Hi Sam,

Post a receipt or payment in BR depending on whether the balance is too high or too low. Make the offsetting entry the bank account itself. The transaction will net to zero when it hits Ledger, but will move the BR balance in the direction you need.

I'd recommend doing this on a copy of the data to make sure you post a transaction of the correct type.

This s a good way of starting to use BR if you haven't completed a reconciliation. Just start with an opening balance of $0.00 for the account and then post the requisite receipt/payment to get the BR balance correct after the first reconciliation.
