I appreciate your time checking this with the QuickBooks Community, @jasongiamanco.
I want to make sure I provide you the right resolution, I only need a few more information about the issue.
Are you trying to change your vendor's name type as a customer? If so, you can export the vendors' list and import it back to QuickBooks Online (QBO).
For additional reference, you can check this article: Change vendor, customer or employee name type.
However, if you're referring to something else any details you can provide is extremely helpful for us to narrow things down.
I'll be around to help if you have other questions. Have a good day ahead.
