If the account you need to adjust is not listed in the client trial balance, you can easily add a new account during the Journal Entry process, as per the below instructions:

1. Complete steps 1 through to 6 of Processing a Journal topic above;
2. Next to the dropdown box select the Add a custom account option;
   
3. Type in an account number for the new account;
   
4. Provide the new account with an appropriate description;
   
5. Continue filling out the remaining fields as you would to process a normal Adjusting journal;
6. Your new account and adjustment have now been completed.

TIP: If you do not know the clients account number required, use a unique account number to avoid duplication with the client's accounts (e.g. AUDIT1)
