I want to ensure you'll be able to upgrade your QuickBooks to the newest version, @Practical.
You can subscribe to a new QuickBooks Online (QBO) account and access it on your desktop via a web browser. You simply need to go to the QBO log-in page and input your credentials so you can open your account. To get more information, you can visit this article: QuickBooks Online Mac and Windows Desktop App update.
Then, to subscribe for a new QBO you can go to the QuickBooks plans and pricing page. Once done, you can now access your QBO company on any device using a web browser.
Also, QBO has a compilation of how-to articles that will further guide you in optimizing your navigation. These include topics that start from setting up a company to running payroll for your employees.
As always, feel free to post here again if you have any other concerns about upgrading your QuickBooks version. I'll be right here to lend a helping hand. Take care always.
