Bookkeeper

I have multiple business interests, and need to set up a couple of them in accounting software from scratch and then maintain the books on a monthly basis. I'd like to use WAVE as it is easiest for multiple businesses under the same account, but if someone has better experience in QB or Xero and it could be cost effective, I'd look at that. Someone experienced in day to day expenses, payables, and general accounting for small business would be ideal.
