I have a client that is wanting to move over to trello from Asana.
She is a website designer and adds her client to their project board. She needs them to be more than observers because they need to check off tasks in cards.
When she is adding clients to a board will she be charged for this? Or is that only if they are on another board as well?
And if not, is there an amount of board guests you can have total? Could she have more than 15 client boards with 1 client on each board? and if so would she be charged for this?
