In the past 15 years, the development of radiative corrections and Monte Carlo generators for low-energy positron-electron ($e^+e^-$) data and $\tau$-lepton decays was the topic of the Radiative Corrections and Monte Carlo Generators for Low Energies Working Group (Radio MontCarLow WG). The group focused on facilitating the communication between theorists and experimentalists from the low-energy $e^+e^-$ field and $\tau$-community, which lead in 2010 to the publication of an highly cited report about the progress made towards precision hadronic physics at low energy.
Recently, parts of the Radio MonteCarLow Working Group program were included as a Joint Research Initiative in the group application of the European hadron physics community Strong2020. A goal of this working group is the production of the PrecisionSM database which is an annotated database for low-energy hadronic cross-sections in $e^+e^-$ collisions.

This proceeding reviews the results published by the Radio MonteCarLow Working Group and describes the status of the PrecisionSM database.
