Hi, MoleD. Yes, we can customise the Supplier Contact List report to only display the subcontactors. This customization option is available in QuickBooks Online Advanced.
Here's how to do it:
- From the Reports on the left menu, select Standard reports.
- Search and select the Supplier Contact List.
- Click the Customise button and go to the Columns section.
- Go to More Columns, then click Show more under Supplier.
- Check the Subcontractor box.
- Scroll back to Filters and set the following: Subcontractor, equals, and Yes.
If you're using QuickBooks Online Plus and other plans, we can provide an alternative. You can click Add notes to the supplier profiles as indicators that they are CIS Subcontractors. You can refer to the screenshot below.

Then, you can pull up the same report (Supplier Contact List) and add the Note column. Afterwards, you can export the report to Excel and filter the list to subcontractors only.
Let us know if you need anything else. We're here to help.
