Quickbooks desktop EOL

I believe it is still supported, they just aren't selling to new users so I don't think you have to worry about making a jump quite yet.

Edit -  Personally, I use Sage for my own firm accounting.

Clients needed to go with Plus (leasing).

"After July 31, 2024, customers without an active QuickBooks subscription will no longer be able to purchase QuickBooks Desktop Pro or Premier, QuickBooks Desktop Mac, and QuickBooks Desktop Enhanced Payroll. This change will not impact the following QuickBooks subscribers:

• Existing QuickBooks Desktop Plus and Desktop Payroll subscribers can continue to renew their subscriptions after July 31, 2024.
• QuickBooks Desktop Enterprise products are also not impacted by this change, and customers can continue to purchase Enterprise subscriptions after July 31, 2024.
• QuickBooks Desktop Pro Plus, Premier Plus, Mac Plus, and Desktop Enhanced Payroll will not be discontinued. This is a stop sell only for new purchases, not a discontinuation (sunset) of this product line. Existing subscribers of these products can continue to renew their subscriptions after July 31, 2024."

You can still get Accountant (Pro/Premier) last I looked. I no longer beta test.

A solid choice is to keep using QuickBooks Desktop via a hosted service. Apps4Rent offers a dependable cloud hosting environment for QuickBooks Desktop, allowing your clients to access it remotely with a stable connection without needing to change software.
