I want to use Trello to work with several different "one time " customer every week.. To managesmall project so we don't get lost
those customer will access the board for a day, hours, 2 days...The time I finished their project (always short in time)
I want to keep those boards as the info is valuable to me for other contract with other new customers. (my own Knowledge base)
If I subscribe to Trello to get unlimited board (keep the old ones I do not use but keep them in case I need some info from them), if I want " one time customer " to collaborate with me, on their board, for hours, 1-2-3 days,
DO THEY NEED TO ALSO PAY ?
IF YES, is the only way for me to not pay for them is to give them a PUBLIC access in READ ACCESS MODE only ?
