How would you verify an online business like a bookkeeper?

Not sure of the best place to post this so here it goes.

I've talked with an online bookkeeper that I like quite well. They handle other investors, seem to get it, etc. We've discussed how they'll access accounts with view only logins, etc so I feel pretty good about trusting them but I've never hired anyone that wasn't local. Is there anything I should do or get from them to verify them as a company before moving forward?
