Invoices show up in QuickBooks Online (QBO) based on how you’ve categorized the items or services on the invoice, and the accounts tied to those items in your Products and Services List, Paul.
When you create an invoice, income is automatically categorized based on the income account linked to the product or service you are selling. To check or update the account tied to a product or service in the Products and Services List:
- Go to Sales, then Products and Services from the left-hand navigation menu.
- Locate the product or service you added to the invoice.
- Click the Edit button next to the item.

- Look for the Income Account field—it shows where revenue from this item is categorized in your Chart of Accounts.

After saving the invoice, QuickBooks automatically posts revenue to the Chart of Accounts under the associated Income Account. Here’s how to locate the revenue in your Chart of Accounts:
- Go to Accounting, then Chart of Accounts.
- Find the account tied to your product or service.
- Click View/Register or Run Report to see invoice transactions posted to that account.

Ensure the Income Account linked to your product or service is correctly set to post revenue under the desired category, such as Service Income.
