Beginning bank balance changed in the middle of the month, how is that possible?

Thanks for reaching out to us, @userquin. I'm here to lend a hand.

Some factors affect the beginning balance to be incorrect. These are due to the following:

• Someone entered an incorrect opening balance when they created the account in QuickBooks.
• Someone added transactions that are older than the opening balance but didn't edit the original opening balance entry to reflect the change.
• Someone edited, deleted, moved, or unreconciled an already reconciled transaction. This changes the ending balance of your last reconciliation, which impacts the beginning balance of the next one.
• Someone manually reconciled a transaction, so it didn't show up on the next reconciliation.

To rectify the issue, follow the below steps:

1. Review the original opening balance since it’s the starting point for accounts in QuickBooks. If the information is incorrect, it affects all of your reconciliations.
2. Check your bank statement and make sure that you are reconciling the correct account for the correct month.
   1. Sign in to your QuickBooks Online (QBO) account.
   2. Click on Accounting at the left pane.
   3. Select Reconcile.
   4. Review the account you selected in the Account dropdown menu.
3. If your account is connected to online banking, categorize and match all of your downloaded transactions to make sure everything is in balance.
4. Lastly, run the discrepancy report to check for changes that affect the beginning balance. From there, you can make some updates depending on the notification under the Change Type column.
