I tired marketing like promoting certain product and tng code to client, i had bad experience since these are only earn when u are able to sell.
Not even in mid tier / big 4 , i am in small company , the overburden issue are miscommunication and keep doing simple mistake as well my efficiency and capabilities , also the lack of staff contributed to the cause since high turnover employee expected every year and rigorous key in very detail stuff take a toll of my mental and a lot job beside audit too.

i will consider the option u mention . Thanks
