1. Onetab (Quick save all tabs, nice chronological grouping)
2. Google Docs (Powerful enough for most businesses)
3. Freshbooks (Free up to 3 clients - worth the upgrade after)
4. Mailchimp (Free up to 12,000 emails and 2,000 subscribers, and worth paying for after also)
5. Insightly (CRM free up to 3 users, 2,500 contacts. Which is a great start)
6. Inspectlet (Like Crazyegg, except they have a free option)
7. Asana (Great PM/Task with a generous free product)
8. Evernote/Skitch (MUST HAVE!. Every entrepreneur needs a way to compile their thoughts and research. I find this so important to even finding more about myself as I look back at the things I saved)
9. Trello (PM for creatives.)
Then you have of course, Skype and Google Analytics which require no explanation.
