Is it possible to change the package to a higher and how is it settled?

The hosting package can be changed at any time in the customer panel: www.smarthost.eu/panel

By changing the package, a proforma invoice is automatically generated, which is the difference between the prices of hosting packages. The days that have been left until the end of the current accounting period will also be included. You pay only the difference in price and only for the part of the year that remained until the end of the settlement period.

At the time of paying the fee for exchanging the package with online payment - the change is made automatically at the time of payment.
