Welcome to the Community, @Tippy23. I can help by sharing information on how we handle this scenario to help you tracking your business seamlessly.
One self-employed business is equal to one QuickBooks Self-Employed (QBSE) account. This means it can only calculate quarterly tax payments for a single business and track income and expenses throughout the year. Thus, I recommend opening a second QBSE account if you run several independent firms.
If you’d like to create another QBSE account, check out our website for the updated pricing and detailed comparison of each version: https://quickbooks.intuit.com/self-employed/. Just use another email address to subscribe successfully.
You’ll want to consider using QuickBooks Online. This version allows you to have multiple companies under the same account. For additional information, please check this article: Create or add another company
In the meantime, I'm adding this article to learn more about helping your clients in tracking their self-employed income and expenses: QuickBooks Self-Employed Overview. It includes topics about entering business transactions, Schedule C categories, and tax payments to name a few.
Drop me a line if you need more help with customizing your sales forms in QuickBooks Online. I'd be happy to assist you. Thanks again for reaching us and have a great day.
