Who doesn't like easy money? Well, now you can cash in on those word of mouth recommendations to your colleagues about Google Apps for Business. Through a new Referral Program, every time a person you know signs up for the corporate-minded services, you'll get a $15 kickback via direct deposit. There's no limit to the number of customers you can refer, however there's a 100 user max per customer account. When you consider that the program pays per user, this makes sense. After submitting name, email and a tax ID number, users receive a unique referral link to share. Once that link is used... boom, money in the bank.
