Do you have a contact management system that will be suitable with todoist?
It seems for me that you system is very cool.
But do you have a suggestion for me regarding using a contact/client management that will be good using it with you system?
if you're using GMail or Google Apps, you could use it to manage your contacts and work with one of Todoist's numerous plugins - for Chrome: http://todoist.com/chrome or Firefox: http://todoist.com/firefox or, if you're not using any of these browsers or not using GMail, you can try Todoist Anywhere http://todoist.com/anywhere which allows you to access Todoist anytime while using any web-based contact manager.
If you prefer managing your contacts with Outlook, we also offer an Outlook plugin: http://todoist.com/outlook or if you're using a Mac - a Mac app: http://todoist.com/macApp
