To upgrade your monthly plan to an Annual Complete Plan, log in to your OSP account. From the Dashboard, click the Upgrade to Annual button. You'll be directed to a page that will give you more info on going Annual, explain the features and benefits, and you can make a payment if you decide to upgrade.
Note: If you are a Annual subscriber you will be charged one time a year for your subscription to Online Sales Pro. If you are on a monthly plan, you'll be billed monthly on your bill date.
