Hello, @Serge01.

When creating a bill, the terms you've assigned to a specific supplier should automatically be automatically included. Let's make sure to remove the default bill payment terms set up in your QuickBooks account.

Here's how:

1. Go to the Gear Icon.
2. Choose Account and Settings.
3. Select the Expenses menu.
4. From the Bills and expenses section, click the Pencil Icon.
5. Remove the default bill payment terms.
6. Click the Save button.
7. Hit Done.

Once completed, you can try creating a bill again. 

On the other hand, you can generate and customize your Transaction List by Supplier report. This way you'd see a list of your transactions grouped by supplier.

Here's how:

1. Go to the Reports menu.
2. Scroll down to the Expenses and Suppliers section.
3. Choose the Transaction List by Supplier.
4. Click the Gear icon above the Amount column.
5. Make sure to mark the Terms tick box. 
6. Click the Run Report button.
