No, that's absolutely not what I want. If I change the client's display name to the alias value, every transaction with them uses the display name. It's almost as if the real name for the company becomes an alias for the other name, instead of vice versa. What I'd prefer is a way so that I never see the alias value, but only the real company name, and if a payment is received using the alias name, it gets at least presumptively matched with an open invoice, just like QBO does now when a payment is received when the payor is a client..Yeah, I think this sort of might do that, but at the cost of hiding the real client name. If my client is XYZ Foods Corp. but the payments come in with a payor of "ABC Corp.(XYZ FDS Corp.) USD(Customer)" I don't want to see the alias in my list of clients, but the real client name.

I'm familiar with writing rules, but the QBO rule processor is just too limited for this. And display name just affects too much.

What would happen if I made the alias into a sub-client of the real client name? If a payment is received using the alias name, would QBO match it with an outstanding invoice issued to the parent client?
