Hi there, MBOpsGuyatBAW.

In the online version of QuickBooks, you have the option to enter more than two decimal points in the quantity and rate field. The total amount will rounded off only until 2 decimals. 

To help you manage your transactions, you can use these articles: 

• What is the difference between bills, checks, and expenses?
• Customize reports in QuickBooks Online
• Set up and track your inventory in QuickBooks Online

Let me know if you have other questions in handling your transactions. Take care!
