Hello there, shediyahtherapeu.
QuickBooks Self-Employed is designed for Independent Contractors. It has the ability to keep track of all your transactions. However, some features that you may need to handle LTD company are not available on this platform.
The Online product and QuickBooks Self-Employed are two different versions. QuickBooks Online is for Small Businesses that allows you to select a type of company and industry. With that, we can use the QuickBooks Online version to manage an LTD company. If you consider this, you'll have to register your company to HMRC to get this thing done.
You can check this link to see the comparison of each version: https://quickbooks.intuit.com/aag/accountants/compchart/. Also, you can check this article for additional details: How to Start Your Own Company.
Please visit here again. I'd be glad to have you back and help you in any way that I can. Take care and have a good one!
