Inside IR35 Subcontractors

I’m interested to hear from any companies in the UK who manage subcontractors, off-payroll workers who are considered within IR35, inside of IFS.

For example, do you allow them access to IFS for timesheet entry and how do you manage their user/employee files within IFS so as to meet UK tax rules.

Any examples of where you are doing this currently would really help.

Thanks in advance
