Juggling systems is goofy but as long as they&#x27;re web based it&#x27;s easy, go old school<p>+customer data folder
++customer name &gt; links to trello,slack go here
+++project name &gt; links to trello etc. go here<p>then I have a todo.md or todo.txt using imdone-atom with snippits, gives you a text based kanban, you can open project folders with atom --add c:\customers\abc\project1 and alt-t for tasks<p>also alt-j is journal where you can try to kanban all customers if you&#x27;re ocd<p>documentation should not go in a ticket system, it should go in a wiki<p>my fav is a combo of integrated apps like trello&#x2F;slack, jira&#x2F;confluence, github&#x2F;gitter<p>tasks are todo&#x2F;doing&#x2F;done and done includes closing their ticket system and updating their wiki or whatever they&#x27;re using like a wiki
