Hello there, svcfo.

I understand that it is important for you to upgrade from QuickBooks Desktop (QBDT) Premier 2021 to a newer version due to its discontinuation after May 31, 2024.

Please note that QuickBooks Desktop Premier 2024 is no longer available for purchase. Since you're using standalone QBDT Premier, the available option we can offer for you is to move your data to QuickBooks Online (QBO) for the flexibility to work from anywhere. If you have larger businesses with complex needs, we also suggest utilizing QuickBooks Desktop Enterprise.

I see that these options don't meet your business needs. Please know that we still offer QuickBooks Desktop Plus subscriptions before July 31, 2024. It is a subscription-based service. Once you get this before July 31, 2024, you'll be able to continue to renew after the said date. You can visit this article to get more details: Buy QuickBooks Desktop Premier Plus. 

To make this possible, I recommend reaching out to our Sales Team. Although you've already contacted one of them, they would be the best people to assist you with this. Their contact details can be found in the Purchase QuickBooks Desktop Plus before the cut-off date section.

Additionally, you can go to the Customer Account Management Portal to easily manage various aspects of your account, including the ability to view and manage your subscriptions, update your payment method, and download any products you have purchased.

I am always here to help you with any details you need about purchasing in QuickBooks Desktop. Please feel free to post your questions.
