Google on Monday announced a new App Referral Program aimed to spread the use of Google Apps for Business through word of mouth. Under the program, the company is encouraging people to refer Google Apps to their friends, family, and even businesses. And guess what? There are rewards for it. Every time you refer someone and they actually sign up, you get $15, deposited directly into your bank account.

Google announced the referral program through a post on its official Enterprise blog. "Many of the millions of Google Apps customers learned about tools like Hangouts, Drive and Gmail for business from their customers, friends and networks," Prajesh Parekh with the Google Apps marketing team, wrote in the post.

While there's no limit to the number of customers you can refer, you are only rewarded for 100 users per business. Also, referral amounts will be based on the number of users that have paid for at least 120 days. At present, the program is available for anyone based in the US and Canada.

Want to participate and earn some extra cash? Head over to Google's website for registration -- requires taxpayer ID number and bank account details. Once done, you'll receive a unique referral link, which you can share with your network through e-mail. What's more, you don't even have to think about what to write in the email, because Google has a predefined template you can use.
