You can easily upgrade to another annual plan by visiting your accusonus account.
1) Login to your accusonus account.
2) Under the Subscriptions tab you can view and Manage your active Subscriptions.
3) Select Upgrade to view the available plans.
4) Select the new plan.
5) Your subscription to the new plan will start immediately and you will be charged with the relevant amount.
If a payment has already been processed for the previous annual plan, that amount will be deducted from the next one and you will be charged only with the price difference, regardless of when the plan change took place.
That amount is automatically calculated. Any prorated charges will be deducted from your invoice. The annual billing cycle will continue uninterrupted until the initial end date.
You started an annual subscription for ERA Bundle Standard ($119.88) in November. You decide that you want to upgrade to the ERA Bundle Pro ($239.88) in March. You will be charged with the price difference based on the prorated charges, and the annual subscription will end in November of next the year.
