I'm glad you visited us here in the Community, airmilitairellc.

Let me share some insights on how income accounts for different platforms work in QuickBooks Online (QBO).

From the information you provided, it sounds like you want to set a default income account for your products and services. If so, you can definitely assign a specific income account for products and services.

Let me show you how:

1. Click the Gear icon, then choose Products and services.
2. Select Edit just beside the product or service or click New.
3. Scroll down and under Income Account drop-down, select the appropriate account.
4. Click Save and close.

Let me know if you need anything else. I'm always ready to assist. Have a great day.
