How Port St. Lucie AutoPay and paperless billing work
Registered Port St. Lucie utility customers can set up automatic payments through the online payment system. The City says automatic payments can be set up with a checking account or credit card and are drafted on the bill due date.
Paperless billing is also available inside the registered customer account. The City says customers can log in and select the paperless option in the upper right-hand corner of the homepage.
- Open the official City Pay Bills page.
- Choose Pay Water or Sewer Bill.
- Register or log into your utility payment account.
- Review your invoice history and current balance.
- Set up AutoPay using checking account or credit card if desired.
