Actually for work in commercial, ACCA is more than enough.

When u already got ACCA + ur working experience in difference industry, this can consider very good.

Remember when u go to interview for job, people will be more interesting on what u can contribute to his firm but not certificate. For eg, 2 people go to interview, A only got ACCA but know have very good working experience + strong leadership, B got ACCA + MBA + ICSA but only work for few years and leadership not so strong. Finally, the boss will choose A.

So unless you are interest for further study or want to become lecturer, otherwise all this thing won't be so important after u getting ACCA.
