After logging in to Socrative through the Socrative Website, click on your name at the top right corner and click Profile.
In the Account header, you'll be able to purchase Pro. A Learn More link is included that gives a quick overview of the Pro features available. When you're ready, click on Upgrade.
A new menu will expand where you can enter in how many seats you'd like and for how many years (up to 3). Enter in the coupon code here if you receive an email from one of our promotions!
You can also choose to apply a seat to your account this way. Seats corresponds to the number of teachers that can use the license key. Students are always free. The total price of Pro will be shown depending on how many seats and years selected (if you're buying for 3 or more teachers, use the Contact Us link to be eligible for bulk discounts). Once ready, click on Review and Pay.
Your order summary will be shown. Enter your payment information (credit card only) and click Purchase. Your receipt will be emailed to the email address you use to login to Socrative. The receipt will include the license key that you can use for your account and to share with your colleagues if you purchased for multiple seats.
