Thanks for following up with the Community, JC5970.
 

Intuit only offers QuickBooks with subscriptions. There's no longer a standalone version which can be purchased. You can purchase a subscription for QuickBooks Pro 2024 through our Sales team.

They can be reached while you're using QuickBooks.
 

Here's how:

1. In your top menu bar, go to Help, then QuickBooks Desktop Help.
   
   
    
2. Click Contact Us.
   
   
    
3. Enter a brief description of the issue in our Ask a question (or tell us what's wrong) field, then hit Continue.
   
   
    
4. Select We’ll contact you for a callback or Message Us to start an instant messaging session.

Be sure to review their support hours so you'll know when agents are available. You'll also want to be aware that Pro subscriptions will no longer be sold after July 31, 2024. After this date, you may be able to obtain it through an authorized reseller.

You can also confirm our current prices for different QuickBooks products and initiate subscriptions through our Pricing page.
 

To answer your other question, all QuickBooks products that aren't discontinued are supported by Intuit with security updates, live technical support, etc. After May 31, 2024, all 2021 versions of QuickBooks will be discontinued. You can learn more by reviewing our Service discontinuation policy article.
