Haus: Pay and split apartment bills with roommates (hausiq.com)

great idea for a startup! i'm a bit confused how everything is paid though, i'm assuming the joint payments get put in a singular account that the rental company pulls from...does this mean that rental services need to sign up too? A small graphic with like 3 steps (you sign up, they sign up, you pay your rent) or something would help clarify this immensely

I don't see the value over using something like Venmo or square cash.
