How can I add a Vendor as an employee? I paid this person as Vendor before hiring them, and now QB Payroll keeps saying the name is already in use.

Recent versions of QB are unable to handle the {} braces:

If you're needing suggestions on how to slightly change a name, use * before or after their name. . 

Have a good day.

@Just_me I don't know who decided "necro-posting" was a bad thing, but they are dead wrong (pun-intended).

Commenting on old posts can be helpful.  Thing about them is that they tend to stick around.  In this case, this thread contains information that is out of date, which will cause new versions of software to break.  I found this post by using a search engine.  No one would ever complain about adding more context or corrections to an old Stack Overflow post.  /endrant

Now, regarding the possibly useful information contained in your post - can you add a little more detail to what you mean by "use * before or after their name"?  What does the asterisk do?  Is it printed on checks and included in generated invoices/statements?  Does Quickbooks handle the asterisk properly when generating paystubs?
