Tracking an account is important for maintaining accurate financial records and monitoring business performance. To make sure we are aligned, I can think of two possible scenarios regarding what you mean, Gearedu.
If you're trying to create a service or a non-inventory item and did not manually assign an Income account in the field, the system will automatically default it to the Sales account. However, you have the option to choose an Income account to track your items by clicking the dropdown arrow. To do so, follow the steps provided below:
- Navigate to the Gear icon and then Products and services.
- Select the New button in the upper-right corner and choose Service or Non-inventory.
- Enter the necessary information. Under the Income account field, click the drop-down arrow to select the appropriate option.

- Click Save and close.
On the other hand, if you're getting the " There is no income account associated with the item "Sales" error, may I know where exactly you encounter this in QuickBooks Online (QBO) so we can check and verify and be able to address the issue?
