Thanks for joining this discussion, @PhilG,

If the adjustments made creates a discrepancy in the bank balance, you must undo the reconciliation. You need to go through this method to make sure the register's balance matches the bank statement and the trial balance.

The steps are simple. Add the adjusted amount in the register and manually reconcile it. Here's how to mark a transaction as reconciled:

1. From the left navigation panel, select Accounting menu then go to Chart of Accounts.
2. Locate the account and select View register to reveal the transactions.
3. Run through the list until you find the adjusted amount, then go to the status column indicated with a check mark on the header.
4. Click on it multiple times until it shows a letter R. This status means that the transaction is included in the reconciliation.

Please note that the ending balance of a reconciliation becomes the beginning balance of the following period. Every adjustment made to a previous reconciliation that changes the register's balance requires reconciling the following period again.
