You probably have a weird process for invoicing, ordering, paying, etc that makes sense to no-one but you, because it's never had to. I would have her come in and get your process streamlined and rationalized so that someone else can do it. Like a temporary consulting gig. Then hire someone to do it. Maybe that someone ends up being her, but the plan should be that it's not.

Personally I could never work with my wife. We think too differently. She wouldn't understand why I might spend 4 hours working without saying a word to her even if she is at a desk 10 feet away, I wouldn't understand why she's constantly bothering me.
