New results on charm and beauty electroproduction from the H1 and ZEUS Collaborations at the ep collider HERA are presented. Differential cross sections are compared to a next-to-leading order QCD calculation. The heavy quark contributions, F_2^{ cc} and F_2^{ bb}, to the proton structure function F_2 are compared using different experimental techniques. Also, results are shown on the charm fragmentation function, thereby testing the universality of fragmentation.
