Welcome to the Williamson County Schools Online School Payments (OSP) portal. We hope to provide this service to Williamson County School parents to facilitate payment for school fees for a variety of products and services. Currently we are running the service to see if it meets the needs of our schools and families. If you have feedback that you feel will help us, feel free to e-mail your school bookkeeper. Thank you for your patience as we go through this evaluation process. If we determine that the tool meets our expectations, other schools will be added to the service.
