How can I invoice sales commission/expense without reflecting it in the invoice issued to the customer?

I'm here to help you create sales commission or expense without reflecting the issued invoice, accounts-medvall.

You can write an expense to separate the deduction of your income. Here's how:

1. Click + New, then select Expense.
2. Select a Payee.
3. In the Payment account field, select the account you used to pay for the expense.
4. In the Category details section, enter the expense info.
5. In the Category drop-down, select the expense account you use to track expense transactions.
6. Complete other fields.
7. When you're done, click Save and close.

Upon sharing this, I still recommend consulting with your accountant. They can check if creating a sales commission or expense without reflecting the issued invoice is right for you.

If you need to see the income and expenses for each customer, you can run the Income by Customer Summary report.

In case you want to delete the expense, here's how:

1. Go to Expenses.
2. Find the expense you want to delete.
3. Select View/Edit ▼ dropdown in the Action column, then select Delete.
4. Select Yes to confirm that you want to delete the transaction.
    

Once you delete an expense, it disappears from reports. But you can still see a record of it in the Audit log.
