Hello there, @LaughingYeti. I want to ensure this will be taken care of so you'll get back to working order.

Thanks for joining this thread. To clarify, may I know where specific part of the transactions for vendors you want to select the COGS and any other account? In QuickBooks, you have the ability to choose any type of accounts depending on the entry you're trying to input. Any additional information you can provide is a great help so I can give a timely solution. 

For further guidance managing expense transactions, feel free to browse this page: Manage vendors.

I'm always here ready to lend a hand if you have any other concerns managing your expense transactions in QuickBooks. Have a good one and stay safe.
