What do I need?

Diamond Finance 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 (636) 940-8600 or use one of the other methods above to contact them.

Generally your login will be based on some of your account information. However, Diamond Finance may have used another method for their customers so it is best to contact them if you are unaware of your login credentials.

Merchant is Deactivated.

We apologize but Diamond Finance cannot accept payments at this time. Please contact them or check back later.

Forgot Credentials?

If you have forgotten your credentials please contact Diamond Finance at (636) 940-8600 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 Diamond Finance login and password to reset your account.
