A new service was raised with the wrong account category. Invoices have gone to the wrong account in the general ledger. Can the account postings be fixed except by JE?

You'll need to create a Journal entry, keith. I'll be here to share with you the steps on you to make one.

Journal Entries helps you transfer the amount posted from the wrong account to the correct one. While doing this, I'd recommend consulting an accountant for guidance, so your account stays accurate.

Here's how:

1. Locate the + New button.
2. Choose Journal entry.
   
3. On the first line, select an account from the Account field. Depending on if you need to debit or credit the account, enter the amount in the correct column.
4. From the next line, pick the other account you're moving money to or from.
5. Review the amounts. It should have the same amount in the Credit column on one line and the Debit column on the other.
6. Fill in the other necessary fields.
7. Once done, hit Save and close or Save and new.
