Updated Sewage Payment and Invoicing Options
We are now offering the ability for you to set up automatic recurring monthly payments via credit or debit card. Our card service provider, CardConnect, offers the ability for us to enter your card information and store it on their secure site. You will need to have a valid e-mail account to receive a receipt of the transaction. Instead of receiving your monthly invoice and or statement via USPS, we will now only e-mail you your invoice and or statement each month and CardConnect will e-mail you a receipt for your payment.
If you would like to set up this service, please complete one of the forms below in its entirety, sign or initial where appropriate, and return it to our office. If you use the fillable form: open it, enter your information, save it and attach it in an email to mercertownship@zoominternet.net . If you use the printable form: print it, fill it out and either scan it and attach that file in an email to us, or mail it or drop it at the office in the drop slot. When we receive it, we can process a payment that same day. If your account is severely delinquent, please contact the office to set up a monthly payment plan to get your account paid up to date.
