Effective 9/1/2023, the convenience charge for online payments by credit or debit card will switch from a percentage calculation of the bill to a fixed fee of $3.  This is in addition to a fixed $1.25 municipal online fee charged by our accounting software firm.  Starting 9/1/23, each credit/debit card transaction fee will be a flat $4.25  This cost helps offset the fees paid by SAWCO for online bill pay services.
