Hello there, JennJoe88.
I understand your concerns about the functionality of QuickBooks Point of Sale v19 and how it will affect your business operations, particularly in terms of data management and transitioning from a multi-store setup to a single-store setup.
Keep in mind that since QuickBooks Point of Sale Payments will no longer be compatible with QuickBooks Point of Sale software after October 3, 2023, switching from a multi-store setup to a single-store setup may work, but it may have implications for your data and how it is managed. You can check out this article for more details: Discontinuation of QuickBooks Desktop Point of Sale FAQs.
I also suggest backing up your data before making any changes and reaching out to our Payments Team for guidance.
Keep me posted if you have any other questions about QB POS. Keep safe and have a good one!
