You can make a payment online through our client portal. Not all the links on our portal are active at this time. We are hoping more features are available in the future.
To access the portal: https://sherman.pimsyportal.com/
You have been assigned a username that is your first initial, last name, and eight digit birthdate.
If you are the responsible party on a minor's account, the username will be based on the client name.
For example: if Winnie The Pooh was born on 1/1/2001 his username would be wpooh01012001.
Your password will be your CLIENT ID and will appear on your statement or you can call the office for that information.
The first screen will be the HOME screen. It will provide some brief instructions and links to the other parts of the portal. Your balance will be listed in the middle of the screen with an option to Make a Payment below the balance.
Please call the office with any questions.
