I have several clients and I keep their contact info or login info in a spreadsheet with the hours worked. I can paste the info into each project description but seems clunky. Using JIRA CORE. Checked out components but not sure if that would work for me.
Loving how I can track each project task! Before JIRA (which I used at previous employers and loved) I had my tasks in Outlook Tasks so big improvement. Still would like to have the info readily available. I have used Confluence a lot so am open to that.
