Let me share more details about invoices, Roxror.

Once you create an invoice, it'll automatically affect the Accounts Receivable and the product's Income Account.

The best way to reflect it on the different income accounts is to set up three cabbages (products) and three income accounts. Then, assign each cabbage to their respective income accounts.

For easier tracking, you can create subaccounts in your Chart of Accounts. Also, here's how to add product and service items to QuickBooks Online. If you want to edit the items, you can go back to the Products and Services tab and update them at any time.
