Our Annual subscription comes with a 40% discount on the monthly cost. You will be required to pay the accumulated 12-months fee in advance. Note that the annual subscription is subject to upgrades should the ad spend exceed the subscription terms. However, our system will only upgrade your subscription for the specific month you exceeded the spend limit. The additional charges will be calculated based on the difference between the two monthly plans (although you pay annually). The system will not upgrade your plan for months on which you did not exceed the limit.
