Bank Reconciliation
Am a novice here, so bear with me please.
Affiliated with a non-profit and just finished entering 4 years worth of data so we can file back taxes and hopefully get our 501(c)(3) back. I have been reconciling the bank account for every month. My use of QB is fairly straight forward (cash basis) and have only one inventoried item we sell, a ceramic mug.
At the beginning of this 4 years (2017), we purchased 300 of said mugs for $840.53 and we wrote a check. Not knowing any better, I entered said item into inventory with a starting qty of 300, without any connection to the check we wrote.
Now, I am finishing up the 4 years of data, and have a better (not good) understanding of how inventory works within QB. So, in my ignorance, I deleted the check I wrote 4 years ago, entered a bill for the mugs, along with qty and price/mug and re-entered the old check number to pay the bill. I manually reconciled that particular check assuming that was the correct thing to do.
Now I try to reconcile Sept 2021, and my beginning balance does not match my bank statement. It is off exactly $840.53. Obviously I don't understand what I did wrong.
Question: Do I want to just enter the correct opening balance in my reconciliation, or is there a way to fix what I have done? I would prefer the fix method, but I might have entered a black hole.
