Hi there, @ChrisBCI!

I'd be glad to redirect you to the best help available.

We have a separate forum called Intuit Developers Forum where you can ask and get helped about your concern on merged vendors in the QBO API. I suggest starting the same discussion there through this link: https://help.developer.intuit.com/s. Different developers, engineers, and programmers would be glad to help you out.

Please know you can always get back to us here in the QuickBooks Community if you have any "How Do I" or navigation questions. Have a great day!
