My statement and register agree on the balance. However, when I try to continue to reconcile, the reconciliation tool says that my opening balance is off.

We can resolve the prompt you're receiving by reviewing the opening balance for the account you're reconciling in QuickBooks Online (QBO), @ghartmanwi.

Since you've indicated that the reconciliation tool has prompted a message regarding your balance, it sounds like you've reconciled this account in the past. Such note typically indicate that changes have occurred to your cleared transactions since your last reconciliation. To handle this, let’s double-check the Opening Balance Equity account in the bank register to clarify the beginning balance.

1. Go to Transactions, then Chart of accounts.
2. Locate the account, then View register.
3. Search for Opening Balance Equity account.
4. Take note of the date and balance.
   
   

If your account is connected to online banking, ensure you've matched and categorized all downloaded transactions before you start reconciling. Everything must be categorized to get the correct final beginning balance.

On the other hand, if the reconciliation tool pertains specifically to the opening balance, I recommend following the steps detailed above about checking the opening balance to verify it.
