Hi there, @Luluwawa.

I'm here to share some steps on what's the best thing to do to handle your invoice transaction in QuickBooks Online.

You'll need to change the income account of the premium so it will be separated from the revenue. You can select your preferred account so the amount will be recorded accurately.

To do that:

1. Go to Gear icon at the top.
2. Select Products and Services.
3. From the Action column of the appropriate item, select Edit.
4. From the Income account ▼ drop-down, choose the account you want to use. 

If you're unable to see the account, make sure the account's detail type is Sales of Product Income.

Here's how to check the detail type:

1. Go to Gear icon at the top.
2. Select Chart of Accounts.
3. From the Action drop-down of the account, select Edit.
4. Change the detail type to Sales of Product Income if necessary.
5. Select Save and close.

For more details about this process, please see this reference: Change the account for a product/service item.

I've also added this link that can guide you in tracking payments in QBO: Learn how to receive and record the accounting for invoice payments.

Let me know if you need more help in managing your accounts. I'll make sure you're all set. Have a great day!
