But does this really play out well over time? In my experience, no. People change. People's needs change. And that's a good thing. But if you're splitting things say 50/50 Brushwork vs Bookwork, or whatever, it's not going to be too terribly long before one of you reaches or surpasses the other in your respective 'specialty'. At what point does that initially perceived equal division begin to tilt? Because you can 100% guarantee its going to. And now what?
Or, better yet, what happens when your growth outpaces your partners abilities? You've done well after two years but the books and all the managerial grind are too much. You hire an accountant, a lawyer etc. Now what's this guy really brining to the table in a still equitable amount?
Too messy. You need a book keeper? Hire one! You only have to pay them, not split any and every cent with them. AND you can always fire them if something goes wonky. Which will always happen.
