Hi Marge,
There is a work around that I found. Either before or after you set up a vendor change the asset/liability or whatever you want to use to an expense account. Set the vendor's default to that account, and after you save that go back to that account and change it back to whatever it was originally (asset/liability/etc). The default account for that vendor will then be the account you wanted even if it is not an expense. Please note that this may not work if you are trying to use a QBO default account that they don't allow modifications on.
Hope that helps. This worked for us and I imagine it will work for you, however manipulating the system like this must be done at your own risk.
