Abstract: ATLAS has a wide programme to study the production cross section and decay properties of particles with beauty, as well as charmonium and bottomonium states. This paper covers only the ATLAS results in the domain of charmonium production, including J/$\psi$, $\psi(2S)$ and $\chi_c$ states, $B^+$ production, a brief discussion of the $\Upsilon$ states and updates on the $D(^*)$ meson cross-section analysis. The analyses discussed include double-differential production cross-section measurements of the J/$\psi$, $\psi(2S)$ and P-wave charmonium states $\chi_{cJ}$, extending upon previous measurements in precision and kinematic reach. Prompt and non-prompt modes are distinguished, as well as J/$\psi$ vs $\psi(2S)$ and the contribution to J/$\psi$ production from $\chi_c$ feed-down. Alongside the latter analysis, a competitive measurement of the branching fraction $B^\pm \rightarrow \chi_{c1} K^\pm$ was also performed. Results of these measurements are compared with the latest theoretical predictions from a variety of theoretical approaches.
