I disabled the business network in accounts and settings, then found out there is another place it is enabled.  Even after shutting that off, it still pops up when I enter a new vendor.  So effing annoying!

For anyone who wants to know where the "hidden" one is go to

1. Accounts & Settings

2. Advanced tab

3. Business Network, click edit

4. Click on link to "go to my profile"

5. Disable both "Allow connections to pay me through the network" and "Allow members to find me in the network".
