In order to improve your Thomas customer experience, we have migrated our billing and payment operations to a new, improved system. Therefore it is time
to bid farewell to this TPCoService.com portal that has served us so well over many years.
From this point forward, you can make online payments for your Thomas account at our new payments site.
The new payments site requires a new set of login credentials -- your TPCooService login will not work there. If you are the billing contact for a
current Thomas account, you should already have received an email with the information you need to
access the new system. If you did not receive this information or have any other problems gaining access, please contact Thomas Customer Support.
