I'm currently transitioning to bookkeeper and I have a QBO certificate and a Level 2 Certificate but i still feel like I'm not confident enough to do work especially the excel file since I had never tried it. I've been applying a lot of entry level bookkeeping roles and rejected a lot of times due to experience. Can someone give me advice or anyone who can help me with this? I seriously wanted to be train by someone and see him/her as my goal.
