SLEMCO has seen substantial growth to our customer base over the last ten to fifteen years. In order for us to maintain efficiency, a restructure of our billing cycles was required. Customers affected by this change may see different billing and due dates. We do understand, and apologize, that this may be an inconvenience for some customers. Your Billing Department is here, and we are willing to work with each individual customer that may have been affected by this change. Please feel free to call us, at 337-896-5200, should you have any questions or concerns.
