Go to the Billing tab within Account Management to set up billing for your site. This includes:
Click on Change Address to change the billing address. Note, change the Company Name if billing is done through a different name than the name of the Account (i.e. The Account is "My Own CMS" but the company that runs it is "My Own Company Inc"). Invoices will be addressed here.
On the main billing screen, click on Change Credit Card to update your card information. NOTE: YikeSite does not store credit card information, rather it is passed on to the payment processor.
Click on on Submit to edit.
