How to to banking/bill pay with property management

[Beary Bowles]

Hello all

I've been managing my 12 unit apartment building that I've purchased for about two years. For the first time I'm hiring a property manager and she's experienced but (4yrs experience) with units managed up to 120 units. One of the hang ups is she wants pay the bill but asked me how do I pay. I've been paying through my business account bill pay. Should I allow her access into my account, open a separate account, or how should I construct this so she can handle the bills? Any advise would be great.
