Cogent has a monthly-based bill cycle that is processed after the 20th of the month. We bill a month in advance, so a bill for the January 20th cycle reflects your payment due for service from February 1 - February 28. For the first month that you receive service, you will have an invoice that reflects the prorated amount back to your installation date, PLUS the amount for the next month. For more information on this and all other invoice questions, please send an email to This email address is being protected from spambots.
