It's completely insane to me that QBO does not currently have such fundamental field (Customer, Member or Account Number). How's that even possible in the technology era we are in?? Guys, it's 2021??!!!

I found a way to add customer information to the left of the company name (attached sample invoice), but I think you get what's the problem we will all run into with this "plumber" method, right?

I case it didn't click, here's some of them: how do one sort by company name, issues with searches etc. 

I found many other threads about this topic and people complaining about it for years now!

<<<<<!!!!!  When will QB finally listen to its customers and take ownership of this limitation (which affects ALL OF ITS CUSTOMERS) and fix this? Rudimentary Customer Information form need....  !!!!!>>>>>   Any other stupid system out there has a "Unique Customer ID" field.  Please shake internal teams up and let's fix this guys!! 21st Century....
