We derive new, very precise estimates for averages of arithmetic functions over friable integers from analytic information on their associated Dirichlet series. These yield significant improvements upon available results in classical cases, in particular concerning the effective expansion of abstract main terms of de Bruijn type. These results also permit new applications, linked to the solubility of polynomial equations.
