A Domain Name is kind of like having a street address for your business. When people are trying to find you, they need to know where to look.
Domain Names are renewed annually. You may always choose to self-register your domain name via my secure GoDaddy Reseller website: https://www.greenwebdesign.net/.
Optionally, you may choose to have me register and manage the domain name. I will purchase the domain name and bill you each year.
