The mathematical understanding of scattering theory in Quantum Electrodynamics progressed substantially over the last two decades. Two non-perturbative approaches to the subject has been pursued: Non-relativistic Quantum Electrodynamics and relativistic (algebraic) Quantum Field Theory. This talk compares these two approaches and presents some first steps towards their consolidation. In particular, it is pointed out that the concept of inclusive collision cross-sections, familiar from perturbative Quantum Electrodynamics, has meaningful counterparts in both non-perturbative approaches.
