Hi there, @dhavalkakadiya.

As my colleague Mich_S mentioned above, yes, the QuickBooks Desktop Point of Sale 19.0 will discontinue on October 03, 2023. Together with the other software features stated by her.

The QuickBooks Desktop Point of Sale 19.0 is the latest and last version of POS. This means that the option to upgrade to a newer one is no longer available in QuickBooks.

However, if you're referring to upgrading your QuickBooks Desktop (QBDT) subscription, you can refer to this article on how: Upgrade QuickBooks Desktop Pro, Premier, or Enterprise.

For detailed information, kindly visit: QuickBooks Desktop service discontinuation policy.

Moreover, I'll also share this link where you can search for articles that can serve as your reference to guide you manage your QBDT file: QuickBooks Desktop Help Articles.
