Social WiFi send all invoices on the 1st or each month.
Invoices are issued a month in advance, so for example, you will be issued an invoice on 1st January for your service throughout the month of January.
The only exception to this is if you begin the service part way through a month.
For example: You begin your Social WiFi on 10th January. Social WiFi will issue an invoice on 10th January for the period 10th January to 31st January. Your next invoice will then be on 1st February for the full month of February.
