it's implemented in MadFKS. MadFKS is a code based upon the MadGraph/MadEvent Monte Carlo framework and computes cross sections and histograms for any process in any physics Model (Standard Model and BSM) implemented in MadGraph at NLO in QCD, provided that the finite parts of virtual origin are given by the user. For the moment it's restricted e+e- collisions. Reference: RF, Stefano Frixione, Fabio Maltoni & Tim Stelzer, arXiv:0908.4272 [hep-ph].
