Interlaken Town Online Bill Pay

Return to Home Page>>>

Interlaken Town uses the SmartPay system to collect payments for water billing, building permits, and additional General fund billings.

Payments are accepted through bank transfers from checking and savings accounts. The town DOES NOT ACCEPT CREDIT CARD PAYMENTS. You'll need your bank's routing number and your account number as well as the Interlaken Town Invoice to complete your payment.

Accessing the SmartPay System

1. To open the SmartPay website, click this link:

Online Payment Portal>>>

2. From the website, click the PAY NOW button to make a quick payment.  This is the easiest way to make a single payment. It is not necessary to create an account unless you want to store all your payments for future access. You will be given a receipt upon completion of your payment.

3. Fill out the SmartPay form as follows:

Creating an Online Bill Pay Account

You can create a user account at any time to simplify making payments and track your payment history. This is entirely optional. You can always just use the PAY NOW> feature to pay a bill. Follow the links to create a user account. You do not need to fill out all the fields in the user account form. Just fill in the Secret Question and Secret Answer fields.

The first time you login in with your email, you'll have to click on Forgot username or password? in the login screen to establish a password. I know that's kind of weird, but that's how it works. The system uses the Email Address you entered in the bill pay form, and the Secret Question you entered but you can't enter a password until your 1st time logging in. Check your email for a link to establish your password. For the future logins, just enter your Email Address and that password.
