Hello there, @AML67. I'll chime in on this thread to share additional insights about QuickBooks Desktop (QBDT) support discontinuation.

Beforehand, may I know if you have encountered any specific error messages while trying to access or open your QBDT company to view your data?

You're correct that QBDT for UK customers and support will end on June 30, 2023. This means there will be no more updates, and you will have to troubleshoot all the issues manually.

Regarding your QBDT Pro 2013 Disk, since it is an outdated version of the product, I recommend reaching out to the QuickBooks Data Services team to assist you with accessing your company data. See this article for more details and FAQs to contact them: QuickBooks Data Services FAQ.

To learn more about our service discontinuation policy, kindly refer to this article: QuickBooks Desktop discontinuation support. This includes frequently asked questions about this policy.

Please comment on this thread if you have more QuickBooks-related questions or concerns. I'll get back to you as soon as possible. Stay safe!
