Accounting for completed tasks, scoring system. Kanban?

Question

Project management

IT outsourcing + service for individuals. We use Trello. But there is a lack of accounting for completed tasks. You have to count with your hands.
Example: Todoist karma. Done great. Plan for the day, plan for the week. Count.
Has anyone encountered a similar one, but in one service? Kanban board + points for tasks.
Thanks in advance.

Answer 1

Try LeanKit, the interface is a bit old, but the flexibility of the board is the best I've seen + there is accounting.
