You can upgrade your subscription to a higher package at any time.
Once you have completed the purchase though, it will not be possible to return to a lower level.

To begin the purchase procedure, access the control panel and click “Upgrade”.

The cost of the renewal will be calculated on the Purchase page and depends on the package you’ve chosen and its duration. You may get a discount on that price by inserting, if you have it, a promotional code.

The amount you will pay for the renewal is calculated by subtracting the value of the unused period of the previously purchased package from the price of the new one.

The formula is:
Cost of higher level package  – Cost of purchased package + ( Cost of purchased package/ Duration of purchased package X Number of days from previous activation).

You then must enter the necessary data for the invoice, accept the contract’s terms and conditions and select a method of payment.
If you pay with a credit card, click” Proceed” to go directly to a protected page (https) where you will be asked for your credit card details under Secure Servers Protocol.
