I was looking for the same thing but I guess its not possible. It seems like it would be easy to add this feature.... I need to be able to edit a product/service and its really counterintuitive that we cannot. It doesn't allow for us to have a quicker more efficient workflow in creating invoices for different clients with the same product/service. If I make one product for one client, then i have to change the name of the product for the next client even though the product should be named the same. We also cannot edit it or delete it if we make a mistake which makes absolutely no sense. At this point, using Google Sheets would be quicker than using Quickbooks because of this.
