Form factors of $B_s^0\rightarrow D_s^{-}$ and $B_s^0\rightarrow D_s^{*-}$ are estimated for the whole physical region in the Salpeter method. We also apply the estimated form factors to branching ratios, CP asymmetries and polarization fractions of non-leptonic decays within the factorization approximation. The calculated decay rates agree well with the available experimental data. The direct CP asymmetries are found to be several percents at most. The longitudinal polarization fraction of $B_s\rightarrow D_s^*V(A)$ decays are $\sim0.8$ when $V(A)$ denotes a light meson, and are $\sim0.5$ when $V(A)$ denotes a $D_q$ ($q=d,s$) meson.
