For most of my nine years in agencies, moving tasks along was the easy part. The hard part lived in spreadsheets: who was free next week, which hours never got logged, and whether a retainer still paid its way. I had a basic timer and a lot of tabs, and the tabs were always a few days behind. I work at Teamwork.com now, and I see the same thing in teams shopping for Trello alternatives. Trello is still a strong board, and Premium adds Timeline, Table, Calendar, Dashboard, and Map views.
