Original Post:
A good team handles splitting revenue internally. If you all don't have the legal and logistical financial and fiduciary means to handle all this, then maybe being a 'team' may be a bit much. Some of the best 'teams' for indie projects are one or two main devs (usually programmers) and one or more contractors (usually artists) that perform 'work for hire' at a flat rate.
EDIT:
I posted this comment over 270+ days ago (as of this edit) and still get PMs/DMs about it. Oof. I've changed my mind, are ya'll happy? :P Leaving the original post for posterity/archival. Working alongside indie devs in a community Discord server does wonders for that. Also Toby Fox himself and his cohort 'temmie' both expressed support for making things easier on indie devs. I won't go against Mr and Ms UnderTale ;)

But what if it's a hobby project with people across the planet, earning only $50 (random value) a month? It's probably not worth digging into the legal stuff, but it's still fair to share with the other team members..
While, in my eyes, for Itch it would be just paying out different people. I don't think it adds much to the legal stuff they have to get into.
People that want to handle it internally still can.
