Can't be sure about US rules, I don't see why the settlement makes a difference once you pay and have a paper trail for your business but hey I could be way off base

Strike has a business app you can sign up for if you're looking for a dashboard to manage this but not sure if they have integration with accounting software, so you'll likely need to do this manually inputting into Quickbooks

You can try using a company like - https://www.bitwage.com/ if you're open to involving a third party and https://bitpay.com/send/payroll/ also offers the service and maybe they'll be able to direct you on local rules
