I was working in a small team earlier this year. We agreed at the beginning to discuss at the end how to split the funds we were getting to carry out the work.
We all know each other pretty well.
The process was new for us all and wasnt very smooth.
I think that having a bit more of a chat early on about how the money was going to be split may have helped.
We all agreed on a division at the end and are all still friends.
