Beginning balance off by over $3,600
I reconcile my accounts by hand. Always have, and most likely, always will. Today I went to reconcile my account and noticed that the beginning balance was off by over $3,600. I verified the ending date of the last statement, and beginning date of the new statement, and everything looks correct. I've never had a discrepancy like this before. What could have caused it, and how do I correct it?
