I understand QBs does certain automatic adjustments at year end. 

1) But what exactly triggers that? (if there is no closing date set)

2) Which specific year end adjustments do I need to make, before QBs does it's adjustments?

3)  What if I haven't made any adjusting entries yet, does QBs still do the automatic adjusting entries?

PLEASE don't cut/paste a reply, pointing me to find an accountant!  I need real answered here.

If some of the top community contributors could jump in here, I would greatly appreciate it.

Thanks so much!
