CRM is a daunting concept, but it doesn’t have to be a monstrous undertaking.
Insightly gives you a simple and streamlined way to keep tabs on clients, current projects, and leads and opportunities. You can seed all of these entries with imported data, and then manage assignments and permissions on a user-by-user basis. Insightly also integrates with all kinds of third-party apps, including Evernote and MailChimp.
The basic version is free for up to 3 users, while $49 a month gets you up to 15 users and considerably more storage space.
