E-billing is the method of receiving your bills electronically, without the need for physical papers. When you apply to receive your bills via the e-billing method, you will receive an email notification informing you that the bill is available. This email will include both a link where you can easily view and pay your bill via MyGO, while it will also display the amount due.
This will give you the freedom to view your bills online wherever you are as long as you have an active internet connection. And by opting not to have any physical papers, you will be doing your bit for the environment.
