ACS - My name on pay slips are different from my official name on passport

Hi,
So I have a preferred name in my company. And it happens that they use this name on my pay slips. In the company’s reference letter, it was said that I was otherwise know as “preferred name”. Is this enough or must I do more to get my employment approved by ACS?

If the company document mentions both names clearly and one of them matches with passport, then you should be fine.
