Good day, Sgroove. Let's get this sorted out.

You can use the mark-up feature in QuickBooks Online to automatically add the $0.25 as income to every payout. Here's how:

1. Click the Gear icon at the upper right corner, then choose Account and Settings.
   
2. Go to Advanced.
3. From the Chart of Accounts, click the Markup income account and choose the correct income account.
4. Tap Save.
5. Hit Done.
    

Once done, you can now see this commission to your expenses.
