We would recommend opening a new bank nominal here to keep a clear audit trail of transactions and the accounts they hit.
You can set up a new Bank Nominal by:
From the DPS Home screen select Nominal.
Select Nominal Accounts.
Select New.
Complete the fields (Client bank would be Balance Sheet, Client Bank) then click Save.
Once the new bank has been created From the DPS Home screen select Nominal.
Select Nominal Ledger.
Select Journals.
Make 1 journal, transferring the balance from Old Client Bank to the New Client Bank and Post.
Once complete, From the DPS Home Screen select Tools.
Select Default Nominals.
Assign the new Default Client Bank from Old Client Bank to the New Client Bank. (If you have separate branches, this would need to be set for each branch.)
Click Save.
Any residual unreconciled items on the Old Client Bank can be then reconciled as and when the transactions clear that account, on your final statements from them.
Please consider if any of your letterheads and/or bill templates need to be updated with your new bank details. If so please raise a new case online and reference the title of this article.
