Houston Car Sales should have provided you with a user name and password for logging into this payment portal. If they did not do so then please give them a call at (713) 434-3399 or use one of the other methods above to contact them.
Generally your login will be based on some of your account information. However, Houston Car Sales may have used another method for their customers so it is best to contact them if you are unaware of your login credentials.
If you have forgotten your credentials please contact Houston Car Sales at (713) 434-3399 to obtain them. Be prepared to provide them with account details to verify your identity.
If you have modified your credentials from the ones they gave you initially you can still use the original Houston Car Sales login and password to reset your account.
