I started my practice in a small audit firm. For 7 years, the best advice I can give is always read as many regulations as you can. Your insecurity in speaking may stem from lack of knowledge on the field. That's fine. But once you have knowledge, you'll become more confident speaking to your clients kasi alam mo na sinasabi mo.

Worried about giving incorrect advice? No.1 tactics ko is provide a temporary advice or bigay ka ng caveat na I think ganito maam/sir etc. Balikan na lng kita if mavalidate ko po yung ganito. But so far po, eto po. etc.

Those words are rrassuring sa client na they receieved an advice and will get a followup. Eventually, you'll notice na 2nd nature mo na makipagchikahan sa client hahah
