I can provide insights on integrating QuickBooks Desktop Point of Sale (POS) with QuickBooks Desktop Enterprise.

As mentioned in this thread, QuickBooks Desktop POS was officially discontinued on October 3, 2023. This means all related services associated with this software are no longer available.

However, QuickBooks Enterprise (QBES) continues to function effectively for managing financial transactions. While you can still use the POS system for store management, it is important to note that you will not receive essential security updates and patches moving forward.

For more detailed information on this discontinuation, I recommend reviewing the guide on QuickBooks Desktop Point of Sale discontinuation.

As a workaround, you can use third-party applications that provide modern retail solutions alongside QuickBooks Desktop Financial Software. These alternatives can help you integrate and manage transactions in a way that aligns with your business needs.
