Hello there, KenRea.
Yes, the maximum number of total names in QuickBooks Pro/Premier is 14, 500.
You can read more about the maximum number of list entries in QuickBooks Desktop in this article: Maximum number of list entries (list limits and custom fields).
If you've reached the maximum number of entries and require more, you'll need to manually delete some Employees, Customers, Vendors, and Other Names combined. Because the QuickBooks Desktop version you're using doesn't have an option to delete multiple names or entries.
You can also check out this link and look for a third-party application that will help you delete multiple name entries.
If you have any further questions about adding and deleting customers in QuickBooks Desktop, please let me know; I'm always happy to help. Have a wonderful day!
