I agree that the ability to add vendor type is necessary. I just had a client  as me to do something that I have done in QB Desktop in the past using the Vendor Type field. Hard to believe it can't be done in QBO. QBO even has a Supplier Type field where we can choose individual or business. Why not just allow the option to add custom choices in that field? I hope you add this feature soon. The workarounds suggested are not viable. I already use classes for other purposes. It would be far too time consuming to tag every invoice and there is a high risk of error - forgetting to do it or choosing the wrong tag. And while the notes are a workaround, it is not a good option since I can't choose from a drop-down list - risk of error. Plus I use the notes for other things.
