That is great that you want to choose Starter Reseller Hosting plans.
For this Reseller Hosting Plan, You can make payments monthly by either of these possibilities:

Credit card – this type of payment allows you to pay for resources online. Contact technical support if your credit card brand is not supported. Sometimes, the account may require system administrator to approve of your registration, in which case the account will not be available immediately.

Check – you must send a check to the specified location. After the check is received, your account is made available for use. Check payments can be disabled.

PayPal – this type of payment allows you to pay for resources via online payment provider. Your credit card info won’t be stored in your billing profiles and billing info won’t show in the control panel. In order to pay via PayPal, you should have a web-based Personal account registered in the PayPal system.

WorldPay – this type of payment allows you to pay for resources via online payment provider. Your credit card and billing info won’t be stored in your billing profiles. In order to pay via WorldPay, you should have a web-based Personal account registered in the WorldPay system.
