Hello there, @Friends Properties.
If you want to purchase QuickBooks Online (QBO), I recommend contacting our support team. They have the proper tools to place an order or subscription depending on what version suits your company and the core features that will help you run your business.
Once you already have the online version, you can use this article for the steps on how to convert your company file from QuickBooks Desktop to Online: Move your QuickBooks Desktop file to QuickBooks Online.
To ensure that your books match, you can run one of your financial reports in QuickBooks Desktop and Online to check if your import is successful.

Please let me know how this goes or check back if you need help with QBO. Have a great day!
