Change product / service on invoice line item without deleting description / quantity / rate

I run into this issue periodically, and each time I check to see if Intuit has "fixed" this issue...  Looks like NOT...

It is such a pain to manually update the line with the old information.  Why won't you fix this Intuit?  

I'll add, Instead we get a new, difficult to navigate, interface for chart of accounts, that replaces an interface that was working just fine. So Intuit gives us what we don't want... And won't give us what we have been asking for over 5 years...  

Fix the BUG please - I have 1000s of sales receipts to change.

Give your customers the option to keep your fantastically 'as designed' (by an idiot) feature or allow us to retain the information when assigning to a new product because some other person (idiot) in my company has assigned the wrong product.

I came here looking for an answer to the same problem. The original post was from 2019. It's now 2023. Intuit regularly raises their rates for their customers, but where is the development? Do you care about your customers' needs at all or is it time for me to find help with a competitor?

This was an option in general settings on QBD. Why would you take it away on QBO? Please bring it back. 

This is APPALLING. I'm so used to using Freshbooks that I keep trying to go in and change something only to have the entire entry be cleared out! Even a 10 year old could code this better. HERE ILL HAVE GPT DO IT FOR YOU. It's so painfully clear that you don't have actual engineers on deck just a bunch of SEA code jockeys who couldn't program their way out of a paper bag. This software is disgusting and I actually hate it but my accountants put me on here last year and now I have to fight with them to change back to Freshbooks. Competency Crisis is real, folks! You're witnessing it first hand. 

Oh yeah here's your code. GO FIX IT. 

using System;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.EntityFrameworkCore;

namespace YourNamespace
{
public class Service
{
public int Id { get; set; }
public string Name { get; set; }
public string Description { get; set; }
}

public class YourDbContext : DbContext
{
public DbSet<Service> Services { get; set; }

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
// Replace with your actual connection string
optionsBuilder.UseSqlServer("YourConnectionString");
}
}

public class ServiceManager
{
private readonly YourDbContext _context;

public ServiceManager(YourDbContext context)
{
_context = context;
}

public async Task AddServiceIfNotExistsAsync(string name, string description)
{
// Check if the service already exists in the database
var existingService = await _context.Services
.Where(s => s.Name == name)
.FirstOrDefaultAsync();

if (existingService == null)
{
// If service does not exist, create and add the new service
var newService = new Service
{
Name = name,
Description = description
};

_context.Services.Add(newService);
await _context.SaveChangesAsync();
Console.WriteLine("Service added to the database.");
}
else
{
Console.WriteLine("Service already exists in the database.");
}
}
}

class Program
{
static async Task Main(string[] args)
{
using (var context = new YourDbContext())
{
var serviceManager = new ServiceManager(context);

// Replace with the name and description of the service you want to check/add
string serviceName = "Example Service";
string serviceDescription = "This is a description of the example service.";

await serviceManager.AddServiceIfNotExistsAsync(serviceName, serviceDescription);
}
}
}
}

This remains the most obtuse and difficult thing I've been dealing with since switching to Quickbooks Online in 2014.  I sometimes need to change the product/service so it matches the right Income account (i.e. set it as a service for building website, but then realize, sometimes when generating tax reports, that it should be Sales of Product Income (for infrastructure resources, etc.), so I change the Product/service to get the right income account - but lose everything that has already been invoiced for the sake of accurate accounting).  Bah!  So many, many years building web systems for my customers, and yet the accounting web system I use can't implement a simple ("Do you want to clear your existing values?" prompt)...  Just, tired of this...
