I have self employed income from separate businesses. How can I categorise them so income is not all in one total?

QuickBooks Self-Employed allows you to track one Business type per company file, ClareS. 

The option to have a separate Business income type is unavailable. You can only choose one transaction or include the other to have one total income account. If you opt to categorise only one, you'll have to exclude the other. You can also subscribe to another QBSE account for the other Business income. 

If these transactions are downloaded from the connected bank, view the details to check the Exclude this transaction box. 

Here are few article that will give you more details about managing your transactions:

• Custom categories in QuickBooks Self-Employed
• Manually add transactions in QuickBooks Self-Employed
