Recording your transactions the right way is a good exercise for preventing errors in your books. I'll be glad to steer you in the right direction so you can focus on doing the things you enjoy.

Doing this will help prevent any future discrepancies in your books. You can also reach out to accounting professionals on our site using this link here.
