why i can't edit my initial cost

It's my top priority to ensure you're able to edit your initial cost, MarkWang.

One possible reason you're unable to update the initial cost is you already have transactions that affect your inventory count. If so, I'd suggest contacting our QuickBooks Support Team. They're equipped with tools to help you with the process.

Here's how:

1. Click the (?) Help icon in the upper right-hand corner of the Dashboard.
2. Select Talk to a Human.
3. Enter a short description of your concern and press Enter.
4. Click I still need a human.
5. Select Contact Us to connect with our live support.
6. Choose Get a callback.
   

Otherwise, I'd suggest accessing your QuickBooks Online account via a private window. This doesn't use the existing cache files, which makes it a good place to determine if this is a browser-related issue.

Here are the keyboard shortcuts: 

• Safari: Command + Shift + N 
• Google Chrome: CTRL + Shift + N
• Mozilla Firefox or Microsoft Edge: CTRL + Shift + P 

Once logged in, update the initial cost. If you're able to do so, let's clear the browser's cache. This removes its stored cache to ensure the program performs efficiently.

If private browsing doesn't work, I'd recommend using other supported browsers. They'll provide the best and most secure experience with QuickBooks. 

Aside from that, you also have to ensure you have access to update the cost. 

Additionally, I've included these articles that'll help you track what you sell and manage your products and services in QuickBooks Online.
