I want to upgrade to Essentials and the quoted yearly price is $273 a year but when I click on choose plan the checkout price is $382 a year.

Welcome to the Community, @capuano-t2-optus.

I'll help you reach our Product help and support team for an update about the updated plans and pricing.

You can click this link to start a chat with them: Product Help and Support. You can ask for an assistance in upgrading your plan to get the exact price quoted.

Also check on this link: Plans and Pricing. It also has a link at the upper right of the page to reach the sales support team. See the screenshot below.

Here is an article to also guide you in upgrading your plan: Upgrade or downgrade your QuickBooks Online edition.

I'm also adding this link to help you get started with QuickBooks Online when you decide to get a new subscription with us: Get started with QuickBooks.

Let me know if you have questions about QuickBooks plans and pricing. I'm always here to help. Have a great day.
