Latest News ICMSA is offering several new options for our customers. We now offer the ACH Payment Option (automatic deduction), online bill pay, and e-billing. We also offer an online customer portal through which you can pay your bill, and view usage and payment history. Click on the following link to view the options electronically. ICMSA Customer Letter June 2018.docx Online Bill Pay Customers - If you pay through our website portal, your payment will post to your ICMSA account the next business day. If you pay through any other online bill payment service, such as your own bank, please allow plenty of time for us to receive your payment. Online bill payment services, such as your bank, cut and mail us a paper check. The transfer of funds is not automatic, and in some instances may take 7-10 days or longer depending on bank processing time and the postal service. In most instances, paper checks are entered and posted to our system the same day that they are received here at the office. Please take this into consideration if you are paying through any other online bill pay service other than ICMSA's.
