I appreciate you coming into this thread, jiminok. I can share information when integrating QuickBooks Desktop Point of Sales into Desktop Enterprise.

As shared on this thread, QBDT POS was discontinued on October 03, 2023. All associated services connected to this program are now discontinued. However, QuickBooks Enterprise (QBES) remains fully functional for managing financial transactions. While you can continue utilizing the POS system for store management, you will no longer receive critical security patches and updates. I recommend checking out this guide for additional inputs: QuickBooks Desktop Point of Sale discontinuation.

Alternatively, you can explore using third-party applications to implement modern retail solutions with QuickBooks Desktop Financial Software. This will allow you to integrate and link transactions into the program that best suits your business.

Furthermore, you can refer to this resource to learn how to track customer transactions in QuickBooks Desktop: Get started with customer transaction workflows in QuickBooks Desktop.

I'll always be around on this thread if there's anything else you need further assistance with when managing transactions in your file. Keep safe and have a great day ahead.
