Importing bills with item details is currently not supported in QuickBooks Online (QBO). The program only supports importing specific fields for your bills, Emmanuel.

You can consider exploring third-party applications that allow importing of bills to include the item details.

Here's how:

1. Go to Apps and select Find apps.
2. In the search field, type in keywords like importing bills.
3. Click the application's tile to view more details about it.

To have the option to import your bills to include the item details, I recommend submitting feedback to our product engineers. They're responsible for analyzing and researching user requests for possible inclusion in the program.

You can run the supplier total report to view all payments you made to them.
