Paywitty has built-in support for shipping. If you do not want to use Paywitty shipping in your site, then you may not enable it from settings. But after activating Paywitty Shipping from settings, the seller still needs to activate the shipping method from his/her dashboard settings.

Dashboard  Settings Shipping Enable Shipping

Note that to be able to use the state-based shipping feature of Paywitty, it needs to be activated from settings. If you have enabled Paywitty shipping and configured the costs in the dashboard settings. Then you might leave all the settings as is. That means you do not have to input any data in this section. None of the fields are mandatory here.
