Well, first of all, I would like to know, if you have any preferences because there are multiple options after Bachelor’s in Commerce but running behind the best isn’t going to help you in any way. First of all, you definitely may be having some goal in your mind about what you would like to be and do in future. Depending on that, I would recommend you to go for the master’s program.
B.com is accepted as an entry for Masters provided you have good marks, sound knowledge of the language - IELTS for English (if English is not your mother tongue) or for a German programs a C1 or C2 in German. For job market it depends on your employer. These days a B. COM is not sufficient to enter any decent job in Germany. I recommend you to research, based on your interest.
Hope this helps!
