Thanks for joining this conversation, @gilrane. I'd be glad to provide information concerning inventory by weight in QuickBooks Online.

Consider looking for a third-party app that allows you to sell your products by count or weight. To do so, you can go to the QuickBooks Apps Center. Alternatively, you can search through the Apps menu in QBO.

Here’s how:

1. On the left panel, click Apps.
2. Go to the Find Apps tab.
3. Use the search bar and enter the keyword to look for an app.
   
   

Additionally, I'll share with you these articles for your guide:

• Apps that work with QuickBooks.
• Install and use apps.
  
  

Please let me know if you need clarification about this, or there's anything else I can do for you. I'll be standing by for your response. Have a great day and stay safe.
