I am so tired of getting the same response from QBO people for the last 2 years. "Rest assured that I'll pass along your suggestion to our Product Developers. They're always looking for ideas to consider on how to improve QuickBooks Online (QBO)."  Yeah, Yeah, sure.....Always the same line, over and over again.  Your product developers are asleep and have deaf ears.  

THIS IS NOT IMPOSSIBLE NOR IS IT TERRIBLY DIFFICULT FOR A GOOD SOFTWARE DEVELOPER TO ACCOMPLISH!!!  QBO users SHOULD NOT HAVE TO USE 3rd PARTY SOFTWARE TO GET LINE ITEM NUMBERS TO SHOW ON THE INVOICES/QUOTES THEY SEND TO THEIR CUSTOMERS.  We all pay enough for QBO every month.  QBO should be providing us with what we need, instead of sending us to other developers.  I'm really tired of the "I'll pass it along for you....."   When you can tell me that it is going to finally be a feature for QBO then I'd like to hear from you.  But the same old line is really not doing anything but frustrating many of your subscribers.
