The telecommunications industry tends to bill calls in arrears and services in advance. So, at the start of the month when we produce your invoice, you will be invoiced for calls made in the previous month and you will be invoiced for services for the month ahead,

 

For any service that happened to be set up in the preceding month, you will also be charged for that portion of the month also: for example, if you added a new DDI to your end client on 20th March, in April’s billing run you will be (a) billed for any calls made from that DDI in March, (b) billed for the rental charge for that DDI from 1st-30th April, (c) billed for the rental charge for that DDI from 20th-31st March, (d) billed for any one-off set-up cost for adding a new DDI.

 

Conversely, if you cancel a service part way through a month, you’ll automatically be credited back the amount you’ve paid in advance: for example, in April you paid in advance for the service rental associated with a DDI but you cancelled the DDI on 28th April, so in May’s bill you will be: (a) billed for any calls made from that DDI in May, (b) credited back the rental charge for that DDI from 28th-30th April.
