In this talk I will:

1) explain how photoelectron spectroscopy (PES) works and why it is useful;

2) give a quick overview of the methods available to compute photon-energy dependent PE spectra starting from the calculated density of states (and wave-functions);

3) argue why and when it is necessary to go beyond the electric dipole approximation;

4) show you examples of photoionization cross-sections computed within and beyond the electric dipole approximation for several atoms and one transition metal complex.
