Collisions of electrons with protons at a centre-of-mass energy of 318 GeV are being recorded by the two experiments H1 and ZEUS at the ep accelerator HERA at DESY, Hamburg (Germany). Measurements involving beauty and charm quarks, performed by these experiments, provide a good environment to test perturbative QCD predictions as the large quark mass supplies a hard scale. Recent measurements of beauty and charm production in ep collisions are presented here. QCD predictions at next-to-leading order are found to generally agree with the measurements. Beauty measurements however are sometimes slightly higher than the predicted cross sections. Beauty and charm contributions to the proton structure were also measured and are well described by QCD predictions.
