QuickBooks Online (QBO) automatically maps invoice transactions to the default Accounts Receivable (A/R) account, which in this case is Araz2.
It's possible that this account has been renamed. To verify and make changes, follow these steps:
- Go to the + New menu and navigate to Transactions.
- Select Chart of Accounts.
- In the search bar, type Accounts Receivable (A/R).
- Locate the Accounts Receivable account that needs to be edited and click on it.
- From the dropdown menu, choose Edit.
- Make the necessary changes to the account name.
- Click Save to apply the changes.

By following these steps, you can confirm and update the name of the A/R account if needed.
