It's been 3+ years since the OP on this. What the F is happening over there? This is a very basic functionality. 

Add this to a growing list of inconveniences, I'm bummed I just bought a year's sub to this platform. 

Long story short, because of various reasons I have to stick with Quickbooks for now. I am now getting a prorated refund of Self Employed and upgrading to Essentials. I need to be able to itemize "Other Business Expenses" category on my P&L for the Schedule C because you have to itemize when you file your taxes. This with the need to edit Products or Services that I create, I have to do Essentials, which costs more of course. 

For some of you the cheaper Simple Start should be enough, and you will be able to edit products or services in invoices, just not the itemization of other business expenses. 

I hear your sentiments, @JHTP.

I recognize the convenience of editing your products/services in QuickBooks Self-Employed (QBSE). I also understand that you want to make some changes and improvements to the program to meet your business needs. However, at this time, there's no integrated way to edit products/services in QBSE is unavailable.

It's completely asinine that editing/deleting services/products isn't an option when it's fundamental for invoicing, regardless if you're a company or self-employed.

But my favorite part is about all this is all the copy/paste responses from QB moderators have been to click on "Assistant" to send feedback, but when you currently click on "Assistant", this dialog pops up:

"The Digital Assistant is no longer available here. We
apologize for any inconvenience.
We are still here to support you!

articles or select Contact Us."

And when you click "Contact Us", it very literally sends you this community forum where there's so many posts complaining without any resolve, LMAO

How many years of people posting and commenting that this is an issue that needs to be addressed will it take for them to finally implement it? This is beyond frustrating.
