Is there a way/how do you:

I have a business client that has multiple salespeople. Salespeople are sent their own invoices but payment to me comes from the main company, so many invoices paid in one check.

I would like to keep the salespeople separate (no joint portal access) for privacy and reporting purposes, but have the main company as an "umbrella" since they pay me in one check. It's easier to apply payments.

Is there a way to have one main company, but separate portal access for each contact person?

Would it be easier to use Tags for salespeople and disable the portal for everyone?

What do you do?
